MMDBMS

It is not the conventional alphanumerical data.It is a collection of

Text, Image, Audio or Video.

What is Multimedia Data?

The information provided by multimedia data explains more than what a conventional data explains.

Why Multimedia Data?

A multimedia database management system is a framework that manages multimedia data. It can also do operations with those multimedia data.

What is Multimedia DBMS?

The Multimedia data can be stored in 3 parts.They are

Raw DataRegistering DataDescriptive Data

How data is stored in MMDBMS?

Descriptive DataInformation about content and structure

Registering DataData necessary for interpretation and

identification i.e. FormatRaw Data

Unformatted Information Content i.e. pixels

In MMDBMS there are different data types.They are:-

TextImageAudioVideo

Data types

Character represents RAW dataRegistering data describe the CodingDescriptive data include data about layout,

structuring.

Text

Pixels represent RAW data.Registering data include length and height of

image.Descriptive data are individual line, subject

and surfaces.

Image

Raw data contains the digital samples of audio.

Registering data contains the properties of audio coding.

Descriptive data contains the content of audio.

Audio

Pixel matrices represent the raw data.Registering data provides the number of

images per second.Descriptive data provides scene description.

Video

The operations areInputOutputModificationDeletionComparisonEvaluation

Operations on Multimedia Data

InputData will be written to the database.RAW and Registering data is mandatory.Descriptive data is optional.

OutputReads the data from database as per the

registering data.

Input & Output

ModificationChanging of RAW, Registering and

descriptive data.Deleting

Removes the entry from database.

Modifying & Deleting

ComparisonSearch and Retrieval of stored data.Pattern Matching Technique is used.

EvaluationGeneration of descriptive data from Raw

and Registering data.

Comparison & Evaluation

Design of multimedia database is based on two different DBMS.They are:-

ERDBMSOODBMS

Design of MMDBMS

classes, whose instance variable include the data as internal state.
