    摘要: A method for estimating a runtime of a query of a data repository may abstract, extract, or otherwise generate one or more parameters of the query. Thereafter, the abstracted parameters may be associated with one or more statistical query records. From these statistical query records, a query runtime may be estimated. Related apparatuses, computer program products, and computer systems are also described

    摘要: Systems and techniques for mapping data structures in a data processing environment to help ensure the accessibility of stored information. In one implementation, an article includes a machine-readable medium storing instructions. The instructions are operable to cause one or more machines to perform operations. The operations include receiving a first data storage schema in which a characteristic in a first dimension table is mapped by a first table and a second table and generating a second data storage schema. The first table maps the characteristic to a first object that include attributes to which time information is irrelevant to data processing activities and the second table maps the characteristic to a second object that include attributes to which time information is relevant to data processing activities. The second data storage schema includes a fact table including at least some facts drawn from the first data storage schema and a second dimension table that includes at least some characteristics drawn from at least one of the first object and the second object.

    摘要: In one embodiment, a computer-implemented method comprises receiving a query. A data store stores data as a plurality of data sets. Each data set comprises a plurality of fields and a plurality of data elements. Each field is associated with a portion of data elements. The query identifies selected data sets and selected properties of the selected data sets. For each selected property, the data elements of the selected data sets associated with each selected property are determined. A first rating of the determined data elements of the selected data sets is determined based on a type of combination of a pair of selected data sets. For the selected data set pairs, a second rating of the pair is determined based on the first ratings for the selected properties. A model of a combination of the selected data sets is generated based on the second rating.

    摘要: A computer-implemented method comprising receiving a user request. The method analyzes the data in a plurality of data sets to find inconsistent mappings. Data of data sets, such as columns formed by a join condition, are compared to determine matching or non-matching distinct characteristic values. A composite data set is generated based on the comparison. Another data set is compared with the composite data set, and the composite data set is enhanced. Each data set is compared in sequence, if the composite data set is not empty, until all data sets are analyzed. A result set is generated based on the matching or non-matching distinct characteristic values. The method may also determine if a join operates as a data filter. The operations that are used for analysis may include ‘count distinct’, ‘intersection’ and ‘Boolean operators’.
