Abstract

In an approach for processing data in a database management system, a processor performs a delete operation on a first data container, wherein the first data container includes one or more data records and wherein the delete operation logically deletes at least one data record of the one or more data records. A processor associates a time of the performed delete operation with the first data container. A processor performs a write operation on a first data record of the first data container. A processor associates a time of the performed write operation with the first data record of the first data container. Responsive to receiving a database query directed at the first data container, a processor grants access to the first data record of the first data container based on, at least, the time of the performed write operation being chronologically after the time of the performed delete operation.
