    ABSTRACT

    Multimedia database is the most popular and widely used

    data in the IT sector known for data storage and retrieval

    due to technological advancement mobile computing and

    multimedia database has developed. This paper gives the

    idea and general overview of multimedia database their

    issues of multimedia database systems considering new

    area of Cloud Computing. Different types of multimedia

    databases their queries and to retrieve the data from

    database. Different types of architecture of multimedia

    databases are also discussed. Paper cover all the basic

    concepts of multimedia database. Mobile cloud computing

    is one of mobile technology trends in the future since it

    combines the advantages of both mobile computing and

    cloud computing, thereby providing optimal services for

    mobile users.

    INTRODUCTION

    Multimedia database is a database that hosts one or more

    primary media file types such as .txt (documents), .jpg

    (images), .swf (videos), .mp3 (audio), etc. and loosely fall

    into three main categories:

    Static media (time-independent, i.e. images and handwriting)

    Dynamic media (time-dependent, i.e. video and sound bytes)

    Dimensional media (i.e. 3D games or computer-aided drafting programs- CAD)

    All primary media files are stored in binary strings of

    zeros and ones, and are encoded according to file type.

    The term "data" is typically referenced from the computer

    point of view, whereas the term "multimedia" is

    referenced from the user point of view.

    TYPES OF MULTIMEDIA DATABASES

    There are numerous different types of multimedia

    databases, including:

    a) The Authentication Multimedia Database (also known as a Verification Multimedia Database, i.e.

    retina scanning), is a 1:1 data comparison

    b) The Identification Multimedia Database is a data comparison of one-to-many (i.e. passwords and

    personal identification numbers.

    c) A newly-emerging type of multimedia database, is the Biometrics Multimedia Database; which

    specializes in automatic human verification based

    on the algorithms of their behavioral or

    physiological profile.

    This method of identification is superior to traditional

    multimedia database methods requiring the typical input

    of personal identification numbers and passwords due to

    the fact that the person being identified does not need to

    be physically present, where the identification check is

    taking place. This removes the need for the person being

    scanned to remember a PIN or password. Fingerprint

    identification technology is also based on this type of

    multimedia database.

    COMPONENTS OF A MULTIMEDIA

    SYSTEM:

    The Hardware and Software Components required for a

    multimedia system are:

    (a) Capture a device which has a wide variety of range

    including Video Camera, Video Recorder, Audio,

    Microphone, Keyboards, mice, graphics tablets, 3D

    input devices, tactile sensors, VR devices.

    Digitizing Hardware etc.

    (b) Communication Networks includes Local Networks,

    Intranets, Internet, Multimedia or other special high

    speed networks.

    (c) Storage Devices such as Hard disks, CD-ROMs,

    DVDROM, etc.

    (d) Display Devices like CD-quality speakers, HDTV,

    SVGA, Hi-Resolution monitors, Color printers etc.

    (e) Computer Systems like Multimedia Desktop

    machines, Workstations, MPEG/ VIDEO/DSP

    Hardware etc.

    DIFFICULTIES INVOLVED WITH

    MULTIMEDIA DATABASES

    The difficulty of making these different types of

    multimedia databases readily accessible to humans is:

    a) The tremendous amount of bandwidth they consume;

    b) Creating Globally-accepted data-handling platforms, such as Joomla, and the special

    considerations that these new multimedia database

    structures require.

    c) Creating a Globally-accepted operating system, including applicable storage and resource

    management programs need to accommodate the

    vast Global multimedia information hunger.

    d) Multimedia databases need to take into accommodate various human interfaces to handle

    3D-interactive objects, in an logically-perceived

    manner (i.e. SecondLife.com).

    e) Accommodating the vast resources required to utilize artificial intelligence to it's fullest potential-

    including computer sight and sound analysis

    methods.

    f) The historic relational databases (i.e the Binary Large Objects BLOBs- developed for SQL

    databases to store multimedia data) do not

    conveniently support content-based searches for

    multimedia content.

    This is due to the relational database not being able to

    recognize the internal structure of a Binary Large Object

    and therefore internal multimedia data components cannot

    be retrieved.

    Basically, a relational database is an "everything or

    nothing" structure- with files retrieved and stored as a

    whole, which makes a relational database completely

    inefficient for making multimedia data easily accessible to

    humans.

    In order to effectively accommodate multimedia data, a

    database management system, such as an Object Oriented

    Database (OODB) or Object Relational Database

    Management System (ORDBMS). Examples of Object

    Relational Database Management Systems include

    Odaptor (HP): UniSQL, ODB-II, and Illustra.

    The flip-side of the coin, is that unlike non-multimedia

    data stored in relational databases, multimedia data cannot

    be easily indexed, retrieved or classified, except by way of

    social bookmarking and ranking-rating, by actual humans.

    This is made possible by metadata retrieval methods,

    commonly referred to as tags, and tagging. This is why we

    can search for dogs, as an example, and a picture comes

    up based on your text search tem. This is also referred to a

    schematic mode. Whereas doing a search with a picture of

    a dog to locate other dog pictures is referred to as

    paradigmatic mode.

    However, metadata retrieval, search, and identify methods

    severely lack in being able to properly define uniform

    space and texture descriptions, such as the spatial

    relationships between 3D objects, etc. The Content-Based

    Retrieval multimedia database search method (CBR),

    however, is specifically based on these types of searches.

    In other words, if you were to search an image or sub-

    image; you would then be shown other images or sub-

    images that related in some way to your the particular

    search, by way of color ratio or pattern, etc.

    MOBILE CLOUD COMPUTING AS A

    FUTURE OF MOBILE MULTIMEDIA

    DATABASE

    Cloud computing (CC) has been widely recognized as the

    next generations computing infrastructure offers some

    advantages by allowing users to use infrastructure (e.g.,

    servers, networks, and storages), platforms (e.g.,

    middleware services and operating systems), and

    softwares (e.g., application programs). Most of Mobile

    devices (smartphone, mobiles, tablet pcs, etc) are

    increasingly becoming an essential part of human life as

    the most effective and convenient communication tools

    not bounded by time and place.

    Mobile users accumulate rich experience of various

    services from mobile applications (e.g., iPhone apps,

    Google apps, etc), which run on the devices and/or on

    remote servers via wireless networks. The rapid progress

    of mobile computing (MC) becomes a powerful trend in

    the development of IT technology as well as commerce

    and industry fields. However, the mobile devices are

    facing many challenges in their resources (e.g., battery

    life, storage, and bandwidth) and communications (e.g.,

    mobility and security) . The limited resources significantly

    impede the improvement of service qualities.

    According to the latest study from Juniper Research, the

    market for cloud-based mobile applications will grow

    88% from 2009 to 2014. The market was just over $400

    million this past year, says Juniper, but by 2014 it will

    reach $9.5 billion.

    MOBILE MULTIMEDIA CHALLENGES

    Multimedia data are consists of images, audio, text and

    video it requires large amount of storage and fast speed

    for transferring data. For storing and managing data

    different types of devices and equipments are required in

    heterogeneous mobile environment. Data retrieval and to

    providing multimedia content to mobile devices are

    frequent device disconnection as in mobile environment

    connection breaks frequently that leads to the issue of

    synchronization and con
