Schema Refinement and: Transcript

Normal Forms Given a design how do we know it is good or not What is the best design Can a bad design be transformed into a good one Conceptual design Schemas ICs Normalization A relation is said to be in a particular normal form if it satisfies a certain set of constraints.

In a refinement based approach it is beneficial to model systems . abstractly . with . little architectural structure . We cannot complete that refinement due to a little problem: in order to get the new values and , we need not only the values of and just produced by the recursive call, , which was not sav Gordon Dunsire.
