A method for adaptively building and updating a column store database from a row store database using queries. The method includes establishing the row store database for storing data, wherein at least one row of the row store includes attributes. The method includes establishing the column store including data structured to satisfy received analytic queries, wherein the column store includes attribute vectors corresponding to attributes in the row store, wherein at least one of the attribute vectors includes data used to satisfy previously received analytic queries. The method includes receiving change transactions directed to the row store, wherein the change transactions are ordered. The method includes when a first referenced attribute referenced by an analytic query corresponds to an attribute vector in the column store, updating the attribute vector based on log information corresponding to change transactions directed to the referenced attribute to satisfy the analytic query.
