Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0041] FIG. 1 is a schematic diagram of an integrated development environment (IDE) system for automatically establishing a relational model in an embodiment of the present invention. The system mainly includes a model information acquisition engine and an automatic conversion engine. Wherein the model information collection engine acquires the model association information from the object model, and then sends the model association information to the automatic conversion engine; the automatic conversion engine generates the mapping file and the object model according to the preset mapping rule definition file, the model association information and the object model Relational model, users can use the obtained relational model to access the database. The collection process of the model in...

Abstract

The present invention discloses a method for automatically creating relationship model. Said method includes the following steps: setting mapping rule of object model to relationship module and collecting model associated information from object model; and utilizing the described mapping rule, collected object model associated information and object model to automatically generate relationship model. Said invention also provides a system for automatically creating relationship model. Said system includes model information collecting engine, it is used for collecting associated information between models from object model and transferring said described model associated information to automatic conversion engine; and automatic conversion engine, it is used for automatically generating relation ship model according to the preset mapping rule definition file, the described model associated information and object model.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a system and method for automatically establishing a relational model. Background technique [0002] At present, the architecture of the JAVA2 Enterprise Edition (J2EE) system is usually divided into three basic levels in the application: the presentation layer, the business logic layer and the data source layer. It is used to process business logic in various fields, and the data source layer is used to process connections with relational databases and message systems, and to complete functions such as transaction management. Among the above three basic levels, the data source layer is a very important level. In practical applications, most application scenarios of data sources are relational databases. [0003] In the J2EE architecture, relational databases can be accessed directly through JAVA database connection technology (JDBC), which is also the data access method adopt...
