2.  It is not the conventional alphanumerical data.
 It is a collection of
 Text,
 Image,
 Audio or
 Video.

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

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

5.  The Multimedia data can be stored in 3 parts.
 They are
 Raw Data
 Registering Data
 Descriptive Data

6.  Descriptive Data
 Information about content and structure
 Registering Data
 Data necessary for interpretation and identification i.e.
Format
 Raw Data
 Unformatted Information Content i.e. pixels

7.  In MMDBMS there are different data types.
 They are:-
 Text
 Image
 Audio
 Video

8.  Character represents RAW data
 Registering data describe the Coding
 Descriptive data include data about layout, structuring.

9.  Pixels represent RAW data.
 Registering data include length and height of image.
 Descriptive data are individual line, subject and surfaces.

10.  Raw data contains the digital samples of audio.
 Registering data contains the properties of audio coding.
 Descriptive data contains the content of audio.

11.  Pixel matrices represent the raw data.
 Registering data provides the number of images per
second.
 Descriptive data provides scene description.

12.  The operations are
 Input
 Output
 Modification
 Deletion
 Comparison
 Evaluation

13.  Input
 Data will be written to the database.
 RAW and Registering data is mandatory.
 Descriptive data is optional.
 Output
 Reads the data from database as per the registering
data.

14.  Modification
 Changing of RAW, Registering and descriptive data.
 Deleting
 Removes the entry from database.

15.  Comparison
 Search and Retrieval of stored data.
 Pattern Matching Technique is used.
 Evaluation
 Generation of descriptive data from Raw and
Registering data.

16.  Design of multimedia database is based on two different
DBMS.
 They are:-
 ERDBMS
 OODBMS

17.  OODBMS
 Different medias are represented by classes, whose
instance variable include the data as internal state.
 ERDBMS
 Embedding new functions and types into RDBMS.

18.  Libraries
 Educational Institutions
 Reverse Image searching
 Web albums

19. • optimized storage
• efficient access
• complex search is also possible
• transaction protected multiuser mode
• recovery
