Raw data have to be correctly sourced and processed (cleansing, aggregation, etc). Then they can be transformed into information (e.g. the most costly part of the portfolio) and knowledge (the reasons behind this). Knowing the causes of the problem we can take appropriate actions. The more efficient the process is the better-taken decisions are.
Microsoft Power BI is a suite of tools that supports the process of data processing - from sourcing to suggesting optimal decision.
Below the list of the most popular data sources, you can connect with using Power BI connectors:
- Files (e.g. excel .xlsx, .pdf, .csv, .xml, .json)
- Data Bases (e.g. MS SQL, Oracle, SAP HANA, PostgreSQL, MySQL, Amazon Redshift, Snowflake, others)
- Folders (cloud-based e.g. SharePoint and locally-based)
- Azure Services (Azure SQL Database, Azure Blob Storage, Azure Data Lake, others)
- On-line Services (e.g. Microsoft Exchange, Dynamics 365, Salesforce Objects, Google Analytics)
- Other Sources (e.g. websites, OData feed, ODBC, Active Direcory, others)
- Indirect connection via other services (e.g. Microsoft Azure Data Factory)
The data is processed and transformed with Power BI queries (M language) to the so-called data model.
Then, with the use of DAX formulas, the data objects formulas, the data objects (e.g. KPI's, targets, etc.)
that need to be part of a Power BI report are created (measures, calculated columns, parameters).
When a Power BI report is ready, you can analyse it using one of the Power BI versions:
- Power BI Desktop
- Power BI Service
- Power BI Mobile
Power BI Desktop
A desktop version of Power BI (free download from Microsoft website). It is the most complex version of Power BI that allows us to get data from different sources and process them. It also allows users to create dynamic reports that can be easily analysed. It creates .pbix files that contain the data model (aggregated data) and the report. It is a proper choice for people who work with raw data and prepare reports.
Power BI Service
It is a cloud version of Power BI. It allows us to get pre-processed data and prepare reports. It is not as complex as Power BI Desktop however it allows us to cooperate with others and share the reports with people without Power BI Desktop installed on their computers. You can easily transfer reports between a desktop version and a cloud version. If you would like to know more about the Power BI cloud version, licenses, and subscriptions, please read our article on Power BI licensing.
Power BI Mobile
It is a version dedicated to mobile devices like tablets and smartphones. It allows a convenient analysis of reports - any time and any place.

There are a few reasons behind the growing popularity of Power BI:
- Reporting Process automation
- Connecting different sources of data in one data model (one source of truth)
- Interactive, multidimensional reports, possibility to track correlation
- Quick and easy analysis
- Standardization and reliability (lower risk of "human error")
- Collaboration and safe report sharing with any member of the organization
