One MySQL database or many SQL Server databases At the moment I have an in-house Access database, data stored by our online survey provider, and data stored by our project management provider, both in databases. What I want is an in-house database where I have all data harmonized. Now I see two options for us (since we are money limited)


Set up a MySQL-DB with all data in one database or
Set up many SQL Server Express databases


I have worked with a SQL Server database but I have not the experience to decide what is better and why. So it would be great if someone could help me to decide that and tell me why.
If hosting externally is an option, you can get a MSSQL Database on Azure for as little as $5/MO.  http://azure.microsoft.com/en-us/pricing/details/sql-database/

The Basic tier has a 2GB limit, but you can get 250 GB for $15/MO.

Azure plans also come with: 


  built-in backup support, with the ability to point-in-time restore
  your data from any transaction up to 35 days. Additionally you can
  automatically replicate to another Azure region of your choice. This
  enables you to easily implement a disaster recovery policy designed
  for your business needs.


Might be worth checking out for just a few $$ per month.
