摘要

讨论了使用VP-Expert实现数据库建模辅助工具database Designer (DBD)的设计和实现。DBD专家系统旨在帮助新手用户设计合适的数据库，方法是向用户询问问题，从而逐步构建扩展实体关系(ER)图的结构。作者讨论了他们针对DBD的系统设计方法和针对VP-Expert的具体实现问题，例如结合向后链接和正向链接、过程技术以及VP-Expert语句的透明度和可见性。该研究表明，采用系统化、结构化的方法，适当地注释代码和逻辑分组规则，可以使专家系统编程方法在设计复杂的过程设计应用程序(如DBD.>)时可行

Design and implementation of a database design aid using VP-Expert

The design and implementation of a database modeling aid called Database Designer (DBD) using VP-Expert are discussed. The DBD expert system is intended to help novice users design a proper database by asking questions of the user and thus incrementally building a structure for an extended entity relationship (ER) diagram. The authors discuss their approach to system design for DBD and implementation issues specific to VP-Expert, such as combining backward chaining and forward chaining, procedural techniques, and transparency and visibility of VP-Expert statements. This study indicates that applying a systematic, structural approach, properly commenting the code, and logically grouping rules can make an expert system programming approach viable for designing a complex procedural design application like DBD.<>
