This subject aims to enable students to extend their understanding of database systems to encompass the next generation of database systems, and be able to evaluate object-oriented database storage managers. Topics covered include current trends in database technology; OODBMS and advanced applications; object-oriented data models (semantic extensions, objects, properties, classes, inheritance, encapsulation, comparison of various data models); object-oriented query languages (access to objects, methods, SQL-like language; query languages of some popular OODBMSs); versions in OODB systems (version management and CAD/CAM/CASE, ORION data model); evolution in OODB systems; authorisation in OODB systems; query processing and navigation on OO databases (query graphs and traversal of nodes, cost model); distributed objects management; indexing techniques in OODB systems (object identifiers, swizzling); storage managers for OODB systems (comparison of storage techniques for relational DBMS and OO DBMSs, clustering techniques, case study of a few popular OO DBMS (Ontos, ORION, O2, Gemstone and similar).
