Database optimization tips for Developers and SQL Server DBAs

Database Optimization for Developers:

  1. If your application stops working suddenly, it may not be a database issue. For example, maybe you have a network problem. Investigate a bit before you accuse a DBA!
  2. Even if you’re a ninja SQL data modeler, ask a DBA to help you with your relational diagram. They have a lot to share and offer.
  3. DBAs don’t like rapid changes. This is natural: they need to analyze the database as a whole and examine the impact of any changes from all angles. A simple change in a column can take a week to be implemented—but that’s because an error could materialize as huge losses for the company. Be patient!
  4. Do not ask SQL DBAs to make data changes in a production environment. If you want access to the production database, you have to be responsible for all your own changes.

Database Optimization for SQL Server DBAs:

  1. If you don’t like people asking you about the database, give them a real-time status panel. Developers are always suspicious of a database’s status, and such a panel could save everyone time and energy.
  2. Help developers in a test/quality assurance environment. Make it easy to simulate a production server with simple tests on real-world data. This will be a significant time-saver for others as well as yourself.
  3. Developers spend all day on systems with frequently-changed business logic. Try to understand this world being more flexible, and be able to break some rules in a critical moment.
  4. SQL databases evolve. The day will come when you have to migrate your data to a new version. Developers count on significant new functionality with each new version. Instead of refusing to accept their changes, plan ahead and be ready for the migration.
