Abstract
The paper presents a short analysis of research related to the problem of the data warehouse (DW) evolution. The main contributions of the paper are: a) analysis of existing methods and approaches to the DW schema evolution, and b) characterization of the general research idea for the DW schema evolution problem. The general research idea includes a meta-Data Vault (DV) model that will integrate the DW with the master data management (MDM) system. We believe the following issues could be resolved: a) tracking the origin of data, b) tracking the history of changes, c) avoiding loss of data, d) faster and simpler migration and transformation of data, and e) trend projections. Also, due to long-term storage of historical data and tracking the origin of data, the DW could be used as a complete system of records and as the basis for the data governance (MDM integrated with the DW).
