PROLOGA 5.5 is the latest version of the Prologa toolkit.

New in 5.5

  This requires GraphViz. The decision table is shown in JPG or SVG format.
  You will need an SVG Viewer (e.g. Adobe SVG viewer).
   
• Export to RuleML, Jess(ML)
   
• Import from Weka and Antminer+
  Use rule output from these data mining tools in order to visualize the decision table
   
• Consultation environment for single tables.

• The internal format of saving decision tables (cf. tab-file extension)
  has been replaced by a new xml-based format.
   
• New limits
  It is now possible to add 12 conditions, 26 condition states per condition, 50 actions and 255 rules.
   
• Support for specifying various properties (e.g. explanation notes,
  implementation, ...) of condition and action attributes has been improved.
  A new tree-based user interface has been provided for this purpose. Also,
  the supplied information is being increasingly integrated throughout
  Prologa (e.g., implementation data are now used by code export routines,
  when provided).

• Manipulating States
  One can now add and reorder condition states, even when the condition is used in a rule. A Condition state can also be deleted, but only when it is not used in a rule and the rules are simple enough to update (no negations).
   
• A new button has been introduced to show different parts of the decision table.

New in 5.2

• Improved consultation environment
  Dockable windows have been included in the consultation environment,
  to improve its customizability. Also, parts of the original engine have

  one can now import a table from or export it to this new file format.

• View as Tree

One can now view decision tables in a hierarchical tree format (using the upperleft button in the decision table editor window). 

New in 5.0

Besides a totally re-written project core and a complete component based build-up of the program, a lot of other changes have taken place:

• A completely re-analyzed and re-written project engine, which allows intelligent project management, automatic argument connection and multiple table views so you can edit the same table on several forms!
• A new and revolutionary connection with the database, so you can work up to a 100x faster!!!
• A totally redesigned user interface.  The customizable tableforms allow you to edit and create decision tables in a very efficient manner.
• Import from MS Excel.  Now it is possible to import the tables you designed in MS Excel directly into Prologa.
• A Preview version of the Fuzzy Decision Table Editor and the Fuzzy Consultation have been included as well.
• The possibility to cut, copy and paste entire condition subjects and action subjects, including additional project information, multimedia collections etc...
