New fear unlocked: Databases

So I've just heard that tools can require databases, which are not automatically installed with the tool?

i.e. we can have a lovely tool panel for subdomains centralised here, and when a server installs the tools and says 'Look, we now have a Single-cell or Proteomics Lab', the tools may exist but fail because their databases must be also manually installed?

Is this how this works? This is clearly a problem for us...
