Read more »SQL Server Integration Services or SSIS is used as an ETL tool to extract-transform-load data from heterogeneous data sources to different databases. After extracting data from the different sources, most often there are a lot of transformations needed. One of the frequent transformations is SSIS Conditional Split.

Read more »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. We ultimately want systems where SQL injection is impossible or very difficult to pull off. We then want systems where exploiting bugs is slow, laborious, and likely to raise monitoring alarms within an organization when attempted. The trio of layered security, prevention, and alerting can provide an immense advantage against not only SQL injection, but other data security threats.
Read more »Many security vulnerabilities are discovered, patched, and go away forever. Some linger and continue to plague software development and will continue to do so for years to come. Setting aside social engineering and non-technical attacks, SQL injection remains one of the top security threats to our data, as well as one of the most misunderstood.

Read more »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.
