When you run a Web site, you coordinate files that contain video, audio, and graphic data. Loading and retrieving these kinds of data from the database used to be difficult and required special programming skills.
With Oracle's interMedia tool, a great deal of that specialized programming has been provided for you. Now you can use familiar PL/SQL calls to stored packages to modify or query audio, video, and graphic data formats.
The interMedia toolset includes several related components, as you can see in the MouseOver diagram below.
Inter media Components
The interMedia tool allows you to retrieve data from just about anywhere and load it into the database.
In particular, the Java client side of interMedia makes it easy for you to load images or other media data from your client's desktop into your database.
The table shows some of the useful features of interMedia.
Query attributes of image, video, or audio type data
interMedia provides methods for the object types ORDAudio, ORDVideo, and ORDImage. These methods allow you to attach comments, descriptions, height, width, length, compression type, format, and other important information about each image, video, or audio record. These attributes can be queried by using methods as well.
Get data from the database, modify it on the desktop, and replace the modified data in the database by using a Java application
The Java client for interMedia builds a copy of the media file on the desktop. If the user can update the copy, the Java client locks the database record so no one else can modify it until it has been returned.
Extend interMedia for all types of data
You can write customized subclasses and methods for the interMedia ORDMultiMedia class so that the database handles any kind of data you have.
The Visual Information Retrieval tool is related to the interMedia tool. Both can store and retrieve image files in the database using objects and methods.
The Visual Information Retrieval tool has additional query capabilities based on image content.
