2. Entity–relationship model - Wikipedia

   en.wikipedia.org/wiki/Entity–relationship_model

   Diagrams created to represent attributes as well as entities and relationships may be called entity-attribute-relationship diagrams, rather than entity–relationship models. An ER model is typically implemented as a database. In a simple relational database implementation, each row of a table represents one instance of an entity type, and each ...

3. Database design - Wikipedia

   en.wikipedia.org/wiki/Database_design

   A sample entity–relationship diagram. One of the most common types of conceptual schemas is the ER (entity–relationship model) diagrams. Attributes in ER diagrams are usually modeled as an oval with the name of the attribute, linked to the entity or relationship that contains the attribute.

4. C4 model - Wikipedia

   en.wikipedia.org/wiki/C4_model

   Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML) , Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE) .

5. Data modeling - Wikipedia

   en.wikipedia.org/wiki/Data_modeling

   An entity–relationship model (ERM) is an abstract conceptual representation of structured data. Entity–relationship modeling is a relational schema database modeling method, used in software engineering to produce a type of conceptual data model (or semantic data model ) of a system, often a relational database , and its requirements in a ...

6. Conceptual model - Wikipedia

   en.wikipedia.org/wiki/Conceptual_model

   Entity–relationship modeling (ERM) is a conceptual modeling technique used primarily for software system representation. Entity-relationship diagrams, which are a product of executing the ERM technique, are normally used to represent database models and information systems. The main components of the diagram are the entities and relationships.

7. Associative entity - Wikipedia

   en.wikipedia.org/wiki/Associative_entity

   An associative entity is a term used in relational and entity–relationship theory. A relational database requires the implementation of a base relation (or base table) to resolve many-to-many relationships. A base relation representing this kind of entity is called, informally, an associative table. An associative entity (using Chen notation)

9. Enhanced entity–relationship model - Wikipedia

   en.wikipedia.org/wiki/Enhanced_entity...

   The enhanced entity–relationship (EER) model (or extended entity–relationship model) in computer science is a high-level or conceptual data model incorporating extensions to the original entity–relationship (ER) model, used in the design of databases.
