Abstract
Data from a database object are processed. Transaction information for a set of data of the database object is stored separate from the set of data in an allocated storage space, where the transaction information indicates visibility of the set of data to other transactions. A map structure is generated indicating storage of the set of data and the allocated storage space of the transaction information. The transaction information is altered in response to a transaction to the set of data to alter visibility of the set of data. Altering the transaction information is accomplished by providing updated transaction information within a new storage space in accordance with the transaction to the set of data and generating a descriptor for the transaction indicating an existing location of the set of data and the new storage space.
