Abstract: The present invention discloses a document-based data definition generator. The document-based data definition generator provides data definitions for a document-base data model created by an engineer. The data definition generator receives the document-based data model and scans it for tables located therein. Upon locating a table, the data definition generator initializes a schema definition. An entity is defined in accordance with the table title and each table heading and table row are subsequently interpreted. After each table row has been interpreted, attributes are added. At the end of each table, the data definitions are generated in accordance with the defined schema, entity, and attributes. The generated data definitions are embedded within an integrated engineering computer environment in an engineering database and engineering software applications.
