A multimedia database stores different types of media like text, images, audio, and video. It differs from a standard database by storing media internally rather than just text and numbers. Multimedia databases can be linked or embedded, with linked databases having smaller sizes but slower retrieval and embedded databases having larger sizes but faster retrieval. Data is stored in three parts - raw data, registering data, and descriptive data. Multimedia databases have applications in digital libraries, news, video on demand, music, maps, marketing, and more.

2. What is Multimedia
Multi
Media
Many or more than one.
Medium of Communication

3. Multimedia
In Computer,Multimedia means
that computer information can be
represented through audio,
video,and animation in addition to
traditional media

4. What is Database
 A database is a collection of information organized to provide
efficient retrieval. The collected information could be in any number
of formats (electronic, printed, graphic, audio, statistical,
combinations)
 A database could be as simple as an alphabetical arrangement of
names in an address book or as complex as a database that provides
information in a combination of formats.
 Examples:
•phone book
•address book

5. What is Multimedia Database
A Multimedia database (MMDB) is a collection of related
multimedia data. The multimedia data include one or more
primary media data types such as text, images, graphic objects
(including drawings, sketches and illustrations) animation
sequences, audio and video etc.
Multimedia database systems are
database systems where, besides text
and other discrete data, audio and
video information will also be stored,
manipulated and retrieved

6. How does it Differ from standard databases?
The difference between Multimedia databases and standard databases is a
multimedia database stores information and media ‘internally’ whereas a
‘normal’ database can only store textual or numerical data

7. Types Of Multimedia Database
There are two types of multimedia Database & they are as follows
•Linked Multimedia Databases:
 Multimedia database can be organized as a database of metadata(Data about data).
 This metadata links to the actual data such as graphic, image, animation, audio, sound etc.
 These data may be stored on Hard Disc, CD-ROM, DVD or Online.
 In this database, multimedia elements are organized as image, audio/ MP3, video etc.
 Advantage of this type of database is that the size of database will be small because elements are
not embedded in the database, but only linked to it.
•Embedded Multimedia Database:
 Embedded Multimedia Database implies that the database itself contains the multimedia objects as
in the binary form in the database.
 The main advantage of such kind of database is that retrieval of data will be faster because of the
reduced data access time.
 However, the size of the database will be very large

8. Data types are categorized into 3 classes
 • Static media
 • time-independent
 • image and graphic object
 • Dynamic media
 • time-dependent
 • Audio, video and animation
 Dimensional media
 • 3D game and Computer Aided Drafting (CAD) programs.

9. How data is stored in MMDBMS?
The Multimedia data can be stored in 3 parts.
They are
1. Raw Data
2. Registering Data
3. Descriptive Data
Multimedia data
Raw Data
(Uncomprssed Image)
Registering Data
(Size & coding details
of raw data)
Descriptive Data
(Textual numerical
annotations)

10. Data Structure
 • Raw Data
Unformatted Information Content i.e pixels.
 • Registering Data
Data necessary for interpretation and identification i.e. Format.
 • Descriptive Data
Information about content and structure

11. Operations on Multimedia Data
The operations are
 1. Input
 2. Output
 3. Modification
 4. Deletion
 5. Comparison
 6. Evaluation

12. Advantages:
 They support multiple formats of datas (text, audio, video etc)
 Data independence: Separate the database and the management from the
application program.
 They provide access and authorization control.
 Query support :Multimedia databases should have the ability to uniformly Query
data (media data, Textual data) represented in different formats and have the
ability to simultaneously query different media sources and conduct classical
database operations across them
Disadvantages:
 Usually, the data size of multimedia is large such as video; therefore, multimedia
data often require a large storage.
 Multimedia database consume a lot of processing time, as well as bandwidth
Advantages and Disadvantages of MMDatabase

13. Application of Multimedia Database:
 Digital Libraries
• Documentation and keeping Records
• Knowledge distribution
• Education and Training
 News-on-Demand
• Advertisement
 Video-on-Demand
• Entertainment
 Music database
 Geographic Information System
 Marketing
 Reverse Image searching
 Web albums
 Public protection:
 Real time control and monitoring
 Medical information system

14. Conclusion:
 Multimedia content becomes more and more
popular.
 A database is something that holds and
organizes data in a way that makes it easy to
retrieve and allow a user to search for a particular
record.
 A multimedia database allows text, data, video,
still image, dynamic image and audio to become
integral parts of database management- and this is
a consequence of information retrieval.
