  • Method and system for analyzing ordered data using pattern matching in a relational database
    Patent number: 8219581
    Abstract: Several methods and a system for analyzing ordered data using pattern matching over an indefinitely long ordered sequence of rows in a relational database are disclosed. In one embodiment, a method of a server includes receiving an ordered data in a relational database. The method further includes matching a pattern specified in a query on ordered data in a relational database in a single pass in constant space for overlapping mode of results. The method also includes creating an output data in the single pass in constant space for overlapping mode of results based on the matching of the ordered data with the pattern in the relational database query.
