Multimedia Presentation Databases

1996

Advanced multimedia applications call for integrated database system support for the management of multimedia data. Traditional database management systems do not provide appropriate concepts and services for the integrated modeling, management, and interactive presentation of multimedia data. Our approach towards a multimedia database management system o ers presentation independence to applications, which is in line with traditional database system services like data independence and multiuser support. This new service is realized by the integration of appropriate concepts for continuous object management, the representation and presentation of multimedia data, and the execution of interactive end-user presentations into an open objectoriented database system. The resulting multimedia database system consists of database clients for the interactive presentation of multimedia data, which can be adapted to particular needs of applications, and a database server for the e cient management of and access to multimedia data. Chapter 1 dependent (continuous). We follow the de nition of 27] and refer with the term multimedia application to those applications which include both timedependent and time-independent media types.

temporal, storage, retrieval, integration, and presentation requirements of multimedia data differ significantly from those for traditional data. A multimedia database management system provides for the efficient storage and manipulation of multimedia data in all its varied forms. We look into the basic nature of multimedia data, highlight the need for multimedia DBMSs, and discuss the requirements and issues necessary for developing such systems.

A t the heart of multimedia information systems lies the multimedia database management system. Traditionally, a database consists of a controlled collection of data related to a given entity, while a database management system, or DBMS, is a collection of interrelated data with the set of programs used to define, create, store, access, manage, and query the database. Similarly, we can view a multimedia database as a controlled collection of multimedia data items, such as text, images, graphic objects, sketches, video, and audio. A multimedia DBMS provides support for multimedia data types, plus facilities for the creation, storage, access, query, and control of the multimedia database. The different data types involved in multimedia databases might require special methods for optimal storage, access, indexing, and retrieval. The multimedia DBMS should accommodate these special requirements by providing high-level abstractions to manage the different data types, along with a suitable interface for their presentation. Before detailing the capabilities expected of a multimedia DBMS and the requirements such systems should meet, we must first consider the characteristic nature of multimedia information. Then we can discuss the issues facing multimedia DBMSs.

Multimedia is a blend of two or more media such as text, sound, graphics, animation and video, to effectually converse ideas to the users and this could be in linear or non-linear form [7]. The application of multimedia technology to database and IT service management has improved enormously in recent times. Multimedia system is a distinctive application which is of time-critical in its use in the various areas of computing. The spatial, secular, storage, processing, recovery, grouping and management requirements of data vary momentously from those that are applied for traditional data [2]. Therefore, the purpose of multimedia technology in database management system and in proper management of IT services to clients is to permit for an efficient way of performing these tasks in all its varied forms in an efficient form. A multimedia database management system affords an efficient storage and manoeuvring of multimedia technologies in all its diverse types. Database technology has offered means to store and recover high volumes of data in the various business domains [8]. Although, database systems have always been planned for the administration of alphanumeric data such as names and numbers, the basic nature of multimedia data are also considered and thus highlights the need for multimedia enhanced database management systems, and present the various obligations and issues required for developing such systems. The various areas of applications consist of, but not limited to digital libraries (text documents, images, sound, video etc), art and entertainment, content management, journalism etc [1]. For technology purposes, multimedia is a computer-based systems that apply associative relationships to allow the users of such systems to navigate and retrieve various information that are stored in a location which could be a combination of text, sounds, graphics, video, and other media formats [12].

Multimedia Database Security is a challenging concept in Database Management Systems. The use of Multimedia DBMS technology has increased terrifically over the last few years on the web as well as in several software applications. A multimedia communication system facilitates basic functions of Multimedia Database i. e. generation of multimedia data, its storage, and management, distribution, receiving, consuming, editing, and sharing, and so on. In this paper the different issues related to Multimedia Database Management System (MMDBMS) have been discussed. The challenges discussed by each paper reviewed in the field of Multimedia Database Management Systems have been analyzed. An empirical analysis has been done in the end to compare the issues stated by each author in literature. Due to this analysis it will help the technical people and research workers to avoid the indicated challenges while working in the field of Multimedia Database Management System (MMDBMS).

We have studied a mechanism for creating multimedia presentation from various multimedia objects such as video, image and text. The important points for creating multimedia presentation are specification and verification. Specification means representation for temporal relations among multimedia objects. Temporal relations specify the flow of multimedia presentation in space and time. As for verification, we should consider both syntactic and

We have extended the canonical relational data model to enable the management of multimedia objects. In an attempt to provide a smooth paradigm shift to multimedia information system development, we have enhanced the relational data model framework with techniques for modeling, storing and manipulating multimedia data. In particular, we have provided a graphical conceptual model for structuring a multimedia document and mapping rules for translating it into an extended relational data schema. Extensions have regarded the management of foreign keys, active components, mechanisms for the management of spatial and temporal relations, and finally functions for handling multimedia presentations. As a consequence, we have also provided extensions to the SQL language to handle these new mechanisms.
