LU03a - Concept of a RDB
A Relational Database (RDB) is a structured method for storing and organizing data. The core idea is to represent data as related tables.
Key components
- Tables: A collection of related data organized into rows (records) and columns (fields). Each row represents a unique entity, and columns contain specific attributes.
- Records: A single row in a table, representing a specific instance of data.
- Fields: A column in a table, defining the type of data stored in each row.
- Relationships: Connections between tables based on shared data. Common types include one-to-one, one-to-many, and many-to-many relationships.
