Integration of information retrieval and database management in support of multimedia police work

Abstract

DataBase Management Systems (DBMSs) are a major component of most information systems (ISs). The relational DBMS is nowadays by far the most widely accepted DBMS, although many large non-relational DBMSs are still in use, and Object Oriented DBMSs are developing. Besides, more and more DBMSs are supporting basic multi media storage and retrieval facilities. Nevertheless, advanced information retrieval facilities, especially for accessing large document and text databases, are still the almost exclusive domain of Information storage and Retrieval Systems (IRSs). A growing need is identified to integrate the facilities of a DBMS and an IRS in order to fully support work with multi ple data types, like multimedia police work. For Dutch police departments, a criminal investigation system is devel oped, fully integrating both types of facilities.
