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
OODBMSDifferent medias are represented by
classes, whose instance variable include the data as internal state.
ERDBMSEmbedding new functions and types into
RDBMS.
