New premium database conference

Given our vast knowledge and prior experience in organizing “SQLDay” and “DeveloperDays” conferences, including “.NET DeveloperDays”, “Mobile DeveloperDays” as well as “InfrastructureDays”, we have now created a new conference dedicated to SQL Platform.

The SQL Platform conference is specifically designed for:

  • programmers and database administrators
  • software engineers
  • architects and designers of database systems

During the conference there will be one track about database administration and programming (DEV/DBA).

We also invite you to participate in day-long workshops in which you can test your knowledge and skills acquired during the conference (due to the character of the event the number of participants is limited!).

Among the lecturers on the day there will be notable experts in SQL technology and database area.

For more details, please go to our website and follow Facebook page.

Post-Conf sessions

Post-Conf will take place after the conference.

Kalen Delaney – SQL Server Query Plans — Reuse or Recompile

What determines when a plan is reused? When is it better to recompile? Reusing an inappropriate plan cause a huge reduction in query response time. On the other hand, recompiling a frequently run query every time it’s executed can also cause big performance problems.

Allan Hirt – The ABCs of SQL Server Availability

Your applications and end users need SQL Server instances and databases that both perform well and are online when they need to be. Additionally, the solution must be manageable and cost-effective. No big deal, right? Wrong.

Chris Adkin – Advanced Techniques For Super Scaling SQL Server

You are a DBA or developer working on applications with mission critical performance requirements so exacting that a level 400~500 understanding of the database engine is required in order to extract every last ounce of performance from the database engine.

Maciej Pilecki – Understanding the Query Optimizer

Did you ever wonder what the heck was the Query Optimizer thinking, coming up with this idiotic execution plan? During this full-day workshop, we are going to dive into the inner workings of the Query Optimizer to uncover some of the logic that drives it, decisions it makes based on the limited information available to it, and answer some of those questions in the process.
