SQL Curriculum – Learning Summary

By the end of this course, students will gain a comprehensive understanding of databases and SQL, including how to manage, query, and manipulate data effectively. They will learn:

• Fundamentals of Data and Databases: Understand the types of data (structured, semi-structured, unstructured), the need for databases over traditional file systems, and the purpose and types of Database Management Systems (DBMS), including RDBMS and NoSQL.

• Core DBMS Concepts: Learn key DBMS properties such as ACID compliance, security, backup mechanisms, and multi-user support, along with real-world applications of different DBMS types.

• SQL Basics: Gain foundational knowledge of SQL, including syntax, structure, and the ability to perform basic CRUD (Create, Read, Update, Delete) operations.

• Data Definition Language (DDL): Understand how to define and manage database structures using commands like CREATE, ALTER, DROP, and TRUNCATE, and apply various data types and constraints.

• Data Manipulation Language (DML): Learn to insert, update, and delete data in a controlled and safe manner using proper query structuring and best practices.

• Data Query Language (DQL): Master SELECT queries, apply filtering, sorting, grouping, and aggregation, and use logical operators and expressions for refined data retrieval.

• Joins and Subqueries: Learn to retrieve and relate data from multiple tables using different types of joins and subqueries, and understand when and how to use each effectively.

• Indexes and Optimization: Understand what indexes are, how they work, and when to use them to enhance query performance.

• Window Functions: Use advanced SQL window functions like ROW_NUMBER(), RANK(), and aggregation functions for analytical queries.

• Views: Learn how to create, update, and manage views for simplified data access and abstraction.

• Transactions: Understand the concept of transactions and ACID properties, and learn to use COMMIT, ROLLBACK, and SAVEPOINT for data consistency and integrity.

• Stored Procedures and Functions: Develop reusable and modular code using stored procedures and user-defined functions, and understand the differences and benefits of each.

• Triggers: Learn to automate actions in response to database events using triggers, and explore their use cases and limitations.

This curriculum prepares students for real-world database management, data analysis, and backend development tasks using SQL, making them proficient in both foundational and advanced database operations.
