Although a reasonably experienced Java programmer, I'm completely new to Drools and am just in the process of exploring some options for my current project. Advice from practioners here would be very welcome. An existing web based b2b application allows clients to select products from the available range by selecting items from a product tree where nodes are used to group similar items. The new requirement is for and expert engine that guides the client through a series of qestions and can accept a range of parameters that describe the product (in terms such as RPM, pressure, flow rate, size, colour, etc.). The engine should then select an appropriate solution from a range of existing product or, propose a new custom product (that might actaully get designed in the fly) based on the client requirements. If no suitable solution is found, the collected data should be referred to human engineers for consideration. I had originally considered a simple Question/Answer mechanism where the Answer to a Question simply points the user to the next Question or the Solution. But this seems to lack sophistication and has difficulty when applied to questions that give rise to multi-dimensional (spatial) and multi-type (double, boolean, string etc.) answers. Can practitioners advise, is Drools a suitable solution? Or is it overkill for what is actually a reasonably simple problem? db -- View this message in context: http://drools.46999.n3.nabble.com/Is-my-project-a-suitable-candidate-for-...
