Provide concrete examples and, if possible, quantify your achievements (e.g., improved query performance by 30%). This will demonstrate your expertise and the impact of your work.
Example: "I have over five years of experience working with MySQL and Oracle. In my previous role at XYZ Corp, I was responsible for designing and implementing a new database architecture that improved data retrieval times by 40%. I also managed regular backups and recovery processes, ensuring data integrity and security. Additionally, I optimized complex queries, which resulted in a 30% performance improvement. My experience with SQL Server includes setting up and maintaining high-availability environments and performing regular performance tuning."
