The ER-Model (Entity-Relationship Model) helps connect the theoretical and conceptual data in the form of graphical representation. The ER-Model notes for GATE PDF include all the concepts, solved questions, and help prepare the GATE Exam. This topic is an important one in the Computer Science Engineering GATE Exam. The ER-Model is a vast topic that helps in establishing an association between different entities. It helps in connecting different entities and establishing a conceptual database or relation. The ER-Model topics for GATE CS fall under the umbrella category of Databases.

Important ER-Model Topics for GATE CS

While preparing for the Computer Engineering GATE Exam, ER-Model is an important topic under the database. There are concepts and attributes which fall under the ER-Model syllabus for GATE. It includes a complete explanation of the relational database.


The entities can be distinguished as real-world objects, and ER-Model helps establish a relationship amongst different entities. When similar entities are grouped, it is called an entity set. It is grouped as strong and weak entity sets. Each of them is different from one another.


The attributes are the property which describes the entity, or the entity set. Each of the attributes has a domain. There are signs and symbols which represent the attributes.
