    • Techniques are provided for (1) extending SQL to support direct invocation of frequent itemset operations, (2) improving the performance of frequent itemset operations by clustering itemset combinations to more efficiently use previously produced results, and (3) making on-the-fly selection of the occurrence counting technique to use during each phase of a multiple phase frequent itemset operation. When directly invoked in an SQL statement, a frequent itemset operation may receive input from results of operations specified in the SQL statement, and provide its results directly to other operations specified in the SQL statement. By clustering itemset combinations, resources may be used more efficiently by retaining intermediate information as long as it is useful, and then discarding it to free up volatile memory. Dynamically selecting an occurrence counting technique allows a single frequent itemset operation to change the occurrence counting technique that it is using midstream, based on cost considerations and/or environmental conditions.
    • 提供技术用于(1)扩展SQL以支持频繁项目集操作的直接调用,(2)通过聚类项目组合来提高频繁项目集操作的性能,以更有效地使用先前生成的结果,以及(3) 选择在多相频繁项目集操作的每个阶段期间使用的发生计数技术。 当在SQL语句中直接调用时,频繁的项目集操作可以从SQL语句中指定的操作结果接收输入,并将其结果直接提供给SQL语句中指定的其他操作。 通过对项目集合进行聚类,可以通过保留中间信息来更有效地使用资源,只要它是有用的,然后丢弃它来释放易失性存储器。 动态选择发生计数技术允许单个频繁项目集操作基于成本考虑和/或环境条件来改变它正在中游使用的发生计数技术。
