DATA
PREPARATION
IN POWER BI
Data preparation is a crucial step in
the process of creating useful insights
from data. Power BI's Query Editor
provides a robust set of tools for
importing, transforming, and cleaning
data from a variety of sources.

DATA
MODELING IN
POWER BI
Data modelling is the process of
creating a data model that represents
the relationships between different
tables in a dataset. Power BI provides
a powerful data modelling engine that
enables users to create complex data
models.
CREATING RELATIONSHIPS
BETWEEN TABLES
SETTING UP
HIERARCHIES
Hierarchies are a way to organise data
into a tree-like structure that can be
used to navigate and filter data in a
report. Users can create hierarchies in
Power BI by selecting the relevant
columns and dragging them into the
hierarchy fields.
CREATING CALCULATED
MEASURES
Calculated measures are a way to
perform calculations on data in a
table or column.
Users can create calculated
measures in Power BI by using
the DAX language, which is a
powerful formula language that
enables users to perform
complex calculations.
ADVANCED DATA
MODELING CONCEPTS
DAX formulas
Time
Intelligence
Data Analysis
Expressions
(DAX)
By leveraging these advanced data modelling concepts, users can create
more sophisticated data models that enable them to perform deeper
analysis of their data.

BEST
PRACTICES
FOR DATA
MODELING
Use meaningful column
names
Avoid circular
dependencies
Optimise data types
DATA
VISUALIZATION
IN POWER BI
Data visualisation is the process of
representing data in a graphical
format, such as charts, tables, maps,
and gauges, to enable users to
understand complex data quickly.
Power BI provides a wide range of
visualisation options that enable users
to create interactive, visually
appealing reports.
CREATING TABLES AND
CHARTS
Tables and charts are the most
common types of visualisations
used in Power BI.
Users can create tables and
charts by dragging and
dropping fields onto the
canvas.
Power BI provides a range of
chart types, such as column
charts, bar charts, line charts,
pie charts, and scatter charts.
CUSTOMISING
VISUALISATIONS
Power BI provides a range of
formatting options that enable users
to customise visualisations. Users can
change the colour scheme, font size,
font type, and background colour of
visualisations to make them more
appealing. Users can also apply
themes to visualisations to ensure
consistency across the report.

BEST PRACTICES FOR
DATA VISUALIZATION
To ensure that visualisations are effective, it's important to follow some best
practices when creating visualisations in Power BI:
Choose the right
visualisation
Use consistent
formatting
Keep it
simple
Provide
context
