We are proud to announce the release of version 0.98 of the modeling tool. This version has been in the making for over one year, and is already used in production for a number of data warehouses and system databases. The graphical interface, while retaining the look and feel, has been completely rewritten in animated SVG, which has improved performance and usability over the old canvas implementation. This step was necessary in order to make it easier to extend the tool graphically. The test version, now at 0.99, will make use of this in order to add support for visualising natural keys. A number of changes have also been made to the triggers, utilising nested triggers in order to reduce the size of a single trigger. Remember to disable triggers before doing inserts directly into attribute tables when you use ETL tools, rather than the triggers on the latest view.
The test version has already been given a number of fixes, primarily to align it with the current research in Anchor modeling. Among these are decisiveness, which controls whether a positor may hold multiple beliefs at a given point in bitemporal time, or if only a single belief is possible (which is the default behaviour).
