2.3. Converting ERD to a relational model — A Practical Introduction to …
https://runestone.academy/ns/books/published/practical_db/PART2_DATA_MODELING/03-ERD-to-relational/ERD-to-relational.html
A relational model organizes data into tables (relations) with rows (tuples) and columns (attributes). It is foundational for relational databases like MySQL, PostgreSQL, and Oracle. Below are the steps to create a relational model.
1. Identify Entities and Attributes
Entities represent real-world objects or concepts (e.g., Student, Course).
Attributes define properties of entities (e.g., Student has Name, Roll_No, Age).
2. Define Relationships
Establish relationships between entities: One-to-One: Each entity in A relates to one in B. One-to-Many: One entity in A relates to multiple in B. Many-to-Many: Multiple entities in A relate to multiple in B.
For example, a Student can enroll in multiple Courses, and each Course can have multiple Students.
3. Create Tables
Convert each entity into a table.
Attributes become columns.
Assign a Primary Key to uniquely identify each row.
Example for a Student table:
CREATE TABLE Student (
Roll_No INT PRIMARY KEY,
Name VARCHAR(50),
Age INT
);
