基于J2EE的彩铃管理系统数据库访问的改进

IMPROVEMENT OF DATABASE ACCESS FOR COLOR RING BACK TONE MANAGEMENT SYSTEM BASED ON J2EE

随着彩铃用户数量的增多以及用户对管理业务属性丰富性需求的增长,原有彩铃业务管理平台在逐渐增多的彩铃功能需求中也逐渐暴露出弊端,其中对数据库访问的效率和性能问题是整个系统性能提升的关键.基于轻量级J2EE开发框架,采用Hibernate持久化技术,使用Bridge模式对彩铃服务的数据库访问层重新设计,从而与业务逻辑分开,最大限度地提高数据库访问层的代码可靠性及复用性,达到管理业务逻辑对管理接入方式的透明,并降低维护阶段对业务及管理业务修改的风险.

Along with the increasing of users, as well as the growth of richer service attributes demand, the gradual increase on demand of CRBT （color ring back tone） functionality, the defects of original CRBT management platform are gradually revealed. Especially, the efficiency and performance of database access are the key point. Based on the lightweight J2EE development framework, using Hibernate persistent technical and Bridge mode, to separate the details of the CRBT service database access and business logic. It increased the applicability of the database access maximize. Data storage is not one that corresponds to a database. The use of relational database is no longer the only one, and can transplant between oracle, sqlserver, mysql database and so on. So the application scope of CRBT management system is expanded.
