A system and method that facilitates and effectuates transaction time indexing with version compression. The system includes an indexing component that partitions a database page containing multiple temporally related versions of a record into a historical page and a current page based at least in part on a time or a key. The system includes a compression component that constructs backward deltas for compressing earlier (historical) versions of records that are stored on the page. Because there is always an uncompressed version for each record on each page, decompression can be done based solely on information stored on the record's page.
