6. Object Oriented Database Management Systems (OODBMS) An OODBMS is the result of combining object oriented programming principles with database management principles. An OODBMS is a full-scale object oriented development environment as well as a database management system. Features that are common in the RDBMS such as transactions, the ability to handle large amounts of data, indexes, deadlock detection, backup and restoration features and data recovery mechanisms also exist in the OODBMS. In OODBMS accessing objects in the database is done in a transparent manner such that interaction with persistent objects is no different from interacting with in-memory objects. This is very different from using an RDBMS. In that there is no need to interact with SQL nor is there a reason to use a Call Level Interface such as ODBC, ADO or JDBC. Database operations typically involve obtaining a database root from the OODBMS which is usually a data structure like a graph, vector, hash table, or set and traversing it to obtain objects to create, update or delete from the database. There are concepts in the relational database model that are similar to those in the object database model. A relation or table in a relational database can be considered to be analogous to a class in an object database. A tuple is similar to an instance of a class but is different in that it has attributes but no behaviors. A column in a tuple is similar to a class attribute except that a column can hold only primitive data types while a class attribute can hold data of any type. In OODBMS it is possible to have a large class, which holds many medium sized classes, which themselves hold many smaller classes. In a relational database this has to be done either by having one huge table with lots of null fields or via a number of smaller, normalized tables which are linked via foreign keys. A join has to be performed every time. Also an object is a better model of the real world entity than the relational tuples with regards to complex objects. The fact that an OODBMS is better suited to handling complex, interrelated data than an RDBMS means that an OODBMS can outperform RDBMS. The ODMBS require less code to develop, reduced development time, and reduced maintenance costs Object Store, Objectivity, Shore and Versant are some of the popular OODBMS. 7. OODBS in Digital Library OODBs provide better support and higher performance for hierarchical and complex objects. OODBs play a major role in the development of wide variety of target applications including hardware and software CAD systems, persistent programming languages, geographic information systems, satellite data repositories, digital library and multi-media applications. In a digital library OODB can be used for document analysis in multivalent document architecture, in using computer vision to extract content from images for indexing and retrieval. OODB In digital library can play a major role in the development of multimedia applications. Text reports and scientific data can be subjected to data mining using OODB applications to extract knowledge, which would help in decision-making. 58
Multimedia databases include video, images, audio and text media. They can be stored on extended object-relational or object-oriented databases. Multimedia is characterized by its high dimensionality, which makes data mining even more challenging. OODBs can be used in content-based search and video retrieval from digital libraries over computer networks. 59
