Amidst the dramatic developments of computer technology in thelast decades, we have seen a growing interest in supportingmultimedia data. Compared with traditional data, the mostnoticeable features of multimedia data are their spatiality (thespatial layout of objects and their relationships), temporality(time-dependence in media such as video and audio), andpresentation requirements (imposed in response to user queries,such as synchronization of different media). Developing databasemanagement support for multimedia data poses interestingchallenges.Many multimedia database management systems have been developedto deal with these multimedia features. However, they suffer somecommon problems: lack of generality in media modeling, lack ofprecise knowledge of spatial information, limited spatio-temporalfunctionality, ineffective query languages, and inefficient queryprocessing. The main purpose of this work is to investigate theseproblems and provide solutions. The first step of the research isto design a multimedia data model which is built upon and extendsexisting models. The proposed model is based on a temporal intervalalgebra. The establishment of a multimedia data model provides atheoretical foundation that is used to investigate multimedia querylanguages. The result is a general-purpose, object-orientedmultimedia query language which supports content-based informationretrieval. A prototype has been built to validate the proposedconcepts.
