A semantic data model (SDM) is a high-level semantics-based database description and structuring formalism (database model) for databases. This database model is designed to capture more of the meaning of an application environment than is possible with contemporary database models.
SDM was developed in 1970 by a company known as PANDATA, now part of Cap Gemini, which itself was created as a joint venture by three Dutch companies: AKZO, Nationale Nederlanden and Posterijen, Telegrafie en Telefonie (Nederland). The company was founded in order to develop the method and create training materials to propagate the method.
