The goal of this web site is to remember and share the ideas, vision and articles of Johan ter Bekke. He has contributed a lot to the research of data modeling principles, data language design, database management systems and end user computing.

The main results of his work can be summarized as follows:

• A new data modeling approach based on semantic principles resulting in inherently specified data structures.
• A new and efficient data language (more suitable for end users than SQL) respecting data structure and avoiding the (join) pitfalls of SQL.
• The implementation of semantic modeling and manipulation concepts in the
  Xplain DBMS.

This site is created and maintained by ex-TU Delft colleagues of Johan ter Bekke: Bert Bakker, Martin van Dinther and Berend de Boer.
