一种演绎图象数据库模型设计

Design of a Deductive Image Database Model

本文提出了一种用Turbo Prolog 语言实现的演绎图象数据库系统模型IIDBSM,阐述了演绎图象数据库的设计及实现技术。IIDBSM 采用一种面向图象实体的扩展的关系模式并引入框架等抽象数据类型,利用Prolog 内部的演绎推理机制,用规则表示具内涵意义的事实间的演绎关系和完成对数据库的完整性约束等控制功能,从而实现了对图象信息的检索、更新、维护的一般数据库功能及推理智能等。

In this paper,we present a kind of deductive image database system model——IIDBSMand describe its design and building techniques.IIDBSM uses a pictorial object-oriented and extend-ed relational model involving some abstract data types such as frames.It utilizes the deductive andreasoning mechanism in PROLOG to express the relationship of the intented facts as rules and gua-rantees the integrity constraints and performs controlling functions with productive rules to support theretrieve,update,maintenance and other deductive database performances on image information.
