Abstract

System, method and program product for estimating a cost of reconciling heterogeneous data sources. A transition cost for integrating together a first program to identify semantic conflicts, a second program to classify semantic conflicts and a third program to reconcile semantic conflicts is estimated. A steady state cost for managing and maintaining the integrated first, second and third programs is estimated. Another system, method and program product for estimating a cost of integrating heterogeneous data sources. A steady state cost of managing and maintaining a first program which identifies semantic conflicts between a cross data source query and schema elements in a data source is estimated. A steady state cost of managing and maintaining a second program which classifies semantic conflicts between the cross data source query and schema elements in the data source is estimated. A steady state cost of managing and maintaining a third program which reconciles semantic conflicts between the cross data source query and schema elements in the data source is estimated.
