Claim:
1. A computer implemented method comprising: determining, using a server coupled to a data source, whether an object stored in the data source received an update; identifying, using the server, based on the determining, at least one identifier associated with a pre-computed result set, the pre-computed result set being computed based on the object; and computing, using the server, an updated pre-computed result set using the identifier by applying the received update to the pre-computed result set, the updated pre-computed result set being computed based on at least one delta change to at least one row in a base table, wherein the at least one row is associated with a count being indicative of a number of times the at least one row has received an update and a type of operation associated with the update and describing at least one derivation for the at least one row based on the base table, the computing triggers a computation of an update of at least another pre-computed result set, the at least another pre-computed result set being dependent on the base table in accordance with a pre-computed result set definition tree, wherein the pre-computed result set definition tree is modified for computing the update of the at least another pre-computed result set in accordance with the update of the at least another pre-computed result set; wherein the at least one of the determining, the identifying, and the computing is performed by at least one processor of at least one computing system.
