SQL (Structured Query Language) is a programming language designed for managing and manipulating relational databases. It provides a standardized way to interact with databases, allowing users to retrieve, insert, update, and delete data. SQL is used by developers, data analysts, and database administrators to handle data-related tasks efficiently.
In SQL programming, you write queries to retrieve specific data from a database using keywords like SELECT, FROM, WHERE, and JOIN. You can filter data based on conditions, sort it, and aggregate it using functions like COUNT, SUM, AVG, and GROUP BY. SQL also supports data manipulation operations, such as INSERT, UPDATE, and DELETE, enabling you to modify the content of a database.
SQL is versatile and widely supported across different database management systems like MySQL, Oracle, SQL Server, and PostgreSQL. It is used in various applications, from simple web-based forms to complex enterprise systems. Mastering SQL allows you to effectively work with databases, analyze data, and generate meaningful insights.
1. The fundamentals of DQL and its role in interacting with databases.
2. How to retrieve data from a database using SELECT statements.
3. Techniques to filter and sort data using WHERE and ORDER BY clauses.
4. Joining multiple tables to combine data from different sources.
5. Aggregating data using functions like COUNT, SUM, AVG, etc.
6. Grouping and summarizing data using GROUP BY and HAVING clauses.
7. Modifying data in a database using UPDATE and DELETE statements.
8. Creating and managing database objects like tables and views.
9. Understanding best practices for optimizing queries and improving performance.

Thank you for the material that was presented well and clearly. I got to know better how to use SQL for data science. Hopefully, by learning this, I can implement it in the future as a Data Analyst.
