You have a couple options:
- If your data lives in files, you should put them in your project folder. Domino will track and revision all files in your project folder, even large ones.
- If your data is in an external database, you can connect to it as you normally would. Domino doesn't limit what kind of code you run, so it's fine to connect to external resources.
If your database resides behind a firewall, there are two ways to handle this:
- We can give you IP ranges for the Domino machines, so you can allow access to them through your firewall.
- Alternatively, we have a facility for securely associating a VPN configuration with your project, so your code will be connected to your VPN when it runs.
Let us know if you need help with either of these options. Our support team is happy to help you get set up.
