Applied Research Of The Middleware Technology In The Telecom Operating System

当前的计算模式正在由集中主机系统向三层架构或多层架构的分布式系统迁移,在这种系统中,中间件为应用提供通用服务,占据十分重要的地位。设计并实现了一个通用的中间件平台AIBASE,该平台包括通用事务处理中间件AIIP和通用数据库中间件AIDB, AIIP用于封装各种交易中间件,AIDB用于封装各种数据库。描述了CICS系统下实现中间件的应用方法。本文重点研究了通用数据库中间件AIDB。对当前各种数据库接口的进行了比较分析,通过对Java下的数据库中间件JDBC的分析,设计了一种基于面向对象的通用数据库中间件AIDB,并给出关键算法描述。AIDB包括三个部分:抽象数据库访问接口,不同数据库的驱动程序以及驱动管理程序。AIDB的实现可以满足像电信这样的对系统运行效率有较高要求的行业。The current computing model is being used by centralized mainframe systems to three-tier or multi-layer architecture, distributed systems migration, in this system, middleware, common services for applications, occupy very important position.Designed and implemented a common middleware platform AIBASE, the platform including a common transaction processing middleware, database middleware AIIP and General AIDB, AIIP is used to encapsulate a variety of transaction middleware, AIDB is used to encapsulate various databases.Describes the CICS system, achieved under the application of middleware approach.This paper focuses on a common database middleware AIDB. Interface to various databases on the current conduct of a comparative analysis of the database through the Java middleware JDBC under the analysis, design of a common database based on object-oriented middleware AIDB, and critical description of the algorithm is given. AIDB consists of three parts:an abstract database access interface, a different database driver and driver management procedures. AIDB implementation of telecommunications such as the right to meet the operational efficiency of the system has high demand industries.
