Abstract

The invention provides a method and a device for accessing a database. According to the method and the device, the system performance and the development efficiency are beneficially improved, and besides, the standardization problem of interfaces is beneficially solved. The method comprises the following steps: receiving a class object and a value mapping table of a public interface class of a persistent layer, wherein the class object is obtained by abstracting the persistent layer as the public interface class; acquiring a value object according to the class object, and carrying out father entity filling on the value object according to the value mapping table and the class object; converting the filled value object into a persistent object; and storing data in the persistent object into the database.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for accessing a database. Background technique [0002] JDBC (JavaDataBaseConnectivity, java database connection) is a Java API for executing SQL statements, which 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. At present, very few J2EE applications will directly access the database in the form of JDBC. After all, using an object-oriented programming language to access a relational database requires a lot of work in the development process. Most of the time, J2EE applications use the ORM framework for data access. The ORM (ObjectRelationalMapping) framework uses metadata to describe the details of object-relational mapping. M...
