If you can generate a file-based (JSON) model for each new version of a database, produced by a Flyway migration, then you have an easy way to run simple reports to help you search, list, and understand the structure of these databases. I'll show how to produce the models using PowerShell and then run some queries against them to generate the reports. Read more
Flyway provides a database-independent way for a team to track, manage and apply database changes, while maintaining strict control of database versions. It updates a database by running a series of versioned migration scripts, in order, and keeps track of all the changes in a special "schema history" table. It sounds simple, but it is easy to derail this team discipline if you don't find the right answers to the following questions… Read more
The payback of DevOps is not simply in automation but in using that automation to increase the visibility of the development processes. This article demonstrates way to make Flyway developments more visible, regardless of your RDBMS, such as by providing a detailed migration history, and change reports that reveal detail of what is going on to all involved.

The FlywayTeamwork PowerShell framework is designed to help get you started quickly with scripting Flyway migrations for a range of database systems. It introduces a PowerShell task library to help with the scripting of repetitive chores and to generate some of the 'build artifacts' that are often required during team development work. This article explains the basics of the framework's design and provides a demo how to use Flyway to migrate a PostgreSQL database, while generating a high-level narrative of the changes made between versions.

Before you get very far with database development and testing, you need to be clear about your strategy for handling data. In this article I'll explain some of these issues in general terms, and then demonstrate how you can navigate these problems easily with Flyway. Read more
Explaining some of the 'gotchas' that can trip up the unwary Flyway user, and how to avoid them. One or two of these you'll encounter quickly, such as the case-sensitivity of parameters and arguments. Others, such as potential problems with undo scripts or running scripted callbacks, only when you are tackling more complex development processes. Read more
We'll step through the process of using Flyway Teams to support database branching and merging, where the team split the development effort into isolated, task-based branches, and each branch has its own development database. Read more
Describing a route from a basic, 'managed' system of database development to use of branching and merging and CI, using Flyway. By taking these steps, you'll reduce development conflicts, lift testing restrictions, and the organization will have much more flexibility on the release of features and bugfixes. Read more
Database versioning brings more control to team-based database development and helps avoid many of the errors that often creep into database delivery. This article explains all the requirements of a semantic versioning system for databases, from specifying the format of the version numbers, to deciding where to store them and how to process and compare them. Read more
This article describes a route to adopting Flyway in order to bring management and control to a chaotic database development process. It is based on use of Flyway migrations to update a database from version to version, while maintaining object-level source scripts for tracking changes between versions. Read more
