Abstract
A database management system stores data for a table using a ledger which comprises journal and summary portions. A query processor of the database identifies a first set of operations to update a document of a table in accordance with an update command. The query processor identifies a second set of operations to update tables or views that are potentially affected by the update to the document. The query processor then causes the first and second sets of operations to be executed as an atomic unit.
