Data Mining Query Scheduling for Apriori Common Counting

In this paper we consider concurrent execution of multiple data mining queries. If such data mining queries operate on similar parts of the database, then their overall I/O cost can be reduced by integrating their data retrieval operations. The integration requires that many data mining queries are present in memory at the same time. If the memory size is not sufficient to hold all the data mining queries, then the queries must be scheduled into multiple phases of loading and processing. We discuss the problem of data mining query scheduling and propose a heuristic algorithm to efficiently schedule the data mining queries into phases.
