  • Database insert with deferred materialization
    Patent number: 9396218
    Abstract: According to one embodiment of the present invention, a system inserts data into a database object. The system associates the database object with a parameter specifying materialization of data for the database object. The system inserts data into the database object and materializes the data in accordance with the parameter to provide access to the data from the database object, wherein the parameter specifies a portion of the data to be materialized upon insertion. Embodiments of the present invention further include a method and computer program product for inserting data into a database object in substantially the same manners described above.
    Type: Grant

  • Data decompression utilizing pre-expanded dictionaries during decompression
    Patent number: 8902087
    Abstract: According to one embodiment, a computer-implemented method of decompressing compressed data is described. A first decompression dictionary is analyzed, the first decompression dictionary including a plurality of chains each with uncompressed data portions distributed in a non-contiguous manner within the first decompression dictionary based on an addressing scheme, where the uncompressed data portions of each chain form a corresponding uncompressed version of compressed data. A second decompression dictionary is generated by combining the uncompressed data portions of each of the chains in the first decompression dictionary to form uncompressed versions of compressed data and instructions are inserted within the second decompression dictionary to decompress compressed data. The compressed data are decompressed by applying the compressed data to the second decompression dictionary.
