description

This paper describes a development principle and technique for a simple universal multiple database browser. The browser operates by getting information from metamodel of data sources and actual data from legacy data sources. Every element such as entity, field, and relation is mapped to some component of HTML page with appropriate structure and layout. Many templates of information layouts can be created allowing to dynamical changing of HTML page to acceptable user interface. The wrappers are used to provide browser with actual data and to act as mediators between data sources and browser. This approach allows to quickly describing new data sources, creating wrappers, making modifications later and managing data browsing in a simple unified style. The browser architecture is flexible enough to incorporate data sources with a variety of data models and query capabilities by various protocols. It is possible to select logically tied information from all available legacy data sources.
