摘要： Techniques are provided for enabling execution of a process employing a cache. Method steps can include obtaining a first probability of accessing a given artifact in a state Si, obtaining a second probability of using a predicate from a current state Sc in the state Si, determining a benefit of prefetching the given artifact using the predicate based on at least the first probability and the second probability, and whether and/or when a cache replacement should be conducted, based at least on the benefit determined.

摘要： Systems and methods for conducting attribute-based queries over a plurality of objects using bounded memory locations and minimizing costly input and output operations are provided. A plurality of attributes are associated with each object, and a plurality of data groups, one each for the identified attributes are created. The objects associated with the attributes are placed into the appropriate data groups, and the objects contained within each data group are sorted into blocks such that each block within a given attribute contains that objects having the same attribute value. Results to the query are created by loading blocks into a primary memory location in a middleware system and combining the loaded blocks to create the desire query results. Block combinations are created based upon the fit of the given block combination to the query as expressed in an aggregation function. A second dedicated memory location can also be provided to hold multiple block combinations to optimize the order in which blocks are loaded and combined. Empty block buffers and external storage devices can also be provided to further enhance the generation of query results.
摘要翻译：提供了使用有限存储器位置对多个对象进行基于属性的查询并最小化昂贵的输入和输出操作的系统和方法。多个属性与每个对象相关联，并且创建多个数据组，每个数据组各自用于所识别的属性。与属性相关联的对象被放置到适当的数据组中，并且每个数据组中包含的对象被排序成块，使得给定属性中的每个块包含具有相同属性值的对象。通过将块加载到中间件系统中的主存储器位置并组合加载的块以创建期望查询结果来创建查询的结果。基于给定块组合对于在聚合函数中表达的查询的拟合来创建块组合。还可以提供第二专用存储器位置以保持多个块组合以优化块被加载和组合的顺序。还可以提供空块缓冲区和外部存储设备，以进一步增强查询结果的生成。

The method includes receiving at least one nonstationary data stream with time dependent data. Calculating, for a given instant of sub-space of time, A set of first-moment statistical values is calculated, for a given instant of sub-space of time, for the data. The first moment statistical values include a principal component for the sub-space of time. The data is perturbed with noise along the principal component in proportion to the first-moment of statistical values so that at least part of a set of second-moment statistical values for the data is perturbed by the noise only within a predetermined variance.

摘要： A method of utilizing one or more hints for query processing over a hierarchical tagged data structure having a plurality of nodes in a computing system having memory, the hint being positive if there is a tag accessible in top-down traversal from a child node, and otherwise negative. For each tag in the data structure, the method calculates a bitmap for a current node with all bits set to 1 and for each child node, followed by AND-ing all child bitmaps and setting a bit corresponding to a tag ID of a current tag to zero if such current tag exists. The method further sets a bit of a current tag to 0, calculates a plurality of possible non-redundant hints for each child node, and refreshes a hint list.
