Method and apparatus of caching multiple Java-database connectivity

摘要

PURPOSE: A system for a cache capable of connecting multiple Java database and a method thereof are provided to manage data state and dynamic data for maintaining a consistency of the dynamic data stored in the cache. CONSTITUTION: A cache manger(103) is provided between an intermediate server(102) and a database server(104). The intermediate server(102) stores frequently requested data out of dynamic data requested to the database server(104) in a cache memory. If a Java application program requests to access a database as a standardized query sentence, the intermediate server(102) transmits a command to the database server(104). The cache manger(103) analyzes the query sentence requested to the database server(104) from the intermediate server(102) and the latest contents of the corresponding data exist in the cache memory. The command is not transmitted to the database server(104), and contents in the cache memory are transmitted to the intermediate server(102). The cache manger(103) stores the latest contents with respect to a frequently requested query sentence in the cache memory.
