[0003] A relational database is a database that uses a relational model to organize data. Relational databases such as SQLite are widely used in various terminal devices such as embedded devices. How to process data in a relational database more efficiently has become a focus of attention.

[0004] In the related technical solutions, object-oriented object models are used for data processing in the business logic layer and the user interface layer, and relational models are used for data processing in the database layer. However, since the object model does not match the relational model, SQL statements are required to perform data processing operations on objects in the relational database, such as adding data, deleting data, etc. Summary of the invention

It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] According to an embodiment of the present disclosure, a data processing method, apparatus, computing device and medium are proposed.

[0047] In this article, it is important to understand that the terms involved are:

[0048] ORM (Object Relational Mapping): ORM framework is a technology to solve the problem of incompatibility between object-oriented and relational databases. Through the ORM framework, you can operate the tables in the database like operating objects. Under the ORM framework, a class object corresponds to a data table in the database, each instance of the class object corresponds to a record in the data table, and each attribute of the class corresponds to a field in the data table.

[0049] Library-table correspondence: The database includes multiple sub-libraries, each of which has multiple tables. The library-table correspondence is used to record the correspondence between the sub-libraries in the database and the tables in the sub-libraries. This correspondence can be implemented through the MAP data structure.

[0050] URI (Universal Resource Identifier): the path information of the storage location of a data table in a database. The corresponding data table in the database can be accessed through the URI of the data table.

[0051] Table-address correspondence: the correspondence between the identification information of the data table in the database and the URI corresponding to the data table. This correspondence can be implemented through the MAP data structure.

[0052] Table-class correspondence: the correspondence between the identification information of a data table in the database and the class file of the data table. This correspondence can be implemented through the MAP data structure.

[0053] In addition, any number of elements in the drawings is for illustration and not limitation, and any naming is only for distinction and does not have any limiting meaning.

[0054] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure. SUMMARY OF THE INVENTION

[0056] The inventors have found that in order to solve the problem that it is difficult to efficiently process data on a relational database, it is necessary to use SQL statements to process data on a relational database due to the mismatch between the object model and the relational model. In the related technical solution, an ORM (Object Relational Mapping) framework is used to process data on a relational database. The ORM framework is a technology for solving the mismatch between object-oriented and relational databases. Under an ORM framework such as GreenDao, objects in an application are automatically persisted in a relational database by using metadata describing the mapping relationship between objects and data tables. However, as the business develops, the amount of data in the database will increase, and a single database will affect the database data processing performance.

[0057] Based on the above content, the basic idea of ​​the embodiment of the present disclosure is: using a database based on the ORM framework, establishing a library-table correspondence between the sub-library of the database and the data table in the corresponding sub-library, and performing data processing operations on the relational database through the library-table correspondence. On the one hand, using a database based on the ORM framework, it is possible to establish a mapping relationship between the object model and the relational model, so that data processing operations can be efficiently performed on the relational database through the mapping relationship; on the other hand, establishing a library-table correspondence between the sub-library of the database and the data table in the corresponding sub-library, performing data processing operations on the relational database through the library-table correspondence, and being able to perform sub-library processing on the ORM database, thereby improving the concurrent processing performance of the ORM database and avoiding the problem of reduced database processing performance due to large data volume.

[0058] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0059] Application Scenario Overview

[0060] It should be noted that the following application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0061] Figure 1A block diagram schematically shows an application scenario of the data processing method according to an embodiment of the present disclosure.

[0062] Reference Figure 1 As shown, the application scenario may include: at least one client 110 and a server 120, wherein the client 110 is installed with a variety of applications such as music applications, video applications, etc. The client 110 and the server 120 communicate through a network 130. The client 110 may be a terminal device such as a mobile phone, a tablet computer, a desktop computer, a portable notebook computer, or a vehicle-mounted terminal. The server 120 may be a physical server including an independent host, or a virtual server carried by a host cluster, or a cloud server, etc. The network 130 may be a wired network or a wireless network, for example, the network 130 may be a PSTN (Public Switched Telephone Network) or the Internet.

