General Research Issues in Multimedia Database Systems HANAN SAMET Computer Studies, Sczence Department University of Maryland, and Center for Automation Park, Maryland Research and Instztute umd.edu) for Advanced Computer College { h@@umiacs. Many of the database research issues involved in dealing with multimedia data are similar to those that arise in handling other nontraditional data such as text, document, spatial, image, temporal, and scientific. We focus here on multimedia database issues, which we hope can serve as a starting point for a wider discussion. Our examples are often taken from the spatial domain as this is where we have the greatest expertise, although these issues are far more general. Why do we want a database? The natural and simple answer is to be able to store and retrieve data efficiently. Notice the emphasis on retrieval. We should not lose sight of this purpose. For example, it means that storing images in long fields in a relational database is usually not the answer.
