Multimedia database management-requirements and issues

1990

Current conventional Database Management Systems (DBMS) manage only alphanumeric data. However, data to be stored in the future is expected to include some multimedia form, such as images, graphics, sounds or signals. The structure and the semantics of the media data and the operations on that data are complex. It is not clear what requirements are needed in a DBMS to manage this kind of data. It is also not clear what is needcd in the data model to support this kind of data; nor what the user interface should be for such a system. The goal of the Multimedia Database Management System project in the computer science department of the Naval Post Graduate School is to build into a Database Management System (DBMS) the capability to manage multimedia data, as well as the formatted data, and define operations on multimedia data. This thesis, focusing only on the media data of image and sound, first describes the operations of such a system, then discusses the general design of it, and finally outline the detailed design and implementation of the retrieval operation. 20 Distribution/Availability of Abstract 21 Abstract Security Classification [N unclassified/unlimited 1 same as report [] DTIC users Unclassified "2a Nam-c of Responsilc lndh idual 22b Telephone (Include Area code} 22c Office S. mbol Vincent Y.

In this article we point out important functionality needed to support advanced multimedia applications by a database management system. We introduce a generic datatype to support the implementation of time-dependent media like audio, video, and animation. Besides the demand for speci c multimedia datatypes we sketch a taxonomy for the modeling of meta information. Multimedia presentations are made independent from formats and devices similar as data are made independent from physical storage.

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).

Abstract This paper discusses a general framework for multimedia DBMSs. We use our two ongoing multimedia projects (a SGML/HyTime DBMS and an image DBMS) as examples to support the general framework. Although multimedia data (text, sound, image, video and animation) are di erent in terms of their processing, similarities exist in the ways to handle these data. They all are big with complex structures and semantics. The semantics have to be extracted, stored, and indexed to allow content-based queries.

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.

The object-oriented paradigm represents one of the most successful paradigms in many areas of computer science. It has gained wide acceptance as a unifying paradigm for the design of database systems, programming languages, and artificial intelligence area over the last decade. In this work the characteristics of the object model of data are presented. The general characteristics are described of the object-oriented database management system CODAS implemented as a library of C++ classes. The major requirements to the file architecture are formulated. The organisation of the database nodes and the structures of the object and index files are presented in details.

A MultiMedia DataBase Management System (MMDBMS) must provide facilities to store, model and query multimedia data. In the context of the STORM project 1 , we are developing an object-oriented client-server MMDBMS which addresses these problems. We use an object-oriented approach to develop reusable components which can be easily integrated in the general framework of multimedia database applications. In this paper, we present the main functionnalities of our system and we focus on video objects and their integration in multimedia presentations.

We propose a partition of the conceptual schema of multimedia databases according to the di erent aspects of multimedia data. (1) In a multimedia type schema the speci c characteristics of multimedia data are modelled but a homogeneous interface utilizing polymorphism is used. (2) A device schema makes applications independent from low level aspects of multimedia presentation devices and import or export from and to external environments. (3) An interaction schema allows interactive manipulation of presented multimedia data. The requirements of managing multimedia data in a database system like storage of high volume data and time-dependent presentation lead to support speci c built-in functionality. This is also re ected in a new architecture currently under development using the object-oriented database management system VODAK designed and implemented at GMD-IPSI. The proposed partition provides a high degree of exibility for extending the database system and designing multimedia applications. By making types describing devices and interaction tools part of the database schema, interactive queries can be supported by the database system.

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].

EVA is a multimedia database system capable of storage, retrieval, management, analysis and delivery of objects of various media types, including text, audio, images and moving pictures. The interface language deals with the temporal and spatial aspects of multimedia information retrieval and delivery, in addition to the usual capabilities provided by the ordinary database languages. EVA has five classes of operations, namely: operations for querying and updating (i.e. editing) the multimedia information, operations for screen management, temporal operators, operators for specifying rules and constraints, and aggregation (computational) operators. EVA, an extension of the query language Varqa, is a functional language whose notation is based on that of conventional set theory. It is formally defined in an algebraic framework. EVA is object oriented and supports objects, object classes, attributes and methods of objects, and relationships between objects. The current implementation of EVA runs on several different platforms.

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.
