[0038] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention schematically. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0040] In the existing ship system services, due to the complexity of the system and the great difficulty in communication between development teams, data interaction between services and data integration between systems are extremely difficult. Since different system services establish different data models for the same data object, it will lead to problems such as difficult maintenance of the database due to excessive tables, difficult to guarantee data quality, and inability to share data between system services.

[0041] In view of the above problems, the present invention provides a service construction method based on multi-level ship data. The service construction method based on multi-level ship data includes classifying ship data, generating a corresponding tree-like ship directory and generating files under the corresponding ship directory for storing the ship data, establishing a theme database for storing the classified ship data, and providing APIs (Application Programming Interfaces) related to the theme database for other services to call. Since the ship data is classified and stored at multiple levels, the consistency of the same type of ship data in data format, data content, and data type is improved, the accuracy of the ship data is improved, and the access security of the ship data is enhanced.

[0042] In an embodiment of the present invention, the service construction method based on multi-level ship data is applied to a server. Specifically, please refer to Figure 1 , the service construction method based on multi-level ship data includes:

[0043] S11, obtaining ship entity data, input parameters and output parameters of the application programming interface. For example, the ship entity data may include: the defined name, type, field attribute name, field attribute type, and field attribute length of the ship entity object. The types of the input parameters and output parameters of the application programming interface may include: character, array, entity object, collection, and / or any combination of the above types.

[0044] S12. Classify and model the ship entity data to generate a hierarchical model of the ship entity data. Specifically, the ship entity data can be classified and modeled through algorithms and corresponding software. For example, the ship entity data can be divided into major categories such as comprehensive data, design data, production data, and management data, as well as corresponding sub-categories under the major categories, according to information such as the field attributes and defined names of the ship entity data. The number of layers of the major categories and their corresponding sub-categories can be set according to actual needs, and this number of layers is, for example, 6 layers. The hierarchical model of the ship entity data is a data model that organizes data in a tree structure. There is one and only one node in the hierarchical model that has no parent node, and this node is called the root node. Other nodes except the root node have one and only one parent node. Nodes in the hierarchical model that do not have sub-structures are used to store specific ship entity object information, and other nodes are used to store data category information such as comprehensive data and design data.

[0045] S13. Generate a tree-structured ship data directory according to the hierarchical model. The ship data directory includes a ship entity directory, and the ship entity directory conforms to the topological relationship of the hierarchical model. Specifically, the parent directories in the ship entity directory correspond one-to-one with the nodes in the hierarchical model that are used to store data category information, and the directory names are consistent with the category information. In addition, the ship data directory can be generated in sequence according to the sequential topological relationship of the hierarchical model.

[0046] S14. Generate ship data files under the corresponding ship data directory. The ship data files include the ship entity data, the input parameters, the output parameters, and entity attribute specification information. Specifically, the ship data files correspond one-to-one with the nodes in the hierarchical model that are used to store specific ship entity object information. The data structures that the ship entity data is used to store can include structured two-dimensional tables, wide tables, and hash tables, etc. The entity attribute specification information can include attribute length, attribute coding standard, attribute default value, attribute data format conversion, attribute description, etc. In addition, the input parameters and the output parameters included in the ship data files are used to implement the functions of the application program interface to add, modify, delete, and query ship data in the corresponding database. The data types of the input parameters and the output parameters can include any one of characters, arrays, objects, and sets. It should be noted that the above descriptions of the data structure, the entity attribute specification information, and the data types of the input parameters and output parameters are only optional solutions of this embodiment, but the present invention is not limited thereto.

[0047] Optionally, the ship data files include binary files that can cross hardware platforms and operating systems.

[0048] S15. Generate a ship entity database, which is used for data sharing and maintenance among multiple systems. Specifically, in this embodiment, the process of generating the ship entity database includes creating a ship entity data table, and the fields of the ship entity data table correspond one by one to the ship field attributes in S11.

