Research Abstract |
In 1988, we began our study on fundamental operations for multi-media databases and the design of a multi-media database query language to manipulate multi-media data. In 1989, we investigated problems which arise from the interference of display objects on a screen, and proposed Semantic Overview Functions to solve these problems. In 1990, we designed a new style visual hierarchical query language which provides users with an environment to operate complex structured multi-media data and construct their semantic view hierarchies easily and freely. We also studied the retrieval and update operations to link structures which are elements of multi-media databases. The visual hierarchical query language is designed to allow users to construct complex queries which correspond to advanced forms of outputs of multi-media data. The visual hierarchical query language provides users with facilities to construct queries incrementally, modify parts of them, and change the scope of them globally. In the environment of the visual hierarchical query language, the stress of semantic structures can be moved from the side of databases to the side of users' views. In addition, databases and users' views are visualized into icons, and we can create queries and new views by directly manipulating the icons. The environment is currently being implemented on Macintos computers.
