The Introduction to SQL course is designed to equip students with a solid foundation in Structured Query Language (SQL), a powerful tool for managing and manipulating relational databases. This comprehensive course covers the fundamental concepts of SQL, including basic queries, indexes, normalization, and other essential topics, to provide students with a strong understanding of database management.

Throughout this course, students will learn how to write SQL queries to retrieve, filter, and sort data from databases. They will gain hands-on experience in constructing SELECT statements, using various operators and functions to extract specific information from tables. Additionally, students will explore more advanced query techniques, such as joining tables, subqueries, and aggregating data with GROUP BY and HAVING clauses.

Indexing is a critical aspect of optimizing database performance, and this course delves into its importance and implementation. Students will understand how to create and manage indexes to enhance query speed and efficiency. They will explore different types of indexes, including B-tree and hash indexes, and learn how to analyze query plans to identify potential performance bottlenecks.

Normalization, a vital concept in database design, is thoroughly covered in this course. Students will grasp the principles of normalization and learn how to transform unnormalized data into well-structured relational databases. They will explore the normalization levels, from first to third normal form, and understand the benefits of maintaining a properly normalized database schema.

The course utilizes a combination of theoretical explanations, practical examples, and hands-on exercises to reinforce students’ learning. By working with real-world datasets and engaging in interactive SQL coding exercises, students will gain proficiency in crafting efficient queries, designing appropriate indexes, and creating normalized database schemas.

Upon completion of this course, students will have a solid understanding of SQL fundamentals, enabling them to effectively interact with relational databases. They will be equipped with the skills to construct complex queries, optimize query performance through indexing, and design well-structured databases through normalization techniques.

Prerequisites: None. This course is suitable for beginners with no prior knowledge of SQL or database management. Familiarity with basic concepts of databases and spreadsheets is helpful but not required.

Course Duration: 8 weeks (24 hours of instruction)
