In my projects, I've approached database integration by first thoroughly understanding the requirements and then designing a schema that aligns with the application's needs. For instance, in one of my projects, I used MySQL to manage the database for an e-commerce platform. I started by defining the tables and relationships to ensure data normalization and integrity. I then wrote SQL queries to handle CRUD operations efficiently. Additionally, I implemented indexing on frequently queried columns to optimize performance. Throughout the project, I worked closely with the development team to integrate the database with the application, ensuring seamless data flow and consistency. This approach not only streamlined the data management process but also improved the overall application performance.
