A 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
A multidimensional database management system is a database management system that uses a data cube as an idea to represent multiple dimensions of data available to users. This database is optimized for data warehouse and analytical processing applications...

Multimedia is based on two key concepts; integration and interactivity while hypermedia is based on a relational database organisation

Very little. Graphic data is held in tables (flat files) but in general there are no relational aspects to the data. Multimedia applications can sometimes be used to access databases, but because the intent of the two are generally at odds, there is little mixing. For higher level applications (games) a connection between the interface (3d/multimedia) and the database of objects (database) is built and the programmers have to make sure they both work with each other.
The incorporation of multimedia database systems will improve the quantity and quality of information manipulated by computer users in all fields, computer aided design, and information retrieval. The area of intelligent multimedia content analysis and retrieval techniques is an emerging discipline. Techniques for representing and extracting semantic information from media such as speech, images, and video are required. When a multimedia application lacks a database, the data structure is buried in the script, where all of its value is lost. This omission also makes the script more complicated and less flexible. Using a multimedia database makes the data structure logic available to other multimedia applications and simplifies the script so that many scripts can share the same multimedia metadata. In addition, when a multimedia or abstract data database is organized and annotated for one application, other applications can use those annotations without going through the same time-consuming process. This capability adds great value to the data through reuse and controlled redundancy. When multimedia application content is controlled by the multimedia database, multimedia content can be added, deleted, or modified without modifying the application script. For example, interactive kiosks that display, describe, and demonstrate products can be updated automatically without reprogramming the application script. Furthermore, a multimedia application such as a multimedia textbook can actually control the operation of book topics that have the same look and feel. This control lets the script perform as a template: An entire series of math textbooks (algebra, calculus, trigonometry, and geometry), including text and video, can use the same multimedia application because all data is physically separate. Search and retrieval operations are critical in interactive multimedia applications; they must be equally efficient and powerful. Search and retrieval of multimedia and abstract data is challenging, but multimedia databases make it feasible through internal storage format flexibility and efficient operation. The DBMS should have significant knowledge about the data and its structure to enable powerful semantic optimizations and intelligent searches. Search and retrieval operations also give the application access to media components so that they can be dynamically and seamlessly processed when necessary. By: IBZ_BEAST
Modern databases have evolved with technology. They have gone from simply file systems to multimedia database systems. Unlike before, everything is saved in a database now.
A database typically stores structured data such as customer information, product details, financial records, and inventory levels. It can also store unstructured data like images, text documents, and multimedia files. The specific information stored on a database will vary based on the organization's needs.
Google Chrome is a multimedia application. It can run various multimedia files in it easily.
