Abstract
A computer database management system has a table buffer for buffering as yet uncommitted modifications of records in an original shared database table and a look aside index for redirecting original table accesses to the modifications in the table buffer. Record modifications in the table buffer are indexed by a modified value index having a same key structure as a user-defined index on the original table. An indexing logic performs index functions on both the user-defined index and modified value index to provide integrated indexing of the original table records and table buffer modifications with the user-defined key order.
