A Data Model in software engineering is an abstract model that organizes and documents the business data for interaction between team members and is used as a plan for creating applications, how data are accessed and stored. According to Hoberman (2009), "A data model is a wayfinding tool for both IT professionals and business, which needs a set of text and symbols to precisely illustrate a subset of real information to enhance communication within the organization and thereby lead to a more stable and flexible application environment."

Generally data models are described in a data modeling language.
