ER Model Homework Help


Entity-relationship model (ER model) is an abstract representation of data. Programmers usually use it to visualize the scheme of database in a form of entities and relationships between them. Actually ER Diagrams are used to specify data storing the project system and document system entities, and connections between them including object identification which are important for the specific problem, and their attributes. First of all these techniques are used for designing relational databases.

The key definitions in ER modelling are:

  • entity;

  • attribute (a characteristic of an object);

  • relationship;

  • primary key (cannot allow null values, each table has at most 1 primary key);

  • foreign key (referential constraint).
