ODEPSI is an experimental object-oriented data base management system. Developed as an extension to Smalltalk-80 (trademark), ODEPSI is currently designed for the management of design and construction project data. ODEPSI represents and manages data items on the basis of the object-oriented paradigm; all data items are in objects, and each object has a set of properties and related procedures. The current version of the system emphasizes automatic constraint enforcement and semantic modeling. ODEPSI provides facilities for defining and maintaining constraints on property values, object types, and object relationships. Semantics, which imply the meaning of the real-world subject being modeled, are represented through the use of object properties and interobject relationships. Major system components of the current version include a data definition language and a data manipulation language. ODEPSI is an acronym for Object-oriented data base management system for DEsign and Project planning and control System Integration.
