Database Model Diagram

Since the most of applications keep their data in databases, the database design and database modeling play highly important role during the process of applications development, at this the time of recording and retrieving data from the database has a great value. In addition, software developers and database designers are well aware that only properly and accurately built data models allow to construct effective databases permitting to retrieve and write data quickly, that ultimately contributes to significant increase of applications performance, as well as ensures the scalability and flexibility of development. Therefore, during the process of applications development, it is recommended to pay special attention and sufficient amount of time to the database modeling and drawing the database model diagram.

EXPRESS-G Database model diagram

A database model is a type of data model, which is intended for determining the logical structure of a database, for setting relationships and constraints that define the ways of storing, organizing, accessing and also manipulating the data within a given database. The database models are built according to the established rules and concepts of their construction, and typically with help of data modeling notations defined by standard data modeling languages, such as EXPRESS and EXPRESS-G.

EXPRESS data modeling language is an information modeling language described in ISO 10303-11. It is an object-oriented, independent and neutral, and used to represent industrial product models at different stages of their life cycle. EXPRESS language is strictly formalized, so the information displayed by means of it can be interpreted in uniquely possible way. Designing EXPRESS-G diagrams with help of tools of ConceptDraw DIAGRAM software and EXPRESS-G data Modeling Diagram solution, using EXPRESS-G notation requires a minimum of time and efforts, while result will please with its professional look.EXPRESS Data Modeling Language *
