Algorithms for Rewriting Aggregate Queries Using Views Algorithms for Rewriting Aggregate Queries Using Views Algorithms for Rewriting Aggregate Queries Using Views Algorithms for Rewriting Aggregate Queries Using Views
Queries involving aggregation are typical in database applications. One of the main ideas to optimize the execution of an aggregate query is to reuse results of previously answered queries. This leads to the problem of rewriting aggregate queries using views. Due to a lack of theory, algorithms for this problem were rather ad-hoc. They were sound, but were not proven to be complete. Recently we...
متن کاملRange-Aggregate Proximity Queries
In a range-aggegate query problem we wish to preprocess a set S of geometric objects such that given a query orthogonal range q, a certain intersection or proximity query on the objects of S intersected by q can be answered efficiently. Although range-aggregate queries have been widely investigated in the past for aggregation functions like average, count, min, max, sum etc. there is little wor...
متن کاملAggregate Reverse Rank Queries
Recently, reverse rank queries have attracted significant research interest. They have real-life applicability, such as in marketing analysis and product placement. Reverse k-ranks queries return users (preferences) who favor a given product more than other people. This helps manufacturers find potential buyers even for an unpopular product. Similar to the cable television industry, which often...
متن کاملIntegrity Checking for Nested Transactions
In this paper, we present a mechanism to specify and to validate consistency constraints in object oriented databases. Constraints are speciied using pre and post-conditions associated with an exception handling mechanism. During transaction run-time, we treat exceptions corresponding to errors (in this case, we use immediate exceptions which are processed immediately) or presumption of errors ...
متن کاملIntegrity Checking for Uncertain Data
The uncertainty associated to stored information can be put in direct correspondence to the extent to which these data violate conditions expressed as semantic integrity constraints. Thus, imposing and checking such constraints provides a better control over uncertain data. We present and discuss a condition which ensures the violation tolerance of methods for integrity checking. Usually, such ...
