"EXPRESS is a standard data modeling language for product data. EXPRESS is formalized in the ISO Standard for the Exchange of Product model STEP (ISO 10303), and standardized as ISO 10303-11. This graphical notation supports a subset of the EXPRESS language. One of the advantages of using EXPRESS-G over EXPRESS is that the structure of a data model can be presented in a more understandable manner. EXPRESS-G is a standard graphical notation for information models."
[EXPRESS (data modeling language). Wikipedia]

The vector stencils library from the solution Information Model Diagrams contains specific data type symbols of the EXPRESS-G notation such as entity data type symbols, simple data type symbols, enumeration data type symbols, defined data type symbols, select data type symbols and specific attribute symbols for ConceptDraw PRO diagramming and vector drawing software. The Information Model Diagrams solution is contained in the Software Development area of ConceptDraw Solution Park.

Use the Information Model Diagrams solution to draw data model diagrams for your business documents, presentations and websites.

Example 1. Express-G Diagram - Family Scheme

The example above shows an EXPRESS data model for a family scheme.
"It contains a supertype entity Person with the two subtypes Male and Female. Since Person is declared to be ABSTRACT only occurrences of either (ONEOF) the subtype Male or Female can exist. Every occurrence of a person has a mandatory name attribute and optionally attributes mother and father. There is a fixed style of reading for attributes of some entity type:
-a Female can play the role of mother for a Person;
-a Male can play the role of father for a Person."
