i've been trying to write it so the core system doesn't need to know anything about the layers on top of it, and that each "plugin" has its own connection string, exposed methods, and imbedded views, so anything being added later only has to know about the data upon which it's dependent, but knows nothing about the plugins dependent upon it.
each "entity" will have its "entityID" and also a "subID" to use when talking directly to a plugin (type "people", for instance, would have a "subID" that points to a PK in the "People" database.)
really, my questions are: "can you see any security concerns?" and "does anybody on slashdot have any insights when it comes to building programs agnostically (bottom up)?" and "this seemed like an obvious relationship system to me, but i can't find any examples like mine, which leads me to think there are reasons why something like this doesn't work. is this inefficient? is it fundamentally flawed?"
my base application is built around http://mvcpluginframework.codeplex.com/
lets run with the idea of eliminating unnecessary subjects from degree programs, though (just to see how much actual education we can strip out of college)... for a CS degree, why require english? or history? these have nothing to do with the actual logic, math, and engineering principals that go into designing a program or computer system. you don't need to know that Napoleon had a hard time fighting a ground war in russia in the winter (duh) or that he thought alexander the great was, well, great. you don't have to know about the allegories in the works of twain or be able to discourse on the underlying message of hamlet to be a good programmer.
unfortunately for you DO need algebra for political science if you're going to continue to call it science.
From wikipedia: "Political science is a social science discipline concerned with the study of the state, government, and politics. Aristotle defined it as the study of the state. It deals extensively with the theory and practice of politics, and the analysis of political systems and political behavior. "
so unless they're all just sitting around and talking about it they're gonna need statistics and good luck learning statistics if you can't handle college level algebra.