[0049] In addition, due to the fact that some data in the ship industry is relatively long, there will be a problem of low database operation efficiency after being stored in the database. Therefore, in this embodiment, it is preferably to optimize the database by converting the storage field type of the ship entity data table. For example, a relatively long string that can be converted into an integer can be converted into an integer. Further, in practical applications, there will also be a problem that the length of some ship data is too long, even exceeding the length of the database text field, which seriously affects the database efficiency. To solve this problem, step S15 can first compress the ship data through the gzip (Compressed File Archive) compression algorithm, and then continue to compress it through the database compression algorithm, and finally store the ship entity data in the database binary large object type. This method can effectively reduce the size of the stored data and improve the operation efficiency of the ship entity database.

[0050] S16. Create an application program interface of the ship entity database based on the ship data file, and the application program interface of the ship entity database is used to provide services to other systems. Specifically, create an application program interface of the ship entity database under the corresponding ship data directory according to the ship data file, and generate an application program project according to the application program interface. Then, the server can provide services to other systems through the application program interface. Among them, the generation framework of the application program project includes the WEBAPI (World Wide Web Application Programming Interface) framework based on the NETCore technology.

[0051] According to the above description, it can be known that the service construction method based on multi-level ship data described in this instance classifies and models the ship entity data, establishes a tree-shaped ship data directory, and realizes the service sharing between different service systems and the improvement of data quality and other effects through operations such as generating ship data files, generating a ship entity database, and creating an application program interface of the ship entity database under the corresponding ship data directory. And by optimizing the fields of the ship entity data, the storage quality of the ship entity data and the operation efficiency of the ship entity database are improved.

[0052] Please refer to Figure 2, in an embodiment of the present invention, the service construction method based on multi-level ship data further includes:

[0053] S21, obtaining the test cases for the hierarchical model; for example, the server can directly obtain the test cases according to the user's input, or obtain the test cases from the corresponding test case database, or generate the test cases in an automatically generated manner by the device. The present invention does not limit this.

[0054] S22, using the test cases to detect the hierarchical model to determine whether the hierarchical model is available; specifically, it can be determined whether the hierarchical model is available by instantiating the test cases related to the hierarchical model and according to the instantiation result.

[0055] S23, when the hierarchical model is not available, generating an error prompt message and jumping to the step of generating the ship data directory, that is, Figure 1 step S13 in. Specifically, when an error occurs in the instantiation result, it is necessary to modify the ship entity object information included in the hierarchical model and regenerate the ship data directory.

[0056] According to the above description, it can be known that the service construction method based on multi-level ship data described in this embodiment can ensure the storage quality of the ship entity data by detecting the ship entity object information included in the hierarchical model.

[0057] Please refer to Figure 3 , in an embodiment of the present invention, the service construction method based on multi-level ship data further includes:

[0058] S31, obtaining the configuration information of the application program interface. Specifically, the configuration information of the application program interface may include interface name, interface description, interface routing, access security policy, request method, request parameters, response parameters, etc. Among them, the request method only supports the POST request method and the GET request method.

[0059] Optionally, the configuration information of the application interface may further include database connection information, such as database type, database service address, database name, database account, database password, etc.

[0060] S32, assigning corresponding parameters to the application program interface according to the configuration information to implement the configuration of the application program interface. Specifically, for example, the application program interface can be associated with the input parameters and output parameters included in the ship data file to implement the configuration of the application program interface. By configuring the application program interface, the operation of the ship entity database can be realized through the application program interface.

[0061] As can be seen from the above description, in this embodiment, by configuring the application programming interface and associating the application programming interface with the input parameters and output parameters included in the ship data file, it is possible to operate on the ship entity database through the application programming interface.

[0062] Please refer to Figure 4 , in an embodiment of the present invention, the implementation method for creating the application programming interface includes:

[0063] S41, create a theme library application programming interface project under the directory path of the application programming interface. Specifically, a corresponding theme library application programming interface project can be automatically generated under the path of the application programming interface according to the application programming interface.