[0063] In some example embodiments, the target application is a music player application, and an ORM-based database is provided on the client 110. The database includes multiple sub-libraries. The database corresponds to the music player application on the client 110. The music player application is configured with a database information class file. The database information class file is used to record the library-table correspondence between the sub-libraries of the database and the data tables in the corresponding sub-libraries. A data processing operation is performed on the music player application on the client 110, such as adding the currently played music to the favorite song list. In response to the data processing operation on the music player application, the client 110 determines the identification information of the data table to be processed corresponding to the data processing operation, such as the identification information of the favorite song list; based on the identification information of the data table to be processed and the library-table correspondence, the sub-library information corresponding to the data table to be processed is determined; the data table to be processed, such as the favorite song list, is queried from the sub-library corresponding to the sub-library information, and a data processing operation, such as a song collection processing operation, is performed. Further, the client 110 can upload the newly added data in the database corresponding to the music player application to the server 120.

[0064] In other example embodiments, an ORM-based database is provided on the server 120, and the database corresponds to the music playing application on the client 110. The music playing application is configured with a database information class file, and the database information class file is used to record the library-table correspondence between the sub-library of the database and the data table in the corresponding sub-library. When a data processing operation is performed on the music playing application on the client 110, such as adding the currently playing music to the favorite playlist, the server 120 determines the identification information of the data table to be processed corresponding to the data processing operation, such as the identification information of the favorite playlist, in response to the data processing operation on the music playing application; determines the sub-library information corresponding to the data table to be processed based on the identification information of the data table to be processed and the library-table correspondence; queries the data table to be processed, such as the favorite playlist, from the sub-library corresponding to the sub-library information, and executes data processing operations, such as song collection processing operations.

[0065] It should be noted that although the target application is a music playback application as an example, a person skilled in the art should understand that the target application of the embodiment of the present disclosure may also be other appropriate applications such as video applications, information applications or shopping applications, which are also within the scope of protection of the present disclosure.

[0066] It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0067] Exemplary Methods

[0068] In combination with the above application scenarios, refer to Figure 2 The data processing method according to the exemplary embodiment of the present disclosure is described. The data processing method can be applied to Figure 1 The ORM database set on the client 110 or server 120 corresponds to the target application on the client 110. Figure 2 An exemplary embodiment of the present invention is described in detail.

[0069] Reference Figure 2 As shown, in step S210, in response to a data processing operation on a target application, identification information of a to-be-processed data table corresponding to the data processing operation is determined.

[0070] In the example embodiment, under the ORM framework, a class object corresponds to a data table in the database, each instance of the class object corresponds to a record in the data table, and each attribute of the class corresponds to a field in the data table. Through the ORM framework, the table in the database can be operated like an object. On the client 110, a data processing operation is performed on the object on the target application, and the identification information of the data table to be processed corresponding to the data processing operation is determined.

[0071] For example, assuming that the target application is a music playing application, and the object on the music playing application is the currently playing music, when the currently playing music of the music playing application is added to the favorite playlist on the client 110, the client 110 responds to the collection processing operation on the currently playing music of the music playing application, and determines the identification information of the favorite playlist corresponding to the collection processing operation.

[0072] It should be noted that although the target application is a music playback application as an example, a person skilled in the art should understand that the target application of the embodiment of the present disclosure may also be other appropriate applications such as video applications, information applications or shopping applications, which are also within the scope of protection of the present disclosure.

[0073] In step S220, based on the identification information of the data table to be processed and the library-table correspondence, the sub-library information corresponding to the data table to be processed is determined.

[0074] In an exemplary embodiment, the database corresponding to the target application includes multiple sub-libraries, each of which stores a data table. The target application is configured with a database information class file, which is used to record the library-table correspondence between the sub-libraries of the database and the data tables in the corresponding sub-libraries. The library-table correspondence can be a MAP data structure, which is a set of key-value pairs. For example, the key is the identification information of the table, and the value is the sub-library information of the table. There are three sub-libraries and 6 data tables. The library-table correspondence can be {(table1, sub-library 1), (table2, sub-library 1), (table3, sub-library 2), (table4, sub-library 2), (table5, sub-library 3), (table6, sub-library 3)}. Based on the identification information of the data table to be processed, the sub-library information corresponding to the data table to be processed is searched from the library-table correspondence of the MAP data structure.

[0075] For example, suppose the target application is a music player application, and the data table to be processed is a favorite playlist table. Perform a hash operation on the identification information of the favorite playlist table to obtain the corresponding hash value. According to the hash value of the identification information of the favorite playlist table, the corresponding sub-library information is searched from the library-table correspondence relationship.

