The following practices are not required, but I have found them really useful, and you should at least consider using them in your new projects.We found that following format for the database version string is most flexible: The first element changes on major releases / phase of a system, e.g. The two subsequent elements are controlled by developers.Power Shell is Microsoft’s task automation framework consisting of a scripting language built on top of the . On the other hand, PSake is a domain-specific language written in Power Shell to create builds using a dependency pattern similar to Rake or MSBuild. Each Task is a function that can define dependencies on other Task functions.Our upgrade script is written as a single PSake task.You (as a developer) do not always compare it against the original.So it is hard to detect situations when different versions of the upgrade script have been applied to a database instance.
Moreover it speeds up the delivery process and makes it more resilient.
Furthermore, with automation the upgrade process could be easily plugged into the CI process.
At Objectivity we use the PSake module (Power Shell) to automate the process.
Revision is incremented when non-breaking changes are applied to the database (e.g. In theory, the upgrade scripts should be written in such a way that they can be run without modifications on any environment.
This means that they should not contain any paths, names of database instances, SQL user names or linked server configurations.
Data can be generally divided into two groups: It is recommended to keep these groups separated from the beginning of a project in order to avoid another “last mile” problem.
