Better Database Incident Management with Redgate Monitor

This article demonstrates how Redgate Monitor helps teams manage database incidents efficiently, by providing the right data to the right people, at each stage of a tiered incident response system. With fewer distractions from routine issues, specialist staff can focus on core tasks while teams resolve problems faster and prevent future disruptions. Read more

Deterministic Data Masking in Redgate Test Data Manager

Redgate Test Data Manager is designed to provide secure, anonymized, and representative copies of production databases. This article focuses on the role of deterministic data masking, transforming PII consistently across tables, even when no logical relationship exists between them, and explains how it works.

Installing and Upgrading the Flyway CLI

This article demonstrates three ways to install and maintain the Flyway CLI. I start with the easiest way, which is to run it from Docker. Next, is a standard, manual installation on both Windows and Linux, complete with a PowerShell routine that uses aliases to make it easier to keep Flyway up to date and to switch between versions. Finally, I'll describe briefly the advantages and disadvantages of using a Package Manager like Chocolatey. Read more

The Importance of Access Checks and Controls in Database Development

This article illustrates the importance in any database development project of a 'multi-layered' approach to database access controls and security checks, based on the Principle of Least Privilege. It describes a security incident that was raised when databases related to a local development project were found to have been erroneously deployed to a remote test server. It explains the nature of the incident, what went wrong that allowed it to happen, and the measures that were put in place to prevent its recurrence. Read more

Forks in Flyway Database Development Work

Database forking allows teams to multi-task, working on different strands of development in parallel. It also allows them to manage several 'variants' of a production database, such as for SaaS applications with client-specific schema requirements. This article explains how Flyway supports and simplifies database forking, via use of Flyway's locations, baseline migrations and by mapping Flyway projects to schemas. Read more

Instant Database Reset and Easier Bug Fixing using Clones

The article demonstrates how the use of lightweight, containerized clones removes the problem of 'mopping up' after a database migration fails part way through, particularly in database systems like MySQL that don't support DDL transaction rollback. A quick reset to the previous saved revision provides 'instant rollback'. It also demos how they make it much easier and less disruptive to do retrospective bug fixing on older migrations. Read more

Using Flyway and Data Containers for Database Testing: Rapid Setup and Teardown

This article demonstrates how to use the rgclone CLI in Redgate Test Data Manager to automatically save each new version of a database created by Flyway as a data container revision, tracking which Flyway version maps to which container revision. We can then, from a single data container, load any version of the database during test setup, as well as quickly 'reset' a container during test teardown. Read more

Flyway’s Repair Command Explained Simply

The Repair command allows Flyway migrations to recommence on a database, following one or more validation errors. It modifies various details recorded in the schema history table, for applied migrations, to make them consistent with the data and metadata of the current set of Flyway migration files. This article explains what problems Repair can fix and how to run it safely, and a few alternative strategies. Read more

Data Container Revisions, Resets and Graduations

Redgate Test Data Manager allows developers to save each new version of a database as a data container revision. After making local development changes to the container, or running tests, they can instantly reset it to its starting revision. They can also load any previous revision and can even 'graduate' a revision to an image, providing a new baseline for ongoing team development. These techniques are especially effective when used in conjunction with Flyway, which automatically tracks the version of every copy of the database. Read more