[0076] It should be noted that although the data structure of the library-table correspondence relationship is taken as the MAP data structure as an example, those skilled in the art should understand that the data structure of the library-table correspondence relationship can also be other appropriate data structures such as a hash table data structure or a set data structure, which is also within the scope of protection of the present disclosure.

[0077] In some example embodiments, determining the sub-library information corresponding to the data table to be processed includes: determining the sub-library configuration information corresponding to the data table to be processed, the sub-library configuration information including one or more of the sub-library name, sub-library version, and corresponding operation type information.

[0078] In step S230, the data table to be processed is queried from the sub-library corresponding to the sub-library information, and a data processing operation is performed.

[0079] In the example embodiment, after obtaining the sub-library information, the data table to be processed is queried from the sub-library corresponding to the sub-library information, and a data processing operation is performed on the queried data table to be processed. For example, assuming that the target application is a music playing application, the data table to be processed is a favorite song list table, and the data processing operation is a favorite processing operation, the corresponding sub-library is determined according to the sub-library information, and the favorite song list table is queried from the corresponding sub-library according to the identification information of the favorite song list table, and a data adding operation of adding the currently playing music to the favorite song list table is performed, that is, a record is added to the favorite song list table.

[0080] It should be noted that although the data addition operation is used as an example for explanation, those skilled in the art should understand that the data processing operation can also be other appropriate processing operations, such as data deletion operations, data query operations or data modification operations, which are also within the scope of protection of the present disclosure.

[0081] In some example embodiments, the sub-library configuration information includes a sub-library name and a sub-library version, and querying the data table to be processed from the sub-library corresponding to the sub-library information includes: determining the corresponding sub-library according to the sub-library name and the sub-library version in the sub-library configuration information; and querying the data table to be processed from the corresponding sub-library.

[0082] according to Figure 2 The technical solution in the example embodiment, on the one hand, adopts a database based on the ORM framework, can establish a mapping relationship between the object model and the relational model, so that data processing operations can be efficiently performed on the relational database through the mapping relationship; on the other hand, a library-table correspondence between the sub-libraries of the database and the data tables in the corresponding sub-libraries is established, and data processing operations are performed on the relational database through the library-table correspondence, and the ORM database can be processed by sub-libraries, thereby improving the concurrent processing performance of the ORM database and avoiding the problem of reduced database processing performance due to large data volume.

[0083] In addition, in the example embodiment, the database information class file also records: the table-to-address correspondence between the identification information of the data table to be processed and the URI corresponding to the data table to be processed, and queries the data table to be processed from the sub-library corresponding to the sub-library information, including: based on the identification information of the data table to be processed, determining the URI of the data table to be processed from the table-to-address correspondence; based on the URI of the data table to be processed, querying the data table to be processed from the sub-library corresponding to the sub-library information.

[0084] Furthermore, in some example embodiments, the database information class file also records: a table-class correspondence relationship between identification information of the data table to be processed and the class file of the data table to be processed, and performs data processing operations, including: determining the class file of the data table to be processed from the table-class correspondence relationship based on the identification information of the data table to be processed; and performing the data processing operation on the queried data table to be processed based on the class file.

[0085] By recording the correspondence between the data table and the URI of the data table and the correspondence between the data table and the corresponding table structure information in the database information class file, the data processing operation is performed according to the above correspondence during the data processing operation, which not only improves the data processing efficiency, but also does not need to annotate the URI or table structure information of the data table in the database operation interface. In addition, since the application program interface call of the database operation can be simplified and parameter transmission through the application program interface call is avoided, the data processing efficiency is further improved.

[0086] Figure 3 The flowchart of the data processing method according to some other embodiments of the present disclosure is schematically shown.

[0087] In step S310, when initializing the target application, the database information class file is loaded.

[0088] In an example embodiment, when the target application is started, a database information class file is loaded from the file directory path of the target application. The database information class file is used to record the library-table correspondence between the sub-libraries of the database and the data tables in the corresponding sub-libraries.

[0089] For example, assuming that the target application is a music player application, when the music player application is started on the client 110, the code of the database information class file is loaded from the file directory path of the music player application.

[0090] In step S320, the library table correspondence relationship is read from the database information class file.

