 # Databases
 
 There are two databases for SBND: **development database** and **production database**. The "development database" is an intermediate stage used to validate the values that will later on be uploaded to the "production database", which is the one accessed by analyser modules and simulations. That means that, every time the database needs to be updated (whether it is a value changing, or including/removing variables) it will be implemented in the "development database" first. The change should be validated by the person requesting the change, and once confirmed that everything looks ok, the changes will be pushed to the "production database".
