It is certainly easy for me to get lost in the number of things referred to
as "cache" - but in this case there is no Nginx, just plain Tomcat, i.e.
nothing "in front of it"

I just didn't understand why the analytics tables did not get
deleted/updated until I manually had to get rid of them. But probably this
was caused by the setting which Jason referred to?

I assumed I could do the following:
1) Run "DELETE FROM DATAVALUES"
2) Clear the "Cache" that is referred to under dhis-web-maintenance-
dataadmin/showCache.action
3) Clear my own browser cache
4) Run Analytics

But it seems my algorithm missed the step of switching to "No cache" ?
