Abstract: In at least some embodiments, a system includes a client layer having a client computer with a database query interface. The system also includes a database layer having a relational database and an object model database. The system also includes an application layer in communication with the client layer and the database layer. The application layer is configured to receive an object form query from the database query interface, translate the object form query to a structured query language (SQL) query, and forward the SQL query to the relational database. The object form query comprises an object, object property criteria, and object history criteria.
