Abstract

Described herein is a technology for facilitating delta data load. In some implementations, history tables corresponding to physical tables in a data source are provided in a database layer. The database layer includes change list tables corresponding to the history tables and a physical data model based on one or more physical tables. Delta data is determined by analyzing the change list table to create delta data summary tables. Key lists are generated for summary tables corresponding to physical tables which physical data is based. The delta data is applied to the physical data model.
