The RelView-System is an interactive tool for computer-supported manipulation of relations represented as Boolean matrices or directed graphs, especially for prototyping relational specifications and programs. It is developed at the Department of Computer Science and Applied Mathematics of Christian-Albrechts-University of Kiel.This Web-page describes how to get RelView and provides some further information.

News

July, 2009: After a long time of development, the new version 7.2 is out. Here is a brief overview of changes from version 7.0:

• Ported from GTK+-1.0 to GTK+-2.0.
• Added a new file format called Xdd, based on XML and BDDs. The DDD and XRV formats should no longer be used and will be removed in future versions.
• It's now possible to cancel a running evaluation.
• A simple debugger and an ASSERT() statement were added.
• Editing graphs in the GUI has been simplified.
• TRUE()/FALSE() functions were added.
• Execution of WHILE loops has been fixed.
• Various minor changes and bug fixes.

For a more detailed overview, take a look at the documentation. Downloads are available here. Version 7.2 is also installed on the local system.

• The KURE for your relational problems - The Kiel University Relation package contains the relational functions of RelView in an easy to use linkable C library. The Java library KURE-Java is an extension of the KURE library and has been developed at the Chair of Software Technology at the University of Dortmund. Currently this Java library is used to reimplement RelView as plugin for the development platform Eclipse, called RelClipse .
