Hi there, I said I'll help someone I know, being more familiar than him with open source, but apparently I am a bit out of my domain here, having spent 6 hours already scouring the net to no avail.
What I am looking for is an open source application that is web based, platform independent and that if it is database centric then should support either MySQL or PostgreSQL The type of project I'm after is a decision support system that also models the processes supporting those decisions. The end result is a report / document, so it should have, or be able to be integrated with, a reporting system. Final format is desirable to be PDF. The way the system should work is that it should have at its base an organisational unit that will group a set of processes. The system should be able to handle multiple such organisational units. A process will have as input a collection of variables of various types (numeric, binary, linguistic, classifications, ranges, sets, single and multi-choice selections, etc) that are associated through various rules (arithmetic, logic, aggregation, concatenation, if-then-else, simple or weighted association, etc, including user defined e.g. 2+3=6 and "because I say so"). The output of a process should be a set of variables having a valid combination of values - again, defined by the user. The output variables should be of types as varied as the input variables. These output variables can be part of an input set for another process. Circular references are ok if the system allows them. The variables and the association rules will be defined by the user through the web interface. The system is desired to handle an unlimited number of variables (200 - 1000) and an equally unlimited number of processes (100 - 500), preferable through a graphic interface. The end result is desired to be a set of reports, as in documents, made of templates chosen based of values of certain variables and will also contain variable values in themselves. To give you an ideea of what I'm talking about think http://software.typodemon.com/Wizard-Toolkit/ with a way more complicated story and a vastly richer set of conclusions. Is there such a project out there, or my buddy should start rolling up his sleeves (or more precisely his team's) and start programming. Thank you in anticipation, Adrian P.S. I over-used the world SHOULD as per http://en.wikipedia.org/wiki/Product_requirements_document but according to this convention I should have used MUST instead, to better describe what I'm talking about.
