Relocate "Sample Data"

[yoid2000]

Currently Metabase include a few "Sample Database" tables.

The basic idea is good (give the user something to play with even if they don't have any tables), but it doesn't match our structure, where everything is either in "Anonymized Data" or "Personal Data" (i.e. Direct Data).

So I think we should have some sample data, maybe even the same four tables that Metabase uses (which is nice in a way because they a JOIN-able). (On the other hand, maybe four tables is too much....maybe two at most.)

Then when Dashboards starts, the sample tables are already shown in the Dashboards "Imported Tables" table, with the appropriate Protected Entity configuration.

Likewise they appear in Metabase under the "Anonymized Data" and "Personal Data" databases.

is this one superseded by #119 and can be closed?

Good question.

The argument for keeping sample data is so that someone can play with the system even if they have no data of their own. (Essentially the same reason that Metabase puts the data there in the first place).

So rather than dopping sample data, we could build sample queries for it in exactly the same way we do it for user data.

These sample queries could be in the executable itself so there is no delay in creating them...

This seems potentially useful to me.

Not superseded, just simpler to do and higher priority.
After removing the Sample data source, we can add a couple of example tables to our Anonymized/Direct data sources.