[0091] In an example embodiment, after loading the database information class file from the file directory path of the target application, the library-table correspondence is read from the database information class file. The library-table correspondence may be a MAP data structure. The MAP data structure is a collection of key-value pairs. For example, the key is the identification information of the table, and the value is the sub-library information of the table. The library-table correspondence is read from the MAP structure.

[0092] In step S330, the library table correspondence is stored in the memory corresponding to the target application.

[0093] In an example embodiment, the client 110 allocates a memory block for each running application, and stores the read library table correspondence relationship in the memory corresponding to the target application. Assume that the target application is a music playing application, the library table correspondence relationship is a MAP data structure, and the library table correspondence relationship of the MAP data structure is stored in the memory corresponding to the music playing application.

[0094] In step S340, in response to the data processing operation on the target application, identification information of the to-be-processed data table corresponding to the data processing operation is determined.

[0095] In the exemplary embodiment, the implementation process and effect of step S340 are substantially the same as those of step S210, and will not be described in detail herein.

[0096] In step S350, based on the identification information of the data table to be processed and the library-table correspondence, the sub-library information corresponding to the data table to be processed is determined.

[0097] In an example embodiment, the library-table correspondence is read from the memory corresponding to the target application; based on the identification information of the data table to be processed, the sub-library information corresponding to the data table to be processed is determined from the read library-table correspondence. For example, the library-table correspondence is assumed to be a MAP data structure, the data table to be processed is a favorite song list table, a hash operation is performed on the identification information of the favorite song list table, the hash operation value is used as the key KEY of the MAP data structure, and the sub-library information corresponding to the favorite song list table is determined from the MAP data structure through the KEY.

[0098] In step S360, the data table to be processed is queried from the sub-library corresponding to the sub-library information, and the data processing operation is performed.

[0099] In the exemplary embodiment, the implementation process and effect of step S360 are the same as those of step S230, and are not described in detail herein.

[0100] according to Figure 3According to the technical solution in the example embodiment, on the one hand, the library-table mapping relationship is stored in the memory, and the sub-library information corresponding to the data table is determined according to the library-table correspondence relationship. Since the access time of the memory is short, the sub-library information of the data table can be efficiently obtained; on the other hand, the application program interface call of the database operation can be simplified to avoid passing parameters through the application program interface call, thereby further improving the data processing efficiency; on the other hand, data processing operations are performed on the relational database through the library-table correspondence relationship. Since the ORM database can be sub-library, the concurrent processing performance of the ORM database can be improved, thereby avoiding the problem of reduced database processing performance due to large data volume.

[0101] Figure 4 The structural diagram of a data processing device according to some embodiments of the present disclosure is schematically shown.

[0102] Reference Figure 4 As shown, the data processing device includes a database table management class 410, namely DBHelper, a database information class 420, namely DBInfo, and a database configuration class 430, namely DBConfig, wherein the database table management class 410, namely DBHelper, is used to batch process the table information in the sub-library when the sub-library of the database is created or upgraded, and each database table management class corresponds to a sub-library; the database information class 420, namely DBInfo: is used to record the corresponding relationship between the sub-library of the database and the data table in the sub-library, maintain the mapping relationship between the sub-library and the data table in the sub-library, and according to the database information class DBInfo, it is convenient to dynamically query the sub-library information corresponding to the data table during CRUD (i.e., add (Create), query (Retrieve), update (Update) and delete (Delete)) operations. The database configuration class 430, namely DBConfig: is used to maintain the information of each sub-library in the database, including the sub-library version, name and CRUD data operation management class, database name, etc.

[0103] according to Figure 4 The technical solution in the example embodiment, on the one hand, establishes a library-table correspondence between a database sub-library and a data table in the corresponding sub-library, and performs data processing operations on the relational database through the library-table correspondence, which can simplify the application program interface calls of database operations, avoid passing parameters through application program interface calls, improve data processing efficiency, and reduce the intrusiveness of database sub-libraries on the business; on the other hand, since the ORM database can be sub-library, the concurrent processing performance of the ORM database can be improved, avoiding the problem of reduced database processing performance due to large data volume; on the other hand, since the top-level call does not need to know which table is in which library, the need to manually remember to distinguish the relationship between sub-libraries and tables during database operations is avoided.

