【摘要】 对VC++环境下几种数据库访问技术的优缺点进行了简要的分析,并提出了一种利用DAO技术对ADO数据访问代码进行封装的数据库访问策略。这种策略不仅具有ADO的优点,而且使数据访问层与业务逻辑层分开,提高了数据访问代码重用率。更多还原

【Abstract】 Merit and flaw of some database access technologies in VC++ surroundings are analyzed briefly and a database access strategy that ADO data access codes are encapsulated by DAO technology idea is put forward.The strategy not only has the merit of ADO,but also detaches data access layer and business logic layer and increases repeat using rate of data access codes.更多还原
