Case Study Object Oriented Database

Ayoub, Georges (1998) Object-oriented database management system case study for declarative query language. Other thesis, Concordia University.

Abstract

Object-Oriented database management systems (OODBMS) combine the abstraction power of objects with the query and performance capabilities of database management systems. Existing query notations were missing many object related features until recently. The introduction of a new query notation, known by Object Comprehensions, allows queries to be expressed clearly and processed efficiently. Our work is to establish a testbed for the processing of Object Comprehension Language (OCL) queries using an experimented object-oriented database, Ode. This thesis overviews object-oriented databases evolution, and object query processing, then introduces an object-oriented database system, Ode, whose programming language O$\sp{++}$ is based on C$\sp{++}.$ A university data model is built using O$\sp{++},$ stored into the Ode database, and utilities, such as bag, list and set, are written to support the processing of OCL queries. The translation of OCL queries into O$\sp{++}$ is not part of this thesis, but is part of a related project.
