利用组件结构集成基于Web的应用

Integrate Applications Based on Web by UsingComponent Infrastructure

讨论了Ｉｎｔｅｒｎｅｔ环境下，数据库开发、应用中经常面对的一个重要问题－如何集成异构＼分布式的数据源，并实现使用简单、风格统一的用户界面。针对这个问题，提出了利用软件组件结构和Ｂｒｏｗｓｅｒ／Ｓｅｒｖｅｒ模式的解决方法，并进一步分析了这种方法的优点：代码重利用率高，互操作性强，平台无关、易于维护等。随后比较分析了各主要的组件结构（包括ＣＯＲＢＡ，ＤＣＯＭ以及ＪａｖａＢｅａｎｓ等）的特性和发展趋势。侧重ＣＯＲＢＡ，给出了企业ＭＩＳ系统实现分布式异构数据库基于Ｗｅｂ集成的一个实例。

Discusses an important problem which we are frequency faces in the developing and applyingof databases in the internet environment ---How to intergrate isomeric and distributed databases sources, andachieves an easy, consistent user interface style. We put forward a proposal ---- by using Software ComponentInfrastructure with Brower/Server model to solve this problem. Then analyses the advatages about this methoedon source code reusable, interoperability, applicability and maintainablility.Also compares the mainstramSCI(including CORBA, DCOM, and JavaBeans) model's characteristics. Emphasizing particularly onCORBA, the paper illustrates an integrated application based on Web by using Component Infrastructure in anenterprise MIS.
