Basics of Microsoft Power Business Intelligence (BI)

Visualizing data and sharing it among the consumers inside your organization has more value than having data in database servers. Although the availability of data is important, to be able to visualize all aspects of the data serves the bottom line of an organization is more important.


PowerBI makes it possible to not only visualize data but helps you make quick decisions. PowerBI allows you to connect to data from a wide variety of data sources, both traditional database servers but also from online data; it creates a model and then you start exploring data in a variety of ways, producing a wide array of graphs and presentation which you can publish, share or collaborate.


PowerBI targets naïve, intermediate and advanced users. PowerBI has capabilities built to accommodate all experience levels.


This course however, is aimed at beginner users with limited data experience enabling you to adhoc-visualize data and generate reports. Specifically, you will have an introduction to PowerBI Desktop, one of the PowerBI products, and see how to access data and visualize it from a couple of sources. Although the course is partly hands-on, it is meant to provide an introduction to the topic.

Introduction to Data Analysis

Introduction to Data Analysis sets a foundation for those interested in pursuing more advanced topics in data analysis.

Becoming a data analyst requires proficiency in several areas:

  • Data wrangling
  • Programming
  • Statistical methods
  • Machine learning
  • Data visualization

There is truly a vast amount of open data available to anyone who knows where to find it, but data is often found in a form that does not lend itself to analysis.

Data wrangling is the use of tools and techniques to transform unstructured data into structured data from which descriptive, predictive, and prescriptive analytics can be derived. Business leaders depend on high-quality, real-time analytics to make informed business decisions. This "business intelligence" enables a company to differentiate itself from its competition, but high-quality, real-time analytics is the end game. One has to walk before they can run. Data analysts often point out that roughly 70% of their work involves data wrangling.

This course sets you on a successful path in data analysis by building a solid foundation. A course will follow that introduces learners to machine learning via Microsoft Azure Machine Learning Studio.

Recommended preparation: Algebra and basic statistics. No programming experience is required - the necessary R programming will be learned in the context of working with data sets.