[0104] Figure 5 The flowchart of adding a new data table according to some embodiments of the present disclosure is schematically shown.

[0105] Reference Figure 5 As shown, in step S510, the database table correspondence between the identification information of the newly added data table and the identification information of the corresponding sub-library is recorded in the database information class file.

[0106] In an exemplary embodiment, in response to a table addition operation on a target sub-library in a database, a library-table correspondence relationship between identification information of the newly added data table and identification information of the target sub-library is recorded in a database information class file. For example, assuming that the target application is a music playing application, the database includes an original table sub-library and a newly added table sub-library, and when a new song list is created on the music playing application on the client 110, the client 110 records the library-table correspondence relationship between identification information of the newly added song list table and identification information of the newly added table sub-library in a database information class file in response to a table addition operation on the newly added table sub-library in the database.

[0107] Furthermore, the correspondence between the identification information of the newly added data table and the identification information of the target sub-library is recorded in the database information class file, including: recording the correspondence between the identification information of the target sub-library, the identification information of the newly added data table and the URI corresponding to the newly added data table in the database information class file; and / or recording the correspondence between the identification information of the target sub-library, the identification information of the newly added data table and the class file corresponding to the newly added data table in the database information class file.

[0108] Reference Figure 6 As shown, the database information class includes the table-class correspondence class TableClassInfo and the table-address correspondence class TableURIInfo, wherein TableURIInfo is used to record the correspondence between the identification information of the target sub-library, the identification information of the newly added data table, and the URI corresponding to the newly added data table, and TableClassInfo is used to record the correspondence between the identification information of the target sub-library, the identification information of the newly added data table, and the class file corresponding to the newly added data table. The establishment of these two correspondences or mapping relationship sets is to enable more efficient query of table information during database CRUD operations.

[0109] By recording the correspondence between data tables and their URIs and the correspondence between data tables and their corresponding table structure information in database information class files, data processing operations are performed according to the above correspondences, which not only improves data processing efficiency but also eliminates the need to annotate the data table's URI or table structure information in the database operation interface.

[0110] In step S520, the information of the newly added data table is added to the class file of the sub-library management class.

[0111] In the example embodiment, each sub-library corresponds to a sub-library management class, and the information of the newly added data table is added to the class file of the sub-library management class corresponding to the target sub-library. The sub-library management class is used to create the newly added data table in the target sub-library.

[0112] In step S530, the database is upgraded through the sub-library table management class.

[0113] In an exemplary embodiment, each of the sub-libraries corresponds to a sub-library table management class, and the sub-library table management class is used to handle the creation of data tables and database upgrades of the database sub-libraries. If a version upgrade operation is performed on the first sub-library in the database, then in response to a data migration operation of migrating the source data table in the first sub-library of the database to the second sub-library, the first sub-library table management class corresponding to the first sub-library and the second sub-library table management class corresponding to the second sub-library are determined. For example, assuming that the target application is a music playback application, the corresponding database includes: an original table sub-library and a newly added table sub-library, the first sub-library is the original table sub-library, and the second sub-library is the newly added table sub-library. When the database is version upgraded, in response to a data migration operation of migrating the source data table in the first sub-library of the database to the second sub-library, the first sub-library table management class corresponding to the first sub-library and the second sub-library table management class corresponding to the second sub-library are determined.

[0114] Further, in the example embodiment, a target data table corresponding to the source data table is created in the second sub-library through the second sub-library table management class; the data of the source data table is migrated from the first sub-library to the target data table of the second sub-library; and the source data table in the first sub-library is deleted through the first sub-library table management class. The following code shows the methods for creating and deleting tables in the sub-library table management class, namely the createAllTables method and the dropAllTables method. These two methods are used to be called when processing the upgrade and downgrade of the database sub-library, and are used to create data tables in the sub-library or delete data tables in the sub-library.

[0115]

[0116] according to Figure 5 In the technical solution of the example implementation example, on the one hand, by establishing a correspondence between a database sub-library and a library-table of a newly added data table, data processing operations are performed on the relational database through the library-table correspondence, which can simplify the application program interface calls of database operations and avoid passing parameters through application program interface calls; on the other hand, since the top-level call does not need to know which table is in which library, the need to manually remember and distinguish the relationship between the sub-libraries and tables during database operations is avoided.
