MDELite is a back-to-basics approach for teaching principles of Model Driven Engineering (MDE).  Complex Eclipse MDE tools are shunned; MDELite was created to avoid Eclipse for undergraduate software design class (as I and students had a LOT of problems using them -- problems to the point where I will never use Eclipse MDE tools again).

The ideas of MDELite are to use:

1.   Relational databases to express models and metamodels,
2.   Java streams to express and enforce metamodel constraints, and
3.   Java tools to implement M2M, M2T and T2M transformations.
