Object-Oriented handle text, images, audio, video, and other objects. images and other nontext items are stored as objects with hierarchy and a navigational programming style. an object can inherit properties from another object. Mulitdimensional hybrid between heirarchical and relational. Useful for large amts of data in a short time.
