    摘要： There is disclosed a method and a system for generating an annotated search index. The method is executable at a server. The method comprises retrieving a portion of a historical search session for a first search query, the portion including a first resource and a second resource, both the first and the second resource being relevant to the first search query; generating an association parameter for the second resource, the association parameter being based on a first historical parameter and a second historical parameter; and, responsive to the association parameter for the second resource being above a predetermined threshold, associating the second resource with one or more of the first resource and the included search terms, thereby generating an annotated search index for the included search terms.

    摘要： Methods, systems, and computer program products for providing statistical data relating to a plurality of input files from a data warehouse. A plurality of bins are associated with a plurality of hierarchically ordered index fields. Each index field is associated with a parameter of the input files and is configured to accept an index field value from a predefined value domain associated with the index field. A lookup table is defined that includes a plurality of hierarchically indexed data structures and data containers storing statistical data for each index within the data structures. For each data structure, a primary key and at least one secondary key are formed by concatenating one or more bins in compliance with a hierarchy of the hierarchically ordered index fields to form a sequence of bins, The lookup table includes only one primary key per data structure.

    摘要： A system includes first and second data stores, each store having a set of materialized views of the base data and the views comprise a multistore physical design; an execution layer coupled to the data stores; a query optimizer coupled to the execution layer; and a tuner coupled to the query optimizer and the execution layer, wherein the tuner determines a placement of the materialized views across the stores to improve workload performance upon considering each store's view storage budget and a transfer budget when moving views across the stores.
