In an embodiment, an online analytical processing (OLAP) server stores a plurality of version records describing versions of a data item. A version record may describe any open transactions for a version of the data item. The version record may specify a commit timestamp for the data item at a database and a valid timestamp at least as great as the commit timestamp. The commit timestamp and the valid timestamp may specify a validity range. The version record may also specify an expiration timestamp, which along with the valid timestamp may specify an unresolved range. The OLAP server may also identify a valid version of the data item for a query timestamp that corresponds to a query for particular data in the data item and that falls within either the validity range or the unresolved range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Version control based on a dual-range validity model","description":"Techniques related to version control based on a dual-range validity model are disclosed.
