Nested and recursive lists are used by Ancelus to directly implement an entity-relationship diagram
The detailed description of the developed models has been submitted in  therefore further, we will provide their short description in the form of rules of the mapping binary entity-relationship diagram
elements into ontology elements.
The Software Area in the ConceptDraw Solution Park includes the Entity-Relationship Diagram
Solution, Data Flow Solution, Graphic User Interface Solution, IDEF0 Solution, and the new-and-improved Rapid UML Solution.
The constructs and rules of the entity-relationship diagram
(ERD), functional scheme (FS) and data dictionary (DD) are presented.
To provide timely diagnostic feedback, this work first extracts a learner's database concept, an Entity-relationship Diagram
(ERD) (Chen, 1976), into a two-dimensional matrix.
An Entity-Relationship diagram
, commonly referred to as an E-R diagram, shows the main things (or entities) that have a collection of related data elements (fields) we want to store and the relationships between these entities.
However, in contrast with the REA model, the Grundrechnung does not provide an Entity-Relationship diagram
based convention for expressing the relevant entities and their relationships.
For example, students learn how an entity-relationship diagram
relates to a dataflow diagram, and how a dataflow diagram can be mapped to a process flow chart.
For example, an entity-relationship diagram
represents a conceptual decomposition of a database.
Identifying requirements for data input validation may also be facilitated in a UML class diagram (or an entity-relationship diagram
