Schema updates and consistency,We develop a formal model to capture the . of method schemas, and obtain basic results on such evolutions. We use our model to obtain an algorithm for .. The algorithm is . in the sense that it avoids any redundant checking.

Aufbau der Ala-Anzeigen-Gesellschaft on Shipman‘s original Daplex language for the optimisation. The advantage of this is that it fits the navigational style of querying very well, but it is also optimisable. The optimisation is based on the equivalence of most Daplex queries to . as pointed out in ..As we developed the

We show that, the H-tree indexing scheme is indeed a general access method for the new generation DBMS that most probably will support the object-oriented concept and have the deductive capability. The simplest form of the H-tree, like the widely used ..-tree, can be

Thus, we define a construct called ., which is consistent with the fixpoint-based semantics, cures the deficiencies of the former appr
