DATABASE REQUIREMENTS FOR DISTRIBUTED MULTIMEDIA SYSTEMS

Resumo

Databases have been supporting many classes of applications with very distinct requirements. Multimedia is one class of application that has been receiving a fair amount of attention lately, with lhe increasing processing power of computational systems. Databases and multimedia come together when lhe multimedia application requests storage of or access to multimedia data. However, database-related requirements of multimedia, applications are yet to be completely understood and fulfilled. This paper presents a set of requirements that must be provided by a database system in order to support the representation, storage, and manipulation of multimedia documents. These requirements provide guidelines to evaluate the adequacy of database systems for supporting multimedia applications. The main focus is on distributed systems, which reflects lhe trend towards the future of multimedia systems, whose needs could hardly be provided by stand-alone systems.
