Abstract
In a Database Management System (DBMS), an index is used to organize the data such that the data can be efficiently retrieved to satisfy queries. The index may be organized in blocks which are stored in memory or on disk of a computer system. To satisfy a DBMS request, such as an update or query of data, multiple index blocks may need to be retrieved and processed. The claimed subject matter reduces the number of index blocks that needs to be retrieved and processed to satisfy the DBMS requests.
