Abstract
A device may store information associated with a group of items in a database. The information associated with a particular item may include a group of versions of a particular attribute. A particular version of the particular attribute may include a value associated with the particular attribute and a timestamp. The device may receive a query that specifies a time; determine that the query is associated with the particular item; and determine, based on the specified time, which version of the particular attribute is associated with the query. The device may determine which version of the particular attribute is associated with the query by identifying, based on the timestamps associated with the versions of the particular attribute, a version of the particular attribute that is a newest version, of the versions of the particular attribute that are associated with timestamps that are before or concurrent with the specified time.