[0064] S42, receive the compiled theme library application programming interface project and generate an access base address. Specifically, after the theme library application programming interface project is compiled, it is deployed on a formal server, and the access base address can be generated according to the corresponding server domain name and IP (Internet Protocol) address.

[0065] Optionally, the base address can be used, when separating the front end and the back end, to solve the situation of being restricted by the back-end call during the front-end service containerization process by dynamically inserting the base address of the application programming interface, thereby effectively reducing the workload of building the image.

[0066] S43, generate a theme library application programming interface address that can be accessed by other systems. Based on the base address, generate a theme library application programming interface address that can be accessed by other systems.

[0067] Optionally, the implementation method for creating the application programming interface in this embodiment may further include: testing the theme library application programming interface address. Specifically, the application programming interface is tested by assigning values to the application programming interface parameters to check whether the application programming interface executes normally.

[0068] S44, publish the application programming interface address. Specifically, the tested application programming interface address is published, and the published application programming interface address can be accessed by other service systems.

[0069] Optionally, the implementation method for creating the application programming interface in this embodiment may further include: generating a call document for the application programming interface for use by other service systems.

[0070] According to the above description, in this embodiment, by generating and publishing the application programming interface address, the theme library application programming interface can be called by other service systems, thereby satisfying the sharing of the theme library interface service and theme library data by different service systems.

[0071] In an embodiment of the present invention, the service construction method based on multi-level ship data further includes generating a key for the application programming interface, and the key is used to determine the access permission of the system. Specifically, the key includes a key name and key information, and the key information includes encrypted information such as an authorized domain name and an authorized time. When the application programming interface is accessed by other service systems, the other service systems need to obtain the key to successfully access, thereby playing a role in improving the security of the application programming interface service.

[0072] Please refer to Figure 5 , in an embodiment of the present invention, the service construction method based on multi-level ship data includes:

[0073] S51, obtaining ship entity data, input parameters and output parameters of the application programming interface. Specifically, the ship entity data may include: the defined name, type, field attribute name, field attribute type, and field attribute length of the ship entity object. The types of the input parameters and output parameters of the application programming interface may include: character, array, entity object, collection, and / or any combination of the above types. The defined name of the ship entity object and the field attribute name need to meet the specifications. For example, the first letter before each syllable word of the defined name of the ship entity object is capitalized, and the field attribute name is different according to different data categories. For example, when the field data is static data, all letters are capitalized, and when the field data is basic data, the first letter of the first word is lowercase. The name specifications of the input parameters and output parameters of the application programming interface are the same as those of the basic data of the field data, which will not be elaborated here.

[0074] S52. Classify and model the ship entity data to generate a hierarchical model of the ship entity data. Specifically, classify and model the ship entity data through algorithms and corresponding software. According to information such as the field attributes and defined names of the ship entity data, the ship entity data is divided into major categories such as comprehensive data, design data, production data, and management data, as well as sub-categories defined under the major categories. In this embodiment, the major categories and their corresponding sub-categories can support up to 6 layers at most. The hierarchical model of the ship entity data is a data model that organizes data in a tree structure. In the hierarchical model, there is one and only one node without a parent node, and this node is called the root node. Other nodes except the root node have one and only one parent node. Nodes in the hierarchical model that do not have sub-structures are used to store specific ship entity object information, and other nodes are used to store data category information such as comprehensive data and design data.

[0075] S53. Generate a tree-structured ship data directory according to the hierarchical model. The ship data directory includes a ship entity directory, and the ship entity directory conforms to the topological relationship of the hierarchical model. Specifically, the parent directories in the ship entity directory correspond one-to-one with the nodes in the hierarchical model used to store data category information, and the directory names are consistent with the category information. In addition, when generating the ship data directory, it can be generated in sequence according to the topological relationship of the hierarchical model. In addition, in this embodiment, the name of the ship data directory needs to meet the specification, and the letters of each word are in lowercase.

