NextReports 8.0 version will bring something new in the way server can interact with data.
ETL (Extract Transform Load) process can be defined when any report is run or scheduled. ETL is practically selected in run formats list. After run, all data is brought locally to NextReports Server machine inside a OrientDB NOSQL database.
Saved data can be used by a new Analysis feature, which allows any user with necessary rights to play with data.
