Abstract: Described herein are systems and methods of transforming data models, for example, creating a data warehouse. A directives model may be loaded based upon a parsed directives file. An entity model may be loaded, and tables, attributes, and foreign keys of a data warehouse model may be created based upon the directives model and the entity model. Mappings may be created between tables, columns, and foreign keys of the data warehouse model and entities, attributes, and relationships, respectively, of the entity model. Code to define a data warehouse may be generated based upon the tables, attributes, and foreign keys of the data warehouse model. Code to transfer data from the source data source can be generated based upon the created mappings. A lineage report can be generated that provides information identifying a corresponding source for each table and column in the data warehouse.
