Forward Engineering Moving from a logical data model to a physical data model. Since all dependencies, indexes, and interactions between the components of the data model are already accounted for in the design, this is a very simple task.

Reverse Engineering Making an effort to recreate the logical data model using the physical data model as a starting point. This is difficult to do because not all database engines provide the capabilities necessary to record the interdependencies that exist between items in a logical model. Moreover, there are occasions when these links are completely severed. Analyzing the data and making accurate predictions about the connections that are not at all available, is the only way to get this knowledge back.
