In this section, we will outline the requirements for your final project. This project is designed to test your understanding of the concepts covered throughout the course and to give you practical experience in applying SQL to solve real-world problems.
Project Overview
Your final project will involve creating a database for a fictional company, writing SQL queries to manipulate and retrieve data, and optimizing the database for performance. You will be required to demonstrate your ability to:
- Design and create a database schema.
- Insert, update, and delete data.
- Write complex SQL queries to retrieve data.
- Optimize queries and database performance.
- Implement transactions and handle concurrency.
- Use advanced SQL features such as stored procedures, triggers, and views.
Project Requirements
- Database Design
- Schema Design: Design a database schema for a fictional company. The schema should include at least five tables with appropriate relationships (e.g., one-to-many, many-to-many).
- Normalization: Ensure that your database is normalized to at least the third normal form (3NF).
- Data Manipulation
- Data Insertion: Insert sample data into your tables. Ensure that you have enough data to demonstrate the functionality of your queries.
- Data Update: Write SQL statements to update existing data in your tables.
- Data Deletion: Write SQL statements to delete data from your tables.
- Data Retrieval
- Basic Queries: Write basic SQL queries to retrieve data from your tables using SELECT, WHERE, ORDER BY, and LIMIT clauses.
- Joins: Write queries that involve joining multiple tables using INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN.
- Advanced Filtering: Use advanced filtering techniques such as LIKE, IN, BETWEEN, and IS NULL.
- Aggregation: Write queries that use GROUP BY and HAVING clauses to aggregate data.
- Subqueries: Write subqueries and nested queries to retrieve data.
- Performance Optimization
- Indexes: Create and manage indexes to optimize query performance.
- Query Optimization: Analyze and optimize your queries for better performance.
- Transactions and Concurrency
- Transactions: Implement transactions to ensure data integrity.
- Concurrency: Handle concurrency issues using appropriate SQL techniques.
- Advanced SQL Features
- Stored Procedures: Create stored procedures to encapsulate complex SQL logic.
- Triggers: Implement triggers to automate actions based on specific events.
- Views: Create views to simplify complex queries and improve security.
- Common Table Expressions (CTEs): Use CTEs to write more readable and maintainable queries.
- Window Functions: Use window functions to perform calculations across a set of table rows.
Deliverables
- Database Schema: A detailed schema of your database, including tables, columns, data types, and relationships.
- SQL Scripts: SQL scripts for creating tables, inserting data, updating data, deleting data, and retrieving data.
- Optimization Report: A report detailing the optimization techniques you used and their impact on query performance.
- Transaction and Concurrency Handling: SQL scripts demonstrating the use of transactions and handling concurrency.
- Advanced SQL Features: SQL scripts for stored procedures, triggers, views, CTEs, and window functions.
- Documentation: A comprehensive documentation of your project, including explanations of your design choices, SQL queries, and optimization techniques.
Evaluation Criteria
Your project will be evaluated based on the following criteria:
- Correctness: The correctness of your SQL queries and database design.
- Complexity: The complexity and completeness of your database schema and SQL queries.
- Optimization: The effectiveness of your optimization techniques.
- Documentation: The clarity and completeness of your documentation.
- Advanced Features: The use of advanced SQL features such as stored procedures, triggers, views, CTEs, and window functions.
Tips for Success
- Plan Ahead: Spend time planning your database schema and queries before you start coding.
- Test Thoroughly: Test your SQL queries thoroughly to ensure they work as expected.
- Optimize Early: Start thinking about optimization early in the project to avoid performance issues later.
- Document Everything: Keep detailed documentation of your design choices, queries, and optimization techniques.
- Seek Feedback: Don't hesitate to seek feedback from peers or instructors if you encounter any issues.
By following these requirements and tips, you will be well-prepared to complete your final project successfully. Good luck!
