1. A computer-implemented method comprising: causing an engine to receive a single-source universe database comprising a plurality of details; causing the engine to analyze the single-source universe database to create a XML configuration file identifying a detail to be changed; causing the engine to register a new multi-source connection with a repository; and causing the engine to reference the XML configuration file to create a multi-source universe database including the multi-source connection and a changed detail by re-generating a business layer including a new object definition compatible with the multi-source universe database, the business layer further comprising a file formed by adding a generated derived table query including a join updated with a new column name and a new table name, to a re-generated data foundation.
