Summary

With an understanding of what SQL injection is and why it is important to an organization, we can shift into a discussion of how to prevent it.

Performance Monitoring via SQL Server Query Store

SQL Server Query Store is a performance monitoring tool that helps us evaluate the performance of a SQL query in terms of several different performance metrics such as CPU and Memory Consumption, execution time and the I/O cycles consumed by the query. Query store is similar to the windows “Task Manager”. A task manager provides information about the CPU, Memory, Network and Disc consumption of a process. Similarly, the Query Store provides insight to similar information.
