This week there was a headline that said "Open Source Software Powers 96% of Modern Applications, New Study Finds" and if you stopped reading there, you might think, hey, it's not in the apps I work on. Or you might think that because you use OSS software, most of the world also does. Microsoft, Oracle, […]

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.

A software bug causes a lot of legal issues in the UK. It's something that upsets Steve, partially because the software wasn't well tested.

Most applications have large and complex databases at the back end, making it hard for developers to adequately test their work before it goes out. Having a fast, repeatable process to deliver data on demand is an essential part of an effective software development lifecycle, ultimately leading to improved customer satisfaction. In this article, we’ll explore the journey our own engineering team went on to leverage our own tool, Redgate Clone, to spin up short-lived database instances in containers for automated testing.

Automated testing is a way to ensure you can repeatedly examine your code as you make changes by running a series of tests. Since these are automated, you have the ability to execute all tests with one programmatic call rather than hoping a developer runs all tests. This also allows the effort of writing tests […]

Comments posted to this topic are about the item SQL Server Columnstore Index Fragmentation
Hi i was surprised to see the approach my coworkers used to sunset talend...
The columnstore index is absolutely different than the traditional rowstore b-tree index. Because of this, it doesn't suffer from the same kind of fragmentation across pages as the b-tree index. Yet, it does suffer from a type of fragmentation brought about by an excess of deleted rows in a rowgroup and a lack of compression of storage because more things are in the delta store. While b-tree indexes use dm_db_index_physical_stats to show fragmentation, which system tables or DMVs can be used in SQL Server (prior to SQL Server 2025) to determine columnstore fragmentation?
