== Tools for creating a data model for an application ==

While simple data models consisting of few tables or objects can be created "manually", large applications need a more systematic approach. The [[entity-relationship model]] method is used to establish a ___domain-specific data model. Other methods like the [[functional data model]] and [[object role modeling]] (ORM) also describe subsets/aspects of a data model and the application based on it. The [[Unified Modeling Language]] (UML) is another method more related to object-oriented data models. Especially the "Object Model" part has a number of parallel representations with the Entity-Relationship Model, but notably lacks the ability to support conceptual, logical, and phyiscalphysical traceability.
