摘要
根据数据访问的特点,利用ADO设计了一种基于COM+的数据访问组件,提供了数据操作接口,从而简化了数据访问,并同时能够将各数据库进行分布式处理、平衡数据流量、集成异构数据。组件在三层体系构架中处于中间层,隔离了用户界面层和数据库系统,逻辑清晰,可重用性强。
According to the characters of data access, a data access component based on COM + is designed via ADO, which provides interface for data operation and simplifies data access, distributes various databases to balance data flow and integrates heterogeneous data. The component belongs to middle layer of 3-tiered architecture, which separates user interface layer and database system, with clear logic and powerful reusable features.
