Creating database - SS3 ICT Lesson Note
A database is a structured collection of data that allows you to store, manage, and retrieve information efficiently.
Creating a Database:
- Choose a Database Management System (DBMS): The first step is to select a DBMS, like MySQL, PostgreSQL, Oracle, or SQLite. This software will help you create and manage databases.
- Define the Database Schema: A schema is like a blueprint that outlines the structure of your database. It includes tables, their columns, data types, and relationships between tables. Designing a good schema is crucial for data integrity.
- Create Tables: Once the schema is defined, you create tables within the database. Each table represents a specific entity or concept, such as "Customers" or "Products." Define the columns for each table, specifying their data types and constraints.
- Insert Data: After tables are created, you can start inserting data into them using SQL (Structured Query Language) commands like INSERT INTO.
