To draw an Entity-Relationship (ER) model for e-tutorials, start by identifying the key entities such as "User," "Tutorial," "Instructor," and "Category." Next, define the relationships between these entities, such as "User enrolls in Tutorial" and "Instructor creates Tutorial." Use rectangles to represent entities, diamonds for relationships, and ovals for attributes, ensuring to indicate cardinality (e.g., one-to-many) where applicable. Finally, review the model to ensure it accurately reflects the e-tutorial system's structure and relationships.

What is E-R data model?
The Entity-Relationship Model is often referred to as a semantic data model, because it more closely resembles real world scenarios than, e.g., the relational model. . In the ER model, we model the concept of "Instructors." In the relational model we deal with names and phone numbers. . In the ER model, there is a distinction between entities (objects) and relationships between such entities. In the relational model, both concepts are represented by relations.
Differentiate between the E-R model and Relational model?
The E-R model (Entity-Relationship model) is a visual representation of entities, attributes, and relationships in a database, while the relational model organizes data into tables with rows and columns. The E-R model focuses on the logical design of a database, while the relational model focuses on the physical implementation of data storage and retrieval. E-R model uses entities, attributes, and relationships to depict data structures, while the relational model uses tables, keys, and relationships to organize data.
What is er model in dbms?
In software engineering, an Entity - Relationship model(ER model for short) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams or ER diagrams.learn more www.ngprakasam.hpage.com
