SQL Server Integration Services provides a wide variety of features that helps developers to build a robust Extract, Transform and Load process. After many years contributing to SSIS related tags on Stackoverflow.com, I can say that many developers have some misunderstanding about SSIS features (SSIS OLE DB Source, SSIS Expressions, SQL Server destination …) especially those which are very similar and have some common usability.Read more »

Prediction, is it a new thing for you? You won’t believe you are predicting from the bed to the office and to back to the bed. Just imagine, you have a meeting at 9 AM at the office. If you are using public transport, you need to predict at what time you have to leave so that you can reach the office for the meeting on time. Time may vary by considering the time and the day of the week, and the traffic condition etc. Before you leave your home, you might predict whether it will rain today and you might want to take an umbrella or necessary clothes with you. If you are using your vehicle then the prediction time would be different. If so, you don’t need to worry about the rain but you need to consider the fuel level you need to have to reach to the office. By looking at this simple example, you will understand how critical it is to predict and you understand that all these predictions are done with your experience but not by any scientific method.Read more »
One shared characteristic among popular data visualization tools such as Power BI is the ease at which data can be extracted from a variety of disparate data sources, usually at a click of a button, as shown in Figure 1. Such convenience, though, tends to come at a cost as you often have little control over how background scripts used to extract data are generated. Yet, this should be of utmost concern for data architects and BI developers alike as rarely do you find auto-generated scripts that are efficient and optimal. In this article, join me as I put on my DBA hat and trace, monitor and review SQL batch statements that are auto-generated by the Get Data feature in Power BI using SQL Server Extended Events.Read more »
Just over a year ago, I published How to migrate SQL Server 2017 Master Data Services Models into another server article, that essentially demonstrated the migration of a SQL Server Master Data Services (MDS) model from one MDS instance to another. Like many of my previously published articles, I have since used the aforementioned article as a technical reference (i.e. syntax lookup for using MDSModelDeploy.exe utility) during the implementation of MDS-related projects for my clients.Read more »
Whilst Power BI continues to be the leading data visualisation tool in Gartner’s BI quadrant, Dynamics 365 for Customer Engagement (formerly Dynamics CRM) remains one of popular business platforms for driving sales and facilitating customer communications. Thus, an integration of Power BI into Dynamics 365 for Customer Engagement ensures that you get to explore your Dynamics 365 for Customer Engagement data via a powerful and rich data visualisation tool. However, as indicated in Figure 1, Dynamics 365 for Customer Engagement plans often come with a Power BI free license thereby limiting the type of Power BI features available to you. In this article, we look at how you can get the best out of your Power BI free license for the purposes of embedding Power BI artefacts into Dynamics 365 for Customer Engagement. Going forward, any references to Dynamics 365 for Customer Engagement plan in this article will be shortened to Dynamics 365.Read more »

SSAS interview questions is a new article for people looking for SSAS jobs.
In our previous article, we talked about SSIS interview questions. In this new article, we will talk about the SSAS interview questions to be prepared for an interview for a job using SQL Server Analysis Services.Read more »
These SSIS interview questions cover many of the top topics that you will be asked when applying for your next SSIS developer job. Each question has links to articles that cover the topic in depth.Read more »
I have seen many organizations receive data from various sources and import into SQL Server. You might receive data in various formats and want to import into SQL Server. We can prepare a ETL (Extract-Transform-Load) process to import data into the SQL Server. In doing so, might receive data in a compressed file, which helps to send data over the network using a ZIP file format because it reduces the file size significantly. If we are receiving a ZIP file to import into SQL Server, we need to unzip it and then only we can import data. We might need to create a ZIP file as well from the existing files.Read more »
Power BI Desktop is a useful reporting and analytical tool to represent data in various formats. These presentations help us to quickly understand information and circulate it to stakeholders in a visual fashion.
The SSRS report builder is a powerful tool for data visualization. In this article, we will take a first step into familiarizing ourselves with the SSRS report builder and we will also demonstrate a very basic SSRS report example. Additionally, we will review the self-service business intelligence approach just because this approach can be implemented through the SSRS report builder very easily.Read more »
In this article, we will show how to convert dates from dd/mm/yyyy to mm/dd/yyyy using the Script component and also derived columns in SSIS. We will also explain when to use a derived column (DC) and when to use the Script Component (SC).Read more »
Power BI Desktop amplifies the value of data. We can connect to multiple data sources and visualize the data interactively. One of the best parts of Power BI Desktop is the custom visual feature. It allows developers to create custom visuals and users can then download these visuals from the marketplace and use it as per the data set requirements. We can prepare reports using Power BI Desktop and share the reports using the Power BI service.Read more »
In this article, we will explore SQL Server Reporting Services (also known as SSRS) architecture and its main components. We will also discuss SSRS extensions and related tasks. Additionally, we will discuss the Report Server and Report Server temporary databases.Read more »
In this series of articles on SQL Server FILESTREAM (see TOC at bottom), we explored various ways to store unstructured data in the file system with the metadata in SQL Server tables. If we have a large number of objects in the file system, it is advisable to use the fast disk for storage purpose. It is faster and provides better IO in comparison with the traditional file system.
Power BI Desktop helps to visualize complex data with the help of inbuilt and custom visualizations. It allows integrating data from the various data sources and preparing visualization from it.
Microsoft recently integrated the Python programming language in the Power BI. Python is a powerful object-oriented language and is used by the data analyst and scientist to analyze complex datasets. We can now use the Python as a preview feature in the Power BI August 2018 release onwards. We can now use Python scripts to generate custom visualization. The combination of these technologies is akin to 1 + 1 = 3 or like the famous ad for Reese’s Peanut butter cups, when chocolate was introduced to Peanut Butter 😉Read more »
