Welcome to my Database Development repository! This project is a comprehensive collection of my work in SQL and T-SQL. It demonstrates a strong foundation in database design, advanced querying, and server-side programmability using Microsoft SQL Server.
The repository is divided into two main modules to showcase different levels of database expertise:
1. SQL Mastery
Focuses on the fundamentals of data retrieval and analysis.
- DML & DDL: Designing tables and managing data efficiently.
- Joins & Subqueries: Connecting complex relational data models.
- Aggregations: Generating business reports using grouping and summary functions.
- Views: Creating data abstractions for cleaner access.
Focuses on database programming, automation, and security.
- Programmability: Stored Procedures, Scalar/Table Functions, and Triggers.
- Control Flow: Implementation of
IF...ELSE,Loops, andError Handling. - Data Integrity: Transaction management (
COMMIT,ROLLBACK) and ACID properties. - Security: Dynamic SQL implementation and SQL Injection prevention.
- Modern Techniques: CTEs (Common Table Expressions) and Window Functions.
- Database Engine: Microsoft SQL Server (T-SQL)
- Tooling: SQL Server Management Studio (SSMS)
- Concepts: Database Normalization, Performance Optimization, and Security Best Practices.
Each folder contains scripts that I developed while mastering SQL Server. The goal was to build a deep understanding of how to handle data at scale and ensure that the backend logic is robust, secure, and high-performing.
Feel free to navigate through the folders above to see specific implementations and detailed README files for each module.
