摘　　要：针对DBAS中程序执行体与待处理数据集合之间的相对位置随环境变化而不断改变的特性,讨论了数据库引擎技术出现的必要性,介绍了其相关的产品,给出了5种实现数据源动态配置的方案及其优劣评价,并利用DELPHI描述了对应示例。According to the feature that the relative position between executable body of a program and a set of data to be handled by the program is continuously changing in DBAS, this paper focuses on the necessity of database engine technology and illustrates the correlation product based on the technology. At last, the paper offers five solutions to deploying data source dynamically and presents the good points and bad points toward evaluation of them, then describes an example based on DELPHI.
