MOODD, a method for object-oriented database design

摘要

In this paper we propose a Method for Object-Oriented Database Design, called MOODD. Considerable recent research [22] has focused on object-oriented design techniques. MOODD distinguishes itself by generating an object-oriented data definition from requirements written in a natural language. Examples to illustrate the method are given for a particular OODBS called O2 [19]. MOODD consists of three phases. The first phase is to use a Requirement Specification Language (RSL) [27] to represent user requirements. Next, the RSL requirements are converted into an object-oriented conceptual model composed of the Nested Entity-Relationship (NER) [10]/ Update Protocol Model (UPM) [9]. Finally, the NER/UPM schemas are implemented by an object-oriented data model.
