SQL Foundations

SQL Foundations: Master the Fundamentals of Structured Query Language SQL (Structured Query Language) is a widely-used programming language designed for managing and manipulating relational databases. It is a must-have skill for any data analyst, data scientist, or database administrator. The SQL Foundations course is designed to teach you the basics of SQL, from creating and querying tables to manipulating data and generating reports. The course starts with an introduction to databases and SQL, including an overview of different database management systems and their features. You'll learn about the different data types supported by SQL and how to create tables with the appropriate data types. You'll also learn about primary keys, foreign keys, and how to set up relationships between tables. Once you've learned the basics of SQL syntax, you'll dive into the core concepts of querying data using SELECT statements. You'll learn how to filter, sort, and group data, and how to use aggregate functions to summarize data. You'll also learn how to join tables together to combine data from multiple sources. As you progress through the course, you'll learn how to insert, update, and delete data in tables using SQL's data manipulation language (DML) commands. You'll also learn how to create views and indexes to speed up queries and improve performance. In the latter part of the course, you'll explore more advanced SQL topics such as subqueries, stored procedures, and transactions. You'll learn how to write complex queries using subqueries, how to create and execute stored procedures, and how to use transactions to ensure data consistency. By the end of the course, you'll have a solid understanding of SQL and how to use it to manage and manipulate data in relational databases. You'll be able to write basic and advanced queries, create and modify tables, and use SQL to generate reports and insights. Whether you're just starting out with SQL or looking to expand your skills, the SQL Foundations course is a great way to master the fundamentals of this powerful language.
