I am interested in writing a better SQL mapping tool for clojure. Because I am not convinced that simple SQL composition is effective, for various reasons. I rather have some kind of logic construct that I could use to generate SQL from. My main concern is to eliminate the hard boundary between the RDBMS and the rest of the code. Any given logic construct would a candidate to be translated into SQL or executed inside the JVM.
One option that I have been considering is a production rule system. The most popular are based on the rete algorithm. I know there are a few open source productions systems out there, but I think translating into SQL from an established rule language may be too complicated. At this point I plan to use the language extensions proposed by Anurag Acharya, that eliminate sequential guards and adds collection support. The reason is that I want to process the rules in parallel, and I want to be as close to SQL as possible. Clojure pure functions could also be called from within a production rule. The use case I have in mind is regular IT apps, not necessarily complex decision systems. I just find myself writing too much code, and often an SQL a clojure procedure and a function in the GUI will have some aspect of the same business rule embedded in the code. A layered approach helps to alleviate the problem, but it still persists. More support for declarative code may be the answer. But other than SQL or LINQ and other minor examples, there is little support for declarative code for average IT systems. Anyone has any ideas/opinions? I would appreciate any feedback.
