How to continuously delivery SQL-based app?

Question

I\'m looking to apply continuous delivery concepts to web app we are building, and wondering if there any solution to protecting the database from accidental erroneous commi

Answer 1

One of the strategies that is commonly adopted is to log the incremental sql statements rather than a collective schema generation so you can control the change at a much granular levels:

ex: 
change 1:
UP:
Add column
DOWN:
Remove column

change 2:
UP:
Add trigger
DOWN:
Remove trigger

Once the changes are incrementally captured like this, you can have a simple but efficient script to upgrade (UP) from any version to any version without having to worry about the changes that happening. When the change # are linked to build, it becomes even more effective. When you deploy a build the database is also automatically upgraded(UP) or downgraded(DOWN) to that specific build.

We have an pipeline app which does that at CloudMunch.
