Most commonly databases are design to manage and maintain textual and numeric data. But databases can be used to manage many other types of data such as images, videos, songs, etc. These types of databases are called Multimedia Databases. Common databases which use numeric and textual data can be retrieved using simple comparison of text- numerical values. But this method won’t be applicable for Multimedia Databases. Digitized representation of multimedia data cannot retrieve using simple methods and need to have a specific database system.
In the early stages of the computer textual and numeric data were the only data which has to handle. As computer technology developed rapidly, technologies were introduced and multimedia representation of

Introduction
Multimedia data is the main attraction of the people in modern world. They go for smart visuals rather than 1’s and 0’s. So the multimedia data become a must in developing applications and devices. And also this trend will lead to design methods which are capable of store and retrieve this kind of data. At the begging of multimedia data, it was very hard to handle because of the capacity, complexity and the structural issues in nature (Subrahmanian, 1998).
In order to handle multimedia data, multimedia database concept comes into the picture. “A multimedia database is a repository of different data objects (text, numeric values, Boolean values, dates, graphical, images, video clips, and sound files)” (Mariana Hentea 2005). As the definition describes multimedia database holds almost all the types of data known to computer systems. To handle that kind of complex set of data, complex processing and huge storage capacity needed. That is way beyond the traditional database system requirements. Multimedia information requirements are gradually growing. In near future multimedia information systems will conquer our lives and we will not be able to live without

Multimedia protector is design to protect multimedia contents against copying and tampering. In simple terms this tool protects important conference materials, software, company presentations, documents, etc from being copied or tampered. It safeguards company conference materials and documents against misuse and data theft. This tool is a commercial product (Gmbh, 2014).
3.5.1 Features Available in Multimedia Protector
This tool comes with several methods of data protecting techniques. One technique is encrypting data into a single database. So no one can access the content which are stored in multimedia protector unless you are an authorized user. Multimedia protector has its own inbuilt multimedia player and content viewer.
3.5.2 Technological Infrastructure Required
This tool is design for windows platform only. It needs a powerful PC with high RAM capacity and processing power.
3.5.3 Strength and Weaknesses
Strength:
• No programming skills are needed.

Media can be defined by its technology, symbol systems and processing capabilities. The most obvious characteristics of a medium are its technology: the mechanical and electronic aspects that determine its function and, to some extent, its shape and other physical features. (Kozma 180)
problem and it will be used in this case to build the databases. The databases
German aviator and religious leader President Dieter F. Uchtdorf stated, "It is your reaction to adversity, not the adversity itself, that determines how your life's story will develop.” In James McBride’s autobiography and memoir The Color of Water, his true self is revealed in the way he and his mother, Ruth, handled adversity. Throughout his life, James struggled to discover his true identity. Like many, he made mistakes along the way, but through the actions of his mother, Ruth, his story developed “like a Tinker toy” (McBride 270).
the mean value and the standard deviation, to represent the global characteristics of the image, and the image bitmap is used to represent the local characteristics of the image for increasing the accuracy of the retrieval system. Aptoula et al. [8] presen...
The history of the modern media surveillance systems begins first with the invention of the computer and the use of software. Before the internet, information was only transported between computers by a physical storage device or an extremely expensive network. Software for media surveillance was only used to scan the media that was available in data form for particular key words. It could then be stored and indexed to be later analyzed. (Sarlós, 1982)
By using my project one data file is converted into multimedia file of image video and audio file by cryptography and steganography. This is the most valid point in my project to accomplish the best results and this is my contribution to the field. The data of my system is collecting from different standards of cryptanalysis and used to validation of my project.
Throughout the years, it has become increasingly more efficient to access the media as more innovative and interactive mechanical devices are introduced. In fact, new technology has yet to be presented, further
As the storage capacity is dependent on the server, companies will need to install more digital storage devices and servers in order to increase the storage capacity. The company may face many constraints in the computing env...
When developing a relational database understanding the logical flow of information and proper planning will improve the probability of the database functioning the way it is intended and producing the desired results. In determining the proper structure of a relational database for a video rental store one must consider what information is stored, the process for renting videos and information on the videos maintained in inventory. Customer, Videos and Video Types are the entity classes that will be discussed and Customer Order is the intersection relation needed to explain the complete process as seen on the Entity Relationship Diagram below.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Many soft wares and tools were developed to help in storing, retrieving and processing the data, some examples of these tools
"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment
This Essay will discuss Codecs; it will explain the definition of codecs and their functions and include a brief history on digital signals, equipment and standards. It will also discuss compression and compression formats such as Lossless and Lossy and files such as FLAC and ALAC
A data dictionary is a place where the DBMS stores definitions of the data elements and their metadata. All programs that access the data in the database will work through the DBMS. It uses the data dictionary to look up the required data component structures and relationships, thus the users do not have to code such complex relationships in each program. In addition, any changes made in database structure will be automatically recorded in the data dictionary, thereby freeing the users from having to modify all the programs that access the changed structure.
Query does not uniquely identify a single object in the collection but are instead represented in the system by document surrogates or metadata. The systematic storage and recovery of data as from a file card catalogue or the memory bank of a computer. Information retrieval consists of 4 main stages identifying the exact subject of the search, locating this subject in a guide which refers the searcher to one or more documents, locating the documents, locating the required information in the documents. Entity is identified as object which is represented by information in a database. Queries which are sent by user are matched against database information. The evaluation of an information retrieval system is the process of assessing how well a system meets the information needs of its users. Information retrieval (IR) systems use a simpler data model than database systems. Information organized as a collection of
