One embodiment of the invention employs techniques for providing a default object-relational mapping between persistent data objects (i.e., the objects that represent persistent data from a database) and a relational database. In a Java environment, for example, each entity bean is mapped to a particular database table, and each of the persistent fields within the entity bean are mapped to columns of the database table. Relationships between entity beans are expressed as mappings between primary keys and foreign keys within the database schema. Dependent-value persistent fields may be mapped to multiple columns or to a single column of a special Java type (java.sql.Types. BLOB). In addition, one embodiment of the invention generates a default database schema using the default O/R mapping by executing a series of SQL commands generating the tables and columns.

The present invention discloses an object relational mapping method and device as well as a processor. According to the method, when data in a database table are required to be queried, an alias name of the database table corresponding to a current query and a physical field of the database table are determined according to received database operation statements and query parameters, and a corresponding table connection relationship is constructed; and then corresponding object data are returned according to received object operation data and a preset mapping relationship. The method achieves object relational mapping, can be applied to a complicated data model and is used for solving the problem of confused coding in the existing hard coding technology; in addition, according to the object relational mapping method disclosed by the present invention, current query conditions and table connection relationships can be assembled according to object data and mapping files, so that the flexibility is high, and the degree of multiplexing is high.

The invention discloses a method and a device for achieving efficient database access based on an ORM (object relational mapping) architecture. The method comprises the following steps that: a code generator module generates a data entity code of a database table according to the database table; an ORM module builds a mapping relationship between the entity data and corresponding database according to the data entity code, and a data access module accesses the database requested by a user by the mapping relationship. According to the invention, efficient access on different databases by different development languages is achieved; business data is transferred between layers in an object-oriented manner by adopting an effective layering architecture design; maintainability and expandability of the program are improved; labor division of each layer is explicit; agile development and co-operative development are convenient, and load of an application developer is reduced by automatically generating most of SQL (structured query language) sentences and entity class components, so that more energy is input on achievement of a view layer design and a system service logic function and the like.

A system and method are provided for communicating with a Structured Query Language (SQL) statement generator. In an embodiment, an SQL mapper factory receives an object-relational mapping schema to define a mapping between one or more persistence fields of one or more Enterprise Java Beans (EJBs) and one or more tables of a database.

In an embodiment, the SQL mapper implementation may be generated based, at least in part, on the object-relational mapping schema.

In an embodiment, a generic database application of a computer system receives a portion of input data from a database. The generic database application can communicate with the database using a variety of different database schemas. The generic database application of the computer system infers a portion of ORM metadata associated with the received input data.

The invention provides an indexing and retrieval system based on HBase-ORM (Object Relational Mapping). Insertion, reading and modification of data are finished by automatically establishing a mapping relation between an underlying database table and an upper database object; a database layer is separated from a data access layer, so that upper developers can pay more attention to upper service logical processing, and the development efficiency is improved; meanwhile, the error rate is reduced; an index of each line of data in HBase is established according to different types by using Elastic search, and fuzzy query of texts, interval query of values, range query of longitude and latitude and similarity query of images are realized, so that real-time query demands of Web users on different data types are met.

The invention relates to an object relationship mapping model with a fixed database schema, which can store object-oriented information modeling elements (such as entities, attributes, relationships and the like). The invention is suitable for specific programming environments in which the database table structure can not or is not allowed to change and the users must be allowed to store various user defined data after the software development is completed and the software is delivered to the user. Since the database model uses limited number of database tables, when an object in a new format needs storing, the user does not need to create a database table and only needs to insert a new record into the fixed database table. The model supports the object-oriented information modeling concept, such as entities, relationships, attributes and the like, thereby ensuring that the information model reflecting the real world can be smoothly mapped to the fixed database schema.

Techniques for object relational mapping in database technologies are described herein. According to one embodiment, in response to a query statement for accessing a relational database, a syntax tree is generated to represent semantic information of the query statement, where the query statement has a boolean parameter and is implemented as an SQL object. A data type of the boolean parameter is predicted based on the semantic information obtained from the syntax tree in view of a structure representing the syntax tree. The boolean parameter is configured to be either a numeric value or a string dependent upon metadata used to map the SQL object to the relational database. Other methods and apparatuses are also described.
