Visuelle Datenbankprogrammierung mittels Schemanavigation
The aim of the research project is the support of the interaction with large, complex databases. The interaction process can be optimized by the supply of relevant information by the user interface. The paper characterizes the difficulties of relational query languages. The concept of navigating interaction is presented which consists of the visualization of the database schema as in information network and the generation of SQL-statements composing relations, attributes and other parameters during the navigation through the network. The objectoriented implementation of the prototype is described and results of its evaluation are published.
