• Importing data from CSV files: Configuring delimiter settings and handling data formatting

For this lesson we will use the miles per gallon (mpg) dataset available at https://raw.githubusercontent.com/bpkindo/datasets/main/mpg.csv

Basic DAX Formulas

Importing data from excel to Power BI Desktop.
The data we use for this data is the AdventureWorks sample data available at https://github.com/bpkindo/datasets

Installing SQL Server, SQL Server Management Studio and AdventureWorks sample database

• Introduction to the integration between Power BI and SQL Server: Benefits and scenarios
• Connecting Power BI to SQL Server: Importing data from SQL Server databases

Often relational databases contain large amount of data that it may not be appropriate to import the entire table to Power BI. In such cases, we summarize data using SQL code, utilize the advanced option to import data to Power BI

- DirectQuery in Power BI: Configuring DirectQuery mode and utilizing SQL Server as a DirectQuery source
- Understanding performance considerations and limitations
- When to use DirectQuery and Import

• Importing data from various sources: Databases, web, SharePoint, and other data connectors

SQL programming language is one of the most widely used languages in data analytics. This exercise gives you a very brief overview of few of the most commonly used SQL clauses.

Exploring the Power Query Editor interface: Query settings, query steps, and applied transformations

Hands on exercise cleaning and merging data using Power Query Editor

Continue learning the data cleaning capabilities of Power Query Editor

Replacing Values, Filling Values, and Unpivoting

In this lesson we will learn how to combine multiple queries/tables into one by appending them with each other

Data analysis often requires joining one table to another one. In this lesson we will discuss how you can join/merge two Power BI queries/tables.

It is important to assign correct data types to Power BI datasets. In this lesson we will illustrate issues that could arise when correct data types are not used.

- Briefly discuss adventureworks database used as illustration
- Autodetect relationships
- Manage relationships that is autodetected, or create relationships if not autodetected
- Introduced 1 to many relationship - cardinality
- Other topics discussed:
o Import two tables sales, and customer table
o Introduce the concept of fact table vs. dimension table that we will discuss in future lessons
o Expose students to concepts of surrogate key, and foreign key

We investigate the role of relationships in Power BI Data modeling

Cardinality of relationships
- 1 to many relationship
- many to 1 relationship
- 1 to 1 relationship

Active vs. inactive relationships

A star schema is a way to organize data easy analysis. It uses two main table types: fact tables store the measurable data, like sales amounts, and dimension tables contain descriptive attributes like product details or time. The fact table sits in the center, like a star, with dimension tables branching out, connected by foreign keys. This structure allows for fast querying and analysis of large datasets by letting you slice and dice the data based on different dimensions.

• Designing effective report layouts: Organizing visuals, utilizing pages, and managing interactions
• Applying report-level filters: Filtering visuals based on specific criteria or user selections

The purpose of an analytic report is to communicate data insights. Following basic design principles such as placement of charts, aesthetic balance, and contrasts aids in achieving such objective.

This lesson explores some design principles to consider when authoring Power BI reports.

• Cards
• Pie Charts
• Donut Charts
• Bar charts
• Column Charts

Exploring area charts and ribbon charts

Practice exercise to create a report for an animal shelter. Instructions for the exercise are in the power point file.

Table and matrix visuals allow us to show multiple metrics of multiple data slices in one visual.

We will learn how to create these visuals in Power BI and how applying conditional formatting can help report consumers quickly understand relationships.

Illustration of calculating columns using DAX

Understanding row context and filter context used in DAX calculations

Introducing simple DAX functions that take only one argument/input.

DAX Iterator functions like SUMX, AVERAGEX, RANKX, etc are explored

Illustration of how we can modify a filter context using CALCULATE() DAX function

In this lesson we discuss the DAX function RELATED using a practical example

Illustration of the DAX function RELATEDTABLE() and highlight is difference from the DAX function RELATED.

We continue to discuss several commonly used DAX functions
