Everything from academic research to decision making in businesses is now driven by data. Data, alone, can be overwhelming though, if you have a lot of it. It is here where Microsoft’s Business Analytics product Power BI comes into play. Customers can then turn complex information into useful information using easy to read reports and visualizations. Its your data superhero, turning raw data into knowledge with meaning so that you can make smarter decisions. Sounds good, doesn't it?

What Does Power BI Do?

With Power BI, you can:

a. Connect to different databases, Excel and even to online services like Google Analytics.

b. Visualization can be done using several graphs, charts and maps, which are graphical representations.

c. Allow providing access to dashboards and reports for your workmates to team up.

Knowing Power BI will help stand out from the competition if you work in IT, business management or any other data driven sector at OptionTrain College of Management & Technology.

Breaking down key Power BI terms

Now the key ideas you’ll come across when using Power BI will be easier. The components of the tool are as follows:

1. Dataset

Think of our dataset as being your data store. It is where all your data lives, and where those come from your cloud services such as Salesforce, or Excel sheets and SQL Databases. Once this can be connected to Power BI, you start seeing 'associative patterns,' though I don't mean the word 'pattern' in its conventional sense.

Example: Suppose you run a retail business and you record your sales in Excel. Your dataset in Power BI is an Excel document.

2. Report

A report is a series of visuals (graphs, charts, maps) using your data to tell a story. Each report can include a number of "pages" or tabs, just like an Excel spreadsheet. With reports, you can dig into your data a little bit deeper for more insightful details.

Example: For example, if you wanted to do a report that showed, on a line chart, sales over time and on a bar chart, sales by location to demonstrate how your store sales are increasing.

3. Dashboard

Dashboards are a fast overview of your most important metrics. It shows a single page with visual summaries from one or more visualizations. A report is generally more dynamic than a dashboard and gives you the opportunity to go deeper.

Example: They will be able to create a dashboard displaying the sales data in one place because the CEO of their store may not have time to dig in and review all of the data.

4. Visualization

All it truly is, is a fancy word for the maps, graphs, charts and other visual pictures that depict your data. Power BI has a good variety of visual experience: from basic bar charts to complex waterfall charts and global maps.

Example: For example, pie chart might be used to show percentage of total sales generated by each type of products.

5. Power Query

Power Query in Power BI is a tool that lets you clean, shape, and transform your data before you demonstrate it. Power Query would definitely be your toolbox if you are a detective because it would find and organize the evidence (data) you need to solve the case and produce meaningful conclusions.

Example: Clean up dirty data on your Excel sheet before visualizing with Power Query, so you don’t have to waste time finding and cleaning up missing values or errors initially.

6. Filters

Filters allow you then to focus on specific insights by narrowing down the data. We may filter reports, dashboards or any particular visual.

Example: All you want to see is data for a particular area of the store. You may filter your report to see just the sales figures for that region.
