- W166664441 abstract "In this dissertation we developed a system, INT-AID: THE INTELLIGENT AID FOR RELATIONAL DATABASE CONSTRUCTION. It is an intelligent interactive system that aids the relational database systems designers in constructing a good design. We defined a workable methodology by integrating a wide variety of algorithms, theories, and techniques in one system. The system uses a set of Functional Dependencies (FDs) to construct relations in Third Normal Form (3NF) following the Synthetic Approach in relational database design.We proposed a novel methodology in deriving and generating a set of functional dependencies. Unlike the standard conventional method which uses structured analysis techniques to build a set of FDs; our approach is an unstructured method that does not depend on structured analysis. This new method suits the evolutionary approach in database design. In our approach we deal with an incoherent body of data, that contains many unrelated and unstructured facts. From this body of data we want to let the natural relationships emerge dynamically, rather than imposing unnatural relationships on the data. As a result of this we might uncover some hidden relationships that were not known before. This new approach is an attempt towards the establishment of causal effects. We developed a formula using mathematical induction, to give the total number of what we called proposed FDs (their validity is yet to be determined).The Synthetic Approach, which we followed in our system to construct 3NF relations, does not always produce relations that are lossless with respect to the join operation. To overcome this shortcoming we added an algorithm to check whether the synthesized relations are lossless with respect to join or not." @default.
