A multimedia database management system (MMDBMS) stores and manages multimedia data like text, images, audio, and video. Multimedia data can be stored in three parts - raw data, registering data, and descriptive data. Registering data provides interpretation information, descriptive data describes content and structure, and raw data is the unformatted information content like pixels. An MMDBMS allows input, output, modification, deletion, comparison, and evaluation operations on different multimedia data types. MMDBMS design can be based on object-oriented or entity-relationship database models.

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
