Available options for generating heatmaps in an SSRS report

September 17, 2018 by

As developers of business intelligence solutions, we tend to service different types of business users. Whilst a call center supervisor is more likely to consume reports that offer detailed breakdown of day-to-day performance of her call center agents, senior managers on the other hand often prefer big-picture analytical reports that represent data in a form of colorful graphs and charts. Not surprisingly, such reports often make use of heatmap controls to provide visually effective comparative view of business metrics against set targets.

How to create a Mobile Dashboard with SQL Server Microsoft Mobile Publisher?

September 10, 2018 by

Over the past three years, I read some interesting news about Microsoft which was “Microsoft acquires mobile business intelligence leader Datazen”. This news made me excited because showing Reporting Service reports in mobile devices can be painful and often not effective for end users. After this acquisition, Microsoft developers worked quickly to adapt the Datazen application to SQL Server Reporting Services and this effort culminated in Microsoft SQL Server Mobile Report Publisher.

How to handle SSRS multi-value parameter filtering in SQL Server Parallel Data Warehouse

August 23, 2018 by

Experienced business intelligence (BI) developers would tell you that as you move from one project to another, some requirements start becoming repetitive like you have dealt with them before. One such repetitive requirement occurs during SQL Server Reporting Services (SSRS) development wherein a client would request that a report parameter be configured to allow multiple values from a dataset that is populated by stored procedure, as illustrated in Figure 1.

Dynamic Partitioning in Azure Analysis Services (tabular)

August 6, 2018 by

Objective

The real-life requirement

Disclaimer: I assume dear Reader, that you are more than familiar with the general concept of partitioning and star schema modeling. The intended audience is people who used to be called BI developers in the past (with a good amount of experience), but they have all sorts of different titles nowadays that I can’t keep up with… I won’t provide a full Visual Studio solution that you can download and just run without any changes or configuration, but I will give you code can be used after parameterizing according to your own environment.

SQL Server – development practices with referenced views

July 24, 2018 by

We’ve recently had production failures because our developers changed an important reference. In this case, we had a view which several procedures and views referenced. A developer made a change to the referenced view by removing columns, which caused several procedures and a view that referenced it to fail. We’re considering whether we should stop this practice, or if there are other ways we can prevent changes to an object that’s being referenced by other objects (in our case, a view).

Top 4 options for fixing Microsoft.AnalysisServices.AdomdClientUI.dll assembly error in SQL Server 2016

June 26, 2018 by

I’ve always been in favor of an orthodox strategy when it comes to applying SQL Server updates which often goes like:

  • Instead of installing SQL Server Cumulative Updates, wait for release of service packs
  • When a service pack is released, install it in phases starting from the non-production environment (i.e. DEV, UAT) to eventually roll it out on production

How to automatically create KPIs in SQL Server Reporting Services

June 18, 2018 by

Key Performance Indicator (KPI)

A Key Performance Indicator aka KPI is a metric which objectively measures the numeric equivalent of goals or targets of a company, team or an organization. Any individual or a community which has a numerical target can measure success of their goal with key performance indicators.

In all business roles and levels, if you manage a team you most likely have to set at least one key performance indicator and try influence this metric to show a positive result or trend. KPIs should be both logical and achievable. If not, team motivation and morale may decrease as a result of loss of self-confidence. For this reason, we have to be careful and logical when we set key performance indicators. At the same time, we have to check KPIs at regular intervals to determine if they remain valid. We can illustrate a typical KPI life cycle below.

How to integrate Power BI to the Facebook Graph API

May 4, 2018 by

The challenge

With the popularity of social networking and sharing sites and their widespread availability, internet marketing techniques have also been rapidly influenced. Sharing sites with high visitor traffic offers great potential for advertisers, so much so that it is almost unheard of now that brands or products do not have a profile or group on a social networking site. Markets have the opportunity to communicate directly with consumers by creating profiles or groups in sharing sites. Thanks to the comments and forums on the pages, they are able to follow both positive and negative attitudes of the target groups about themselves and thus have more precise ideas about what to do next.

4K resolution and high DPI: What you need to know about it to have great visuals

April 26, 2018 by

4K resolution, AKA Ultra HD, refers to a horizontal screen display resolution in the order of approximately 3,840 pixels. On two-dimensional display devices such as computer monitors, it represents display resolution of 3840×2160 pixels which is four times as many pixels as regular Full High Definition (1920×1080). What this means for users is the more pixels per inch (PPI) the higher resolution on the monitor. In other words, you can be closer to the monitor and still enjoy a crisp, clear picture.

How to configure OData SSIS Connection for SharePoint Online

April 13, 2018 by

As data warehouse developers, we often have to extract data from a myriad of source systems. Thus, whilst some source systems readily integrate with our ETL tools there are instances whereby we need to install additional drivers and software addons in order to successfully connect and extract data from other source systems. Microsoft SharePoint Online is one such source system that I recently had to extract data from and its connectors are by default not part of the standard SQL Server Integration Services (SSIS) package template. As SSIS developers we often don’t have solid background on environments such as SharePoint, thus figuring out which version of SharePoint Software Development Kit to install in order to enable successful connection from SSIS can sometimes be a frustrating experience. In this article, I try to alleviate some of that frustration by sharing some of my recent experiences relating to getting data out of a SharePoint list using SSIS.

How to migrate SQL Server 2017 Master Data Services Models into another server

March 23, 2018 by

Often as consultants, we don’t get to work onsite alongside our clients instead we are given copies of clients’ production environment and work on proposed solutions back at our offices. Once development has been completed, we then deploy and integrate our solution back to the client’s production environment. I’ve recently had to adopt a similar offsite development approach whilst working on a project that included development and configuration of master data services. In this article, I will demonstrate how a SQL Server 2017 Master Data Services (MDS) model can be exported from one environment (i.e. MDS Dev) and deployed into another environment (i.e. MDS Prod).

Automate documentation of SQL Server Analysis Server Tabular Model

March 13, 2018 by

There has been an ever-growing discomfort on documenting things especially when it’s very dynamic in nature and I was at one time undergoing the same. We have been developing SQL Server Analysis Tabular Model’s, which were quite a many in numbers and documenting 50 or 60 models manually is a big effort. In addition, development always demands change or enhancements that incurs changes on the documentation that is a continuous process. Adding the changes on the documentation is a time consuming process and sometimes loses track or remains inconsistent with the code built which is a critical issue when the system is in production for years.

I decided to automate the documentation of the SSAS model, to ease the manual effort here as well as save time. In addition, help the end users to see and review the latest change on the models quickly without even bothering the development team.

How to create advanced analytics using Power BI and R scripts

February 27, 2018 by

In this article, we will discover how to find the associations and hidden patterns in a dataset. The tool we will use for this is Power BI and not use any statistical functions or calculation.

Explanation

Power BI is one of the most powerful business intelligence solutions in the market. A cloud-based, user-friendly interface and basic development abilities provide this solution to be more convenient for people to use.

As you may know, Microsoft now supports R script in SQL Server and Power BI. R script support opens magical gates of statistics world to Power BI. Custom Visual offers very useful and interesting visual components for Power BI. In this store, many useful visualizations have been created by Microsoft or the community itself.
