Visual development of database applications

An exclusively visual approach to the development of database applications is introduced. Graphical tools and techniques are designed to represent all components of an application system, and all phases of the development process. Data, constraints, queries, transactions and programs are all expressed graphically. Analysis, design, maintenance, and even inference are carried out using graphical techniques. The visual approach is expected to be most appropriate for end users, and it is likely to encourage end-user participation in application development.
