Requires Microsoft SQL Server Management Studio to run the numbered SQL scripts in sequence.
This project is a learning exercise built with Microsoft SQL Server that shows how to design and query a simple employee management database. It is meant to demonstrate SQL skills from beginner to intermediate level using a realistic business scenario, rather than being a finished application someone would run in production. The database is organized around four tables: Departments, Employees, Projects, and a table linking employees to the projects they work on. A set of numbered SQL scripts builds up the project step by step, starting with creating the database and tables, then inserting sample data, and finally working through a series of query examples covering common SQL techniques such as selecting and filtering records, sorting results, removing duplicates with DISTINCT, limiting rows with TOP, using string functions like CONCAT, UPPER, and TRIM, handling missing values with COALESCE and ISNULL, formatting output, and grouping and summarizing data with GROUP BY and HAVING. To run the project, you open Microsoft SQL Server Management Studio and execute the SQL scripts in order, starting with the script that creates the database, then the one that creates the tables, then the one that inserts sample data, followed by the remaining scripts in sequence. Screenshots of the project's output are included in a separate images folder for reference. The author describes this as a personal learning project covering topics like database creation, table design, data retrieval, filtering, sorting, aggregate functions, and writing business oriented SQL queries, built while studying to become a data engineer. The README does not state a license, and the project is intended purely for learning rather than for reuse in a real company system.
A step-by-step SQL learning project that builds an employee database in Microsoft SQL Server and walks through common query techniques.
