Introduction to Power BI

Power BI is the newest Microsoft Business Intelligence and Data Analysis tool. In this module we will go through basics of this product, and introduce all five components of Power BI (Power Query, Power Pivot, Power View, Power Map, and Power Q&A). You will see some demos and introduction about Power BI desktop, Office 365 Power BI subscription, and Power BI website, and mobile apps. You will see some basic demos of how easy to use is Power BI in some scenarios.

Lessons

Power Query for Data Transformation

Data analysis and BI world starts from data extraction and transformation. Power Query is the data transformation engine of Power BI. Power Query comes as part of Excel 2016, or as an add-in for Excel 2013 and 2010. Power Query is also part of Power BI Desktop. In this module you will learn about all different version of Power Query, their similarities, and differences, as well as configuration and requirements of using them. Power Query uses a graphical user interface to apply transformations on the dataset. However Power Query works with a functional scripting language behind the scenes. The key to learn Power Query is learning the functional language called M. There are many features in M that are not available in the Power Query GUI. In this module you will learn how to understand M, and how to write M scripts even from scratch. You will learn writing custom functions in M as well as many other useful features.

Lessons

Data Modeling

Power Pivot is xVelocity in-memory data modelling engine of the Power BI. Modelling effectively is the key of high performance BI solution. In this module you will learn basics of Power Pivot such as creating relationships, and calculated members, as well as advanced best practices and DAX expressions. DAX is Data Analytical eXpression language. DAX has similar structure to excel functions, but it is different. In this module you will learn DAX from beginner to advance. You will learn basic functions as well as complex functions and scenarios of using them in real world challenges.

Lessons

Learning DAX

DAX, or Data Analysis eXpression is the language for querying and creating calculated measure and columns and tables in Power BI, SSAS Tabular, and Power Pivot. So one of the critical learning path for Power BI is learning DAX. In this lesson you learn basics of DAX and also some examples of using time intelligence functions in real world.

Lessons

Data Visualization

Data Visualization is the front end of any BI application, this is the user view point of your system. It is critical to visualize measures, and dimensions effectively so the BI system could tell the story of the data clearly. In this module you will learn conceptual best practices of data visualizations which is valid through all data visualization tools. You will learn Power View and Power Map skills. Power View is the interactive data visualization tool and Power Map is 3D geo-spatial data visualization tool. You will learn how to create effective charts, and dashboards using these tools as well as best practices for working with these tools. There are two version of Power View; Power View for Excel, and Power View for SharePoint which will be covered in this module as well.

Lessons

Designing the best solution with Power Q&A

Power BI introduced a new engine for users which focus on users who wants to play with the data more, and understand the story behind the data better. Power Q&A is question and answering engine which works based on human natural language. Power Q&A automatically will be enabled on Power BI files deployed into Power BI website, or Office 365 subscription. However there are some tips and tricks about how to design your model to get the best type of answers through Power Q&A. In this module you will learn best practices for modelling that effect on the response of Power Q&A.

Lessons

On Premises Data Access with Gateways

Power BI can connect to cloud data sources and also on-premises data source. For on-premises connection you need to install and configure gateways on the on-premises servers or machine, and Power BI creates the connection based on that. In this module you learn about different types of gateways and how to set up them for an on-premises data access from Power BI.

Lessons

Security

In this module you will learn how to use work groups and sharing in Power BI to share dashboards, reports, and data set within Office 365 group. You will also learn how to implement row level security in different levels. You will learn implementing row level security in Power BI Desktop, or in a data source of SSAS Tabular Live connection, or dynamically.
