Abstract

The invention discloses an optimization method of a data base. The optimization method comprises the following steps: obtaining class information of a virtual machine before loading, and analyzing the class information to ensure data base drive class information of the class information; weaving a first code and a first operation class code into the data base drive class information; obtaining data base operation statements according to the first code and the first operation class code which are weaved; and optimizing the data base according to data base operation statements. The method can intercept the data base operation statements under the condition of no invasion, and further optimizes the data base according to the data base operation statements obtained by being intercepted, so that the performance of the data base is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a database optimization method and device. Background technique [0002] JDBC (Java Data Base Connectivity, Java Database Connection) is a Java API (Application Programming Interface, Application Programming Interface) for executing SQL (Structured Query Language, Structured Query Language) statements, which can provide various relational databases Unified Access, which 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. With the JDBC API, it is very easy to send SQL statements to various relational data. In other words, with the JDBC API, there is no need to write a program specifically for accessing the Sybase database, another program for accessing the Oracle database, or another program for accessing the Inf...
