An introduction to Data-Tier applications in SQL Server
April 29, 2020In this article, I’m going to introduce the data-tier applications in SQL Server.

Measuring the Accuracy in Data Mining in SQL Server
April 29, 2020In this article, we will be discussing measuring Accuracy in Data Mining in SQL Server. We have discussed all the Data mining techniques that are available in SQL Server in a series of articles. The discussed techniques were Naïve Bayes, Decision Trees, Time Series, Association Rules, Clustering, Linear Regression, Neural Network, Sequence Clustering. Data mining is a predicting technique using the existing pattern. It is obvious that we won’t be able to predict 100% accurately. However, since we are using data mining outcomes for better business decisions, the result should have better accuracy. If the accuracy is very low, we tend not to use those data mining models. Therefore, it is essential to find out how accurate your data mining models are.

Importance of SQL Server Max Degree of Parallelism
April 21, 2020In this article, we will discuss how the Max Degree of Parallelism works in SQL Server and how does it improve the query performance. SQL Server Degree of Parallelism is the processor conveyance parameter for a SQL Server operation, and it chooses the maximum number of execution distribution with the parallel use of different logical CPUs for the SQL Server request. Microsoft SQL Server allows setting this Degree of Parallelism parameter value at the SQL Server instance level or Query level. If you do not specify the SQL Server Degree of Parallelism value at the SQL Server instance, then each request or operation has to rely on SQL Server default value and random CPU allocations.
