Embodiment Construction

[0056] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0057] In the prior art, when developing the data access layer, although JDBC provides developers with a set of standard APIs, in actual operation, different operators have different programming methods for constructing the database interface of the data access layer. The program structure modes of the data access layer are also different. Even in the same program mode, different operators will use different programming methods when maintaining and managing the data access layer. The amount is too much and the code is redundant, and it is easy to cause problems such as program structure confusion.

[0058] This application aims at some common problems existing in the data access layer development process...

Abstract

The invention provides a JDBC (java database connectivity) based data access layer building method and a device utilizing the same, which solve the problem that the system is complicated in configuration due to difference between the architecture of programs and the programming mode during development of the data access layer. The JDBC based data access layer building method includes: generating a JDBC based data access layer frame generating component which comprises an architecture component and function controls by integrating with a source opening component and packaging user-defined function members; selecting a program architecture according to the architecture component, selecting the corresponding function control according to the selected program architecture to generate system configuration files and source program templates applicable to the program architecture, and building a data access layer through relevant program configurations by the selected program architecture and the system configuration files and the source program templates thereof. By the generating component capable of generating the framework and members of the data access layer, complexity of system development is reduced and time thereof is shortened, and uniformity and standardization of development of the data access layer are realized.

Description

technical field [0001] The present application relates to database technology, in particular to a JDBC-based data access layer construction method and device. Background technique [0002] JDBC is a Java API for executing SQL statements that can provide unified access to various relational databases. It consists of a set of classes and interfaces written in the Java language. JDBC provides a baseline from which higher-level tools and interfaces can be built to enable database developers to write database applications. Among them, JDBC is Java Data Base Connectivity, java database connection; SQL is Structured Query Language; API is Application Programming Interface, application programming interface. [0003] In the development process of using JDBC to develop the data access layer of the Java system, accessing and operating the database, and providing the database operation results (datasets, data operation results) to the system service objects in a certain way, although ...
