Enterprise Objects Framework

Enterprise Objects Foundation (or more commonly, EOF) is an object-relational mapping product sold by NeXT for use on OpenStep. It developed from an earlier "low level" toolkit known as "DB Kit", and became a fairly widely used enterprise programming tool in the mid 1990's.

In 2000 the toolkit underwent a port to the Java language from its native Objective C. Most of the power of the toolkit was in fact a side effect of Objective C, and EOF no longer has the beauty or simplicity it once had. It is also no longer sold as a product on its own, and is contained unnamed within WebObjects.
