WHAT'S ABOUT EVENT / database conference

JOIN! 2018 is the third edition of our conference dedicated to the SQL Server Data Platform.

Last year we hosted over one hundred participants.
This year we would like to host notable and well-known experts in the SQL Server area. At the moment, we’re doing our best to tweak conference agenda.

This conference is specifically designed for:
– database administrators and developers
– software engineers
– architects and designers of database systems
– Business Intelligence developers
– data analysts

During the main conference, there will be 3 parallel tracks, covering Database Administration, Database Development and Business Intelligence.

In addition to the normal conference sessions, we would like to invite you to take part in full-day, pre-conference training sessions delivered by the best experts in the industry. You can save by registering to both the main conference and one of the pre-cons at the same time!

Warsaw is very well connected, both within Poland as well as internationally.

After registration and payment, please contact us for your visa invitation letter. We will need your full name, date of birth, nationality and passport number. In the unlikely case that your visa application is refused, we will refund your conference fee in full (requires a consulate statement denying visa).
Since the place of service delivery is in Poland, we have to charge VAT on top of the net amount and the "reverse charge" scheme does not apply in this case (it's different from export of services or goods to another EU country). You can, however, reclaim the paid VAT from Polish tax authorities under EU VAT return scheme. More on that here:
