Abstract

An embodiment of the invention provides a database persistent layer device and a database operation method. The database persistent layer device comprises a pixel domain module, a pixel code mapping and code generating domain module and a database domain module, wherein the pixel domain module is used for providing a pixel editing environment, receiving design instructions on data objects represented in pixel form and input into the pixel editing environment by users and editing the data objects designed by the users to generate corresponding pixel describe files; the pixel code mapping and code generating domain module is used for analyzing the pixel describe files generated by the pixel domain module to generate corresponding plain old java object (POJO) and data access object (DAO); and the database domain module is used for mapping the generated POJO into a database table in the database and performing operation on the database table in the database and data members of the database table according to the generated DAO. By means of the embodiment of the data persistent layer device and the database operation method, automatic generation of data of the POJO and the DAO in a persistence layer can be achieved in the application program design, so that work amount of the persistence layer in the application program database is greatly reducd, and development efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a database persistence layer device and a data operation method. Background technique [0002] In application programming, the architectural design of the database persistence layer undergoes constant changes. [0003] The initial database persistence layer allows upper-layer applications to directly communicate with the underlying database using an interface similar to Java Data Base Connection (JDBC), such as figure 1 It shows that Structured Query Language (Structured Query Language, SQL) codes appear everywhere in the program codes of the business layer, which has the advantage of high code execution efficiency, which is feasible for small applications or prototypes. Its major disadvantage is that business logic is tightly coupled with data operations, which means that any change (such as renaming a column of a certain database table or porting to another databa...
