SQL-in-depth

Welcome to the SQL in Depth repository! In this project, we explore the fundamentals and advanced concepts of SQL using both MySQL and PostgreSQL databases. SQL (Structured Query Language) is a powerful tool for managing and manipulating relational databases, and this repository serves as a resource to document what we've learned along the way.

Introduction

SQL is a fundamental language for working with relational databases, and understanding its intricacies can greatly enhance your ability to work with data effectively. In this project, we delve into SQL concepts, best practices, and practical use cases using two popular relational database management systems: MySQL and PostgreSQL.

MySQL

MySQL is an open-source relational database management system known for its ease of use and performance. In the context of this project, we have explored the following aspects of MySQL:

  • Getting Started: Setting up MySQL, creating databases, and connecting to them.
  • Basic Queries: Writing simple SELECT, INSERT, UPDATE, and DELETE queries.
  • Advanced Queries: Delving into JOIN operations, subqueries, and aggregate functions.
  • Indexing and Optimization: Optimizing SQL queries through indexing and performance tuning.
  • Transactions: Understanding transaction management and the importance of ACID properties.

PostgreSQL

PostgreSQL, often referred to as Postgres, is another powerful open-source relational database management system. Here, we have covered various topics related to PostgreSQL:

  • Installation and Setup: Setting up PostgreSQL and connecting to databases.
  • Data Types: Exploring data types and their usage in PostgreSQL.
  • Advanced SQL Features: Working with advanced SQL features like window functions.
