摘要
在现代企业信息管理和电子商务中,数据库技术被广泛应用于对企业数据进行有效管理,其中一个重要的研究课题是如何有效访问位于企业系统的后端数据库。介绍了J2EE架构下直接连接和池连接访问两种方式,并比较它们的性能优劣,然后在此基础上,针对远程客户机的访问对池连接方式作了进一步改进,提出通过本地缓存连接池引用,来改善远程客户机数据库交互的性能。最后使用仿真程序考察3种不同的数据库访问方式。测试结果证明带缓存的池连接访问确实能够为远程访问数据库带来明显的性能提升。
The database technology is widely used in enterprise information management, of which the effective access to database is one important point. This paper introduces two ways of database access in J2EE architecture： direct connection and pool connection, and makes a comparison of their performance. Then it analyses remote clients＇ access procedure and makes improvement by buffering reference of connection pool in local address. At last, the simulation experiment of three ways of database access is made, which proves that buffered pool reference does promote the remote client＇s performance of accessing database.
