| Zusammenfassung: | Abstract: "While the relational query languages are declarative, they have been found to have inadequate expressive power. The query language Datalog extends the querying abilities of the relational languages. The bottom-up evaluation techniques have been developed to compute datalog queries. During bottom-up evaluation of a datalog query, many tuples become redundant, i.e., they are no longer needed for the remainder of the evaluation. The detection of redundant tuples can be useful for enhancing concurrency and memory utilization. In this thesis, we provide a framework for detecting redundant tuples during bottom-up evaluation of datalog queries. |
