Planning a Database Testing Strategy for Flyway

With Flyway, you can adopt a test-driven development strategy that will allow you to test and evaluate databases, and database objects, at every phase of the database development lifecycle. The further down the delivery pipeline that bugs appear, the more costly in time and resources they are to fix. This approach will allow you to catch many of them before the database change even gets committed to version control, making a continuous delivery process much easier to adopt and sustain. Read more

Without adequate answers, tasks such as multi-database management, automation and workflow, and Continuous Integration will be difficult. Hopefully, this article will help. Read more

Database Monitoring for Developers

Database monitoring is an essential part of database development and testing because it will reveal problems early and allow you to drill down to the root cause, as well as look for any worrying trends in behavior of the database, when under load. If you are delaying doing this until a database is in production, you're doing it wrong. Read more
