In my projects like Easy Life Store and Pet Service, I have been involved in database integration using MySQL. For instance, in the Easy Life Store project, I worked on integrating MySQL to manage customer data and inventory. I designed the database schema to ensure efficient data retrieval and storage. I also implemented stored procedures to automate repetitive tasks and optimize query performance. Additionally, I used MySQL triggers to maintain data integrity and consistency across different tables. This experience helped me understand the importance of a well-structured database in supporting application functionality and improving overall system performance.
