Multimedia database system pdf Continue The Multimedia Database (MMDB) is a set of multimedia-related data. Multimedia data includes one or more of the main types of data, such as text, images, graphic objects (including drawings, sketches and illustrations) of animated sequences, audio and video. The Multimedia Database Management System (MMDBMS) is a structure that manages different types of data potentially presented in a wide variety of formats across a wide range of media sources. It supports multimedia types and makes it easier to create, store, access, request, and manage a multimedia database. The content of MMDB A Multimedia Database (MMDB) contains one or more types of multimedia data (i.e. text, images, graphics, audio, video, animation sequences). These types of data are broadly classified into three classes: Static Media (time-free: image and graphic object). Dynamic media (depending on time: audio, video and animation). Dimensional media (3D games and computer programs for development). Comparison of multimedia types Medium elements Time dependence Text Printable characters No graphic vectors, regions No pixels without sound sound, Volume Yes Video Raster images, graphics Yes Also, multimedia database (MMDB) you need to manage additional information pertaining to actual multimedia data. Information about the following: Media data: actual data representing the object. Media format data: information about the format of media data after they go through the stages of acquisition, processing and coding. Media keyword data: keyword descriptions that normally relate to media data generation. Media function data: content-dependent data, such as color distribution, textures, and the different shapes in the image. The last three types are called metadata, describing several different aspects of media data. Media keyword data and media are used as indices for search purposes. Media data is used to present the information you receive. Requirements for multimedia databases, such as traditional databases, multimedia databases, must meet the following requirements: Integration data elements should not be duplicated for various programs citing data independence separate the database, and management from Concurrency Control application programs allows simultaneously transactions Saving data objects can be stored and reused by various transactions and programs, citing access to privacy and control authorization ensures transaction consistency. Support For Storage Request Allows it is easy to request multimedia data Multimedia databases should be able to evenly request data (media data, text text presented in different formats and have the ability to simultaneously request different media sources and conduct classic database operations through them. They should be able to get media objects from a local storage device in a good way. (Storage support) They should be able to accept the response generated by the request and develop a presentation of this response in terms of audio-visual media and be able to deliver that presentation. (Support for presentation and delivery) The issues and challenges of Multimedia Data consists of different media formats or file presentations, including TIFF, BMP, PPT, IVUE, FPX, JPEG, MPEG, AVI, MID, WAV, DOC, GIF, EPS, PNG, etc. Typically, the size of multimedia data is large, such as video; so multimedia data often requires a lot of storage. The multimedia database consumes a lot of processing time as well as bandwidth. Some types of multimedia data such as video, audio and animation sequences have temporary requirements that have implications for their storage, manipulation and presentation, but images, videos and graphics have special limitations in terms of their content.

Received from Go to the main content Go to the Content Table Reference EntryDOI: Multimedia Database Databases that contain and allow key data management operations with multimedia data. Traditional databases contained alphabetical data and managed it for various applications. Apps are now increasingly containing multimedia data that require additional types and require the development of storage, management, access, and multimedia data. Multimedia databases need to increasingly address issues related to the management of multimedia data as well as traditional data. Typically, databases that manage images, audio and video in addition to metadata related these and other alphabetical data are called multimedia databases. When databases contain only one of the images, audio or video, they are called image databases, audio databases, and video databases, respectively. Given the current trend, it is likely that most databases will gradually become multimedia databases. This is a preview of the content of the subscription, log in to check access.

The structure that manages different types of multimedia data that can be stored, delivered and used in a variety of ways is known as a multimedia database management system. There is a three-class multimedia database that includes static media, dynamic media and dimensional media. Content of a multimedia database management system : Media data - actual data representing an object. Media format data - information such as sampling speed, resolution, coding scheme, etc. about media data format after they acquisition, processing and coding phase. Media Keyword Data - Description of keywords related to data generation. It is also known as content content Data. Example: date, time and place of recording. Media function data is content-dependent data, such as color distribution, texture types, and the different shapes present in the data. Types of multimedia applications based on data management characteristics: Repository Applications - A large amount of multimedia data, as well as meta-data (media format date, MEDIA keyword data, media function data) that are stored for search purposes, such as satellite image repositories, engineering drawings, radiological scanned images. Presentation Apps - They include the delivery of multimedia data subject to time constraints. Optimal viewing or listening requires DBMS to deliver data at a certain speed, offering quality of service above a certain threshold. Here, the data is processed as it is delivered. Example: Abstract video and audio data, real-time editing analysis. Collaboration with multimedia information - it involves performing a complex task by merging drawings, changing notifications. Example: Intelligent Health Network. There are still many problems for multimedia databases, some of which are : Modeling - Working in this area can improve the database compared to the methods of finding information, so documents are a specialized area and deserve special attention. Design - The conceptual, logical and physical design of multimedia databases has not yet been fully resolved as the performance and customization issues at each level are much more complex because they consist of different formats like JPEG, GIF, PNG, MPEG, which is not easy to convert from one form to another.
