1. A system for derivation of missing data objects from test data, the system comprising: a data populator having code for: (1) generating data objects from the test data, (2) arranging the data objects in a tree structure, (3) deriving the missing data objects from the tree structure, and (4) populating the missing data objects into the tree structure; a data model in communication with the data populator, wherein the data model stores the data objects and the missing objects generated by the data populator; and a plurality of clients in communication with the data model, wherein the clients each selectively read the data objects and the missing data objects stored by the data model.
