Image, Audio, and Video Extenders Administration and Programming


Chapter 1. Overview

DB2 (DB2) Universal Database (UDB) is a powerful, object-relational database manager. It stores and protects traditional numeric and character data, as well as large, complex objects (LOBs). DB2 extenders help you exploit DB2 's object-relational features. The extenders define distinct data types and special functions for image, audio, video, and text objects. By doing this, the extenders save you the time and effort of defining these data types and functions in your applications. The data types and functions are available through SQL. Because of that, the extenders give your applications a single point of access to any or all of these types of data, along with traditional numeric and character data. In addition, the extenders give your applications new ways to search for information. For example, your applications can search for images by their visual characteristics, using visual examples of color or texture.
