Chapter 9 - Structured Query Language

Do you want to learn more about the most popular and widely used query language in computer science? Do you want to understand how SQL works and how it is used to communicate with databases and perform various operations on data? Do you want to practice and implement SQL using Python as a programming language?

If you answered yes to any of these questions, then you will find this chapter very useful. In this chapter, you will learn about the concept and implementation of SQL. SQL is a standard query language that is used to create, retrieve, update, and delete data from databases. SQL is a universal and versatile language that can be used with various types of databases and applications.

Some of the topics you will cover in this chapter are:

• The definition and features of SQL: How SQL is defined and characterized by its syntax, keywords, commands, clauses, etc. 📝👩‍🏫👨‍🎓
• The data definition language (DDL): How DDL is used to create, alter, and drop database objects such as tables, views, indexes, etc. 📊📈📉
• The data manipulation language (DML): How DML is used to insert, update, delete, and select data from tables. 💻🖱️👍
• The data control language (DCL): How DCL is used to grant and revoke permissions and privileges to users and roles. 💬🔎👏
• The transaction control language (TCL): How TCL is used to commit, rollback, and savepoint transactions. 💰💵🔙
• The Python code for SQL: How SQL is coded and executed using Python as a programming language. 💻🐍👍

By studying this chapter, you will gain a deeper understanding of how SQL is essential and powerful language  for interacting with databases and manipulating data. You will also develop critical thinking skills to solve various problems and cases using SQL. You will also appreciate the importance of Python as a simple and powerful language  for implementing SQL.
