DATAZEN licensing

Because I found some questions about the licensing of DATAZEN, I take this opportunity to clarify some points.

Currently the only totally free Microsoft tool for BI is the PowerBI (The basic version, with its limitations).

To use SQL Server Reporting Services is required a SQL Server license and to use Excel is required a Microsoft Office license... quite linear.

For DATAZEN, it can be said that this is a "free" software with 2 conditions for the final client:
- Must have the an Enterprise version of SQL Server (not just the standard version).
- Must have an active Microsoft Software Assurance.
So the "free" is relative ...

Everything becomes very clear when we want to download Datazen Enterprise Server for later installation (see following image).

I think it is clarified the DATAZEN licensing.
