Can you explain the limitations of the Limited version of the SQL Bridge module? According to this chart [inductiveautomation.com/pricing/comparison](http://www.inductiveautomation.com/pricing/comparison) the Limited version does not do Transaction Groups but according to your help manual “Transaction Groups are the heart of the SQL Bridge module”

Yes, transaction groups are the heart of the SQL Bridge Module. The Limited version of the SQL Bridge module gives you the Historical Group only. The full version of the SQL Bridge modules gives you all of the groups and the SQLTags historian.
