  • Publication number: 20190303459
    Abstract: A search engine identifies external data records that describe similar entities and may each conform to a different data format or source schema. The engine derives mappings capable of translating data values between differently formatted attributes of two source schemas and uses these mappings to identify degrees of similarity between attributes and schemas. When the search engine receives a search request, the engine translates submitted search criteria into values of a first schema's attributes and then uses the mappings to map those values onto selected attributes of other schemas. The search engine then uses each schema's selected attributes to select external data records formatted in that schema. Each selected record is assigned a match score that is weighted by the similarity of the record schema's selected attributes to the search criteria. Records are then retrieved in order of decreasing match score.

  • Patent number: 10318512
    Abstract: The present disclosure relates to methods and systems for storing and querying data. According to the embodiments of the present invention, two-layer indexes are created for multi-dimension data, wherein the primary index is created based on two or more dimensions to retrieve respective data units of the data, while the secondary index is created based on specific dimensions to retrieve respective data blocks in the data unit. Correspondingly, when receiving a multi-dimension query request for data, the primary retrieval first determines a data unit including the target data based on a primary index, and then the secondary retrieval quickly locates a data block including the target data based on the secondary index. In this way, the multi-dimension retrieval can be efficiently performed. Moreover, by appropriately setting the size of a smallest data block, the I/O efficiency of data access will be significantly enhanced.
