Final SSIS package with Data Mining Query for Data Mining Query in SSIS.

Data Mining Query in SSIS

May 12, 2020 by

In this article, we will be discussing how SQL Server Integration Services (SSIS) can be used to predict data mining models built from SSAS. In this article, we will be looking at the Data Mining Query in SSIS. During the data mining article series, we have discussed all the Data mining techniques that are available in SQL Server. The discussed techniques were Naïve Bayes, Decision Trees, Time Series, Association Rules, Clustering, Linear Regression, Neural Network, Sequence Clustering. Further, we discussed how the accuracy of the data mining models can be verified.

Getting started with Azure CLI 2.0

May 12, 2020 by

In this article, we are going to understand what Azure CLI is and how to work with it. For the purpose of this article, we will take the version 2.0 to demonstrate the features and functionalities. The Azure CLI, as the name suggests is a cross- platform and open-source command-line tool that we can use to create or manage resources in the Azure Portal. This tool gives us the ability to issue commands right from the windows command prompt and deal with the Azure resources. Since this tool is a cross-platform, that means the users can easily install the utility on Windows, Linux or Mac OS and still work with the same set of commands without making any changes.

SQL Server PIVOT TABLE - the data model we'll use

Learn SQL: SQL Server Pivot Tables

May 11, 2020 by

In the previous few articles in this series, we’ve set the foundations on how to create a report. We’ll take one step further and see how to use the SQL Server PIVOT table operator. We’ll start from the simple query and slowly progress towards dynamic SQL and PIVOT. Let’s start.

Lever T-SQL to dynamically define duplicate SQL Server database table rows

May 11, 2020 by

Introduction

Lever T-SQL to handle duplicate rows in SQL Server database tables article highlighted T-SQL features that detect and handle duplicate SQL Server table rows. The techniques work well, but they rely on fixed duplicate row definitions. This article extends those techniques, showing how to define duplicate rows in a dynamic way.

Lock Configurations with SQL Bulk Insert

May 11, 2020 by

One challenge we may face when using SQL bulk insert is whether we want to allow access during the operation or prevent access and how we coordinate this with possible following transactions. We’ll look at working with a few configurations of this tool and how we may apply them in OLAP, OLPT, and mixed environments where we may want to use the tool’s flexibility for our data import needs.

Export Data Tier Applications in SQL Server Management Studio

An introduction to Data-Tier applications in SQL Server

April 29, 2020 by

In this article, I’m going to introduce the data-tier applications in SQL Server. As the official documentation from Microsoft says – “Data-tier applications in SQL Server are a logical entity that can be used to develop and manage most of the SQL Server objects like tables, views, stored procedures, functions etc. as a self-contained package“. Essentially, what that means is it is a component of SQL Server, using which we can develop, build, test and deploy databases for SQL Server just like we can do for any other web or desktop applications.

Measuring the Accuracy in Data Mining in SQL Server

April 29, 2020 by

In 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.

How to connect to a remote MySQL server using SSL on Ubuntu

April 28, 2020 by

In this article, the steps to connect to remote MySQL databases using Secure Sockets Layer (SSL) will be shown. MySQL is one of the most popular relational database management systems and by default, is configured to accept only connections from the machine where MySQL is installed. To connect to the MySQL database which sits on another machine, the additional configuration must be set to accept the remote connection with secure SSL encryption.
