Curriculum

Introduction

This introductory section lays the groundwork for your SQL and PostgreSQL journey. You'll begin with a course overview and tips for success, followed by an exploration of fundamental database concepts. The section culminates with hands-on installation guides for PostgreSQL on Windows and Mac operating systems, including a brief overview of the pgAdmin tool, essential for database management.

Quick Start with SQL: Part I

Dive into the core of SQL with this section. Learn the fundamentals of SQL syntax, database creation, and data manipulation using `CREATE TABLE`, `INSERT`, `SELECT`, `JOIN`, `GROUP BY`, `UPDATE`, and `DELETE` statements. You'll practice adding data from Excel via pgAdmin and reinforce your learning through quizzes focusing on creating, inserting, modifying, and deleting data, along with essential concepts like table joins.

Quick Start with SQL: Part II

Building on Part I, this section delves into crucial database concepts: primary and foreign keys, indexing, and transaction management. Through practical exercises and quizzes, you’ll master these elements, ensuring data integrity and efficient query performance.

Intermediate Assessment

Put your knowledge to the test with a comprehensive intermediate assessment, covering the concepts learned in the previous sections. This assessment helps identify areas for reinforcement and ensures a strong foundation before proceeding to more advanced topics.

Data Definition Language (DDL)

This section focuses on the Data Definition Language (DDL), covering the creation and deletion of tables, the implementation of constraints (default values, check constraints, NOT NULL, and UNIQUE), primary and foreign keys, and the modification of existing tables using `ALTER TABLE`. Reinforce your learning through a series of quizzes.

Data Manipulation Language (DML)

Here, you'll master the Data Manipulation Language (DML), learning to insert, update, and delete data efficiently. The section also covers the use of `RETURNING` for retrieving data from modified rows, with a quiz to solidify your understanding.

Data Query Language (DQL)

This in-depth section focuses on the Data Query Language (DQL), covering advanced techniques for data retrieval. You will learn to use `SELECT`, `FROM`, various types of `JOINs`, `WHERE` clauses, `GROUP BY` and `HAVING` for grouping and post-filtering, window functions, `UNION`, `INTERSECT`, `EXCEPT`, `ORDER BY`, `LIMIT` and `OFFSET`, `VALUES` lists, and Common Table Expressions (`WITH`). Numerous quizzes test your comprehension of these powerful techniques.

Data Types

Understand the various data types available in SQL and PostgreSQL. This section covers numeric, character, date/time, and Boolean types with quizzes to assess your understanding.

Functions and Operators

Master the use of functions and operators in SQL. This section covers logical, comparison, mathematical, string, and date/time functions and operators, all reinforced with practice quizzes.

Conclusion

This concluding section summarizes the key concepts learned throughout the course and provides guidance on your next steps in your SQL and PostgreSQL journey.
