https://github.com/Steema/TeeBI/blob/master/demos/experiments/bigdata/OneBillion/readme.md This demo shows TeeBI capabilities with big quantities of data, rows and cells. It first creates a default dummy database of One Billion cells (thousand millions). Data is saved to a disk file in your TEMP folder: "big_data.bi" (4.5GB) in aprox 4 seconds. Once data has been created it can be loaded again from disk in aprox 2.5 seconds. The "Query and Visualize" form uses this big data to do some visualizations. (Queries traversing so many millions of rows are not immediate, of course !) But you can run them in a normal laptop. // Sum the amount of Sales year by year, all rows: BIQuery1.Measures.Add(BigData['Sales']['Total'], TAggregate.Sum); BIQuery1.Dimensions.Add(BigData['Sales']['Date']).DatePart := TDateTimePart.Year; BIComposer1.Data := BIQuery1.Calculate;

The reason why FMX Linux is only available for Enterprise and Architect is, that those are the versions targeting Linux as a target platform. With a Professional version you can't compile code for Linux.

They are the same product. The original author passed away. Embarcadero had to renegotiate a new deal with his estate in order to continue providing the product. So any emails should be directed to Embarcadero. Embarcadero will continue developing and providing FMXLinux as an option, but only for Enterprise and Architect with Active subscription, AFAIK.