[0076] S54. Generate ship data files under the corresponding ship data directory. The ship data files include the ship entity data, the input parameters, the output parameters, and entity attribute specification information. Specifically, the ship data files correspond one-to-one with the nodes in the hierarchical model used to store specific ship entity object information. The data structures that the ship entity data can be used to store can include structured two-dimensional tables, wide tables, and hash tables, etc. The entity attribute specification information can include: attribute length, attribute coding standard, attribute default value, attribute data format conversion, attribute description, etc. In addition, the input parameters and the output parameters included in the ship data files are used to implement the functions of the application program interface to add, modify, delete, and query ship data in the corresponding database. The data types used to store the input parameters and the output parameters can include any one of characters, arrays, objects, and sets.

[0077] Optionally, the ship data files include binary files that can cross hardware platforms and operating systems.

[0078] S55. Detect the hierarchical model information of the ship entity data. Specifically, the implementation method for detecting the hierarchical model information of the ship entity data includes: obtaining the test cases related to all specific ship entity object information in the hierarchical model; instantiating the test cases related to the hierarchical model; judging whether the hierarchical model is available according to the instantiation result. When an error occurs in the instantiation result, modify the ship entity object information included in the hierarchical model and regenerate the ship data directory. When the instantiation result is correct, execute step S56.

[0079] S56. Generate a ship entity database, which is used for data sharing and maintenance of multiple systems. Specifically, the process of generating the ship entity database includes creating a ship entity data table, and the fields of the ship entity data table correspond one by one to the ship field attributes in S51. In addition, the process of generating the ship entity database also includes the login test of the database connection and the generation of the database table. The login test of the database refers to testing whether the database connection can be logged in normally by obtaining information such as the type, server address, name, account, and password of the database. The generation of the database table refers to completing the generation operation of the database table by receiving a computer instruction, and the computer instruction includes information about the ship entity database, the ship entity database table, and the fields related to the ship entity database table.

The implementation method of the application programming interface for creating the ship entity database based on the ship data file includes: obtaining the configuration information of the application programming interface; assigning corresponding parameters of the application programming interface according to the configuration information to implement the configuration of the application programming interface; creating a theme library application programming interface project under the directory path of the application programming interface; receiving the compiled theme library application programming interface project and generating an access base address; generating a theme library application programming interface address that can be accessed by other systems; generating a key for the application programming interface, and the key is used to determine the access permission of the system; publishing the application programming interface address; testing the application programming interface address. Specifically, associating the application programming interface with the input parameters and output parameters included in the ship data file and receiving relevant code instructions can realize the operation of the ship entity database through the application programming interface. Secondly, generating a corresponding application programming interface project according to the application programming interface, and the generation framework of the application project includes a WEBAPI framework based on the NETCore technology, and then completing the creation and configuration of the application programming interface project, and deploying it on the formal server by compiling, debugging, publishing to a determined path. Generating an access base address according to the domain name and IP address of the server, and generating a theme library application programming interface address that can be accessed by other systems according to the base address. In addition, in order to ensure that the application programming interface project is not maliciously accessed, it is also necessary to generate a key for the application programming interface to determine the access permission of the system. Finally, publishing the application programming interface address and testing, and generating a call description document for other systems to view at the same time. When other systems call the application programming interface, they need to obtain the address and key information of the application programming interface to normally call the application programming interface. When the application can be normally called, it means that the test is successful. The configuration information of the application programming interface includes interface name, interface description, interface route, access security policy, request method, request parameters, response parameters, etc. The request method only supports the POST request method and the GET request method. Optionally, the configuration information of the application interface also includes database connection information, such as database type, database service address, database name, database account, database password, etc.

[0081] According to the above description, the service construction method based on multi-level ship data in this embodiment includes classifying and modeling ship entity data, generating a ship data catalog, generating a ship entity database, etc. Compared with the conventional service construction method, this method can construct a ship entity database based on a unified entity model under a unified ship data catalog, and construct an application program interface service according to input and output elements, so as to realize the rapid construction and access of ship application services, while ensuring the consistency of the same type of ship data in data format, data type, and data content, and improving data accuracy and access security.
