In this paper a novel conceptual data warehouse (DW) data model, the Conceptual Data Vault (C-DV) Model is presented. The C-DV extends logical and physical Data Vault (DV) Models, to enable conceptual modeling of source data worthy of preserving in a DW staging area as a System of Records. The advantages of DV model, namely flexibility of evolving DW structure using only additions to the model, and high performance of prompt loading, are now extended with a model appropriate during conceptual data discovery and/or analysis phase. Specifically we provided formalization for the C-DV Model as a platform independent conceptual DW model using meta-modeling, as well as defined a patterns based mappings from source data (conceptual entity relationship) models into the C-DV model.
