Spaccapietra Ed., North-Holland, Google ScholarCited by: In this context, although the Enhanced Entity-Relationship (EER) Model is the "de facto" standard modeling language for database conceptual design, to the best of our knowledge, there are only two. one of them is a ternary relationship Books-for conference on the entity-relationship approach, pp 62–78 and represents the hierarchical segmentation by the Entity-Relationship model. An entity–relationship model is the result of using a systematic process to describe and define a subject area of business data. The data is represented as components (entities) that are linked with each other by relationships that express the dependencies and requirements between them.

Entity Relationship modeling is a process used to help us understand and document the informational requirements of a system as a logical or conceptual data model. When the model is complete, we then create a physical model in some database management system (DBMS); typically a relational DBMS, or relational database management system (RDBMS). Expert system design entity relationship. Reviews There are no reviews for 'Expert system design entity relationship' yet. Entity-Relationship (ER) and Object-Oriented (OO) formalisms are often used to model environmental information of databases or computer programs. The majority of the environmental information is georeferenced. However, for 20 years, researchers have proposed different methods to adapt ER and OO to model spatial data. An Entity–relationship model (ER model) describes the structure of a database with the help of a diagram, which is known as Entity Relationship Diagram (ER Diagram).An ER model is a design or blueprint of a database that can later be implemented as a database. The main components of E-R model are: entity set and relationship set.
