Power BI Desktop is the free tool from Microsoft for developing in Power BI. In this article, Robert Sheldon walks you through importing and manipulating data with the Query Editor in Power BI Desktop.
In this tip we look at how we can use Python and SQL Server 2017 to send alerts from SQL Server to Slack messaging service.
This week Steve Jones is wondering what the common mistakes that T-SQL developers make are.
How to create an automatic SQL restart or failover notification.
Stuffing table variables with hard-coded values to demonstrate concurrency.
In-Memory OLTP is a high performance, memory-optimized engine integrated into SQL Server 2014 and designed for modern hardware trends. In-Memory OLTP allows users to move data into memory resident tables while keeping other data in traditional, disk-based table structures. For performance critical workloads, users can also migrate Transact-SQL code to natively compiled stored procedures. This can provide additional performance gains. This paper aims to help readers understand some of the common architectural patterns where In-Memory OLTP has provided significant benefits. The paper also discusses considerations for migrating applications to In-Memory OLTP.

In-Memory OLTP (project “Hekaton”) is a new database engine component, fully integrated into SQL Server. It is optimized for OLTP workloads accessing memory resident data. In-Memory OLTP allows OLTP workloads to achieve significant improvements in performance, and reduction in processing time. Tables can be declared as ‘memory optimized’ to enable In-Memory OLTP’s capabilities. Memory-optimized tables are fully transactional and can be accessed using Transact-SQL. Transact-SQL stored procedures can be compiled to machine code for further performance improvements on memory-optimized tables. The engine is designed for high concurrency and blocking is minimal.
