DBMS and SQL Tutorial

DBMS and SQL Tutorial

This handbook is designed to give you a structured pathway through the world of databases and SQL. You’ll begin with key DBMS concepts like relational models, normalization, indexing, and transactions. Then you’ll delve into SQL – learning how to write queries for creating, reading, updating, and deleting data, how to join tables, how to optimise queries, and enforce integrity.

Why this handbook matters

Databases run almost every business application. If you don’t understand how data is stored, retrieved, structured, and secured, you’ll struggle when building systems, analysing data, or maintaining performance. This handbook fills that gap, giving you both the theoretical base and practical hands-on experience to work with data-driven systems confidently and efficiently.

Who this is for

- Developers, data engineers or analysts who want to deepen their understanding of how data is managed behind the scenes. - Students or self-learners preparing for jobs that involve database design, SQL querying or data handling. - Anyone working with relational data who wants to write better queries, optimise performance and design maintainable systems. - Professionals transitioning into roles involving database administration, data warehousing or backend development.

Prerequisites

This course is suitable for:

• Basic understanding of programming logic (variables, loops, conditionals).
• Familiarity with basic data types, arrays or lists.
• Comfort with using a computer and running queries or scripts.
• A willingness to work hands-on with tables, practice writing SQL queries and explore how data is structured.
