Another significant patent is "Dictionary-based order-preserving string compression for main memory column stores." This patent describes methods and systems that utilize dictionaries for compressing a large set of variable-length string values with fixed-length integer keys in column stores. The dictionary supports updates, such as inserting new string values, without altering the codes for existing values. Additionally, a shared-leaves approach is introduced for indexing the dictionary, which compresses the dictionary itself while providing access paths for encoding and decoding.
