发明名称 Method and system for sorting database tables according to a sort pattern and sort order
摘要 A database is created from a set of data by identifying the patterns in the data set, storing the patterns in a memory device, and generating a representation of the database structure using pointers to the stored patterns. The use of pointers to store the patterns can greatly reduce the amount of memory or other space required to store the data set by replacing duplicate patterns with additional pointers, which are normally considerably smaller in size. In addition, the use of pointers may allow for more rapid searching, sorting, and other operations on the database. The representation of the database may use pointers in a tree structure to identify nodes and reduce searching and other operations. A tree structure representation of a table may use a pointer to a pattern for the base leaf node (e.g., nodes that do not branch) while using pointer pairs to represent branching nodes.
