Power Query is for Search, Connect, arrange,
normalize, access & transform
data & data sources
from internal data, external,
internet
Power Pivot is for
Easy data modeling and
preparing data for what you
want to see in your
visualization.
Sources are Excel table,
power query or data
connections to databases &
other services.

Stage 2
Analyze
• After adding the data to
data model this is what you
will get.
• At this stage relationships
can be established among
various data tables
• Each table appears as
separate worksheet in
power pivot
• Calculated columns can be
added.
• Calculated fields (explained
later) can be added.
“The PowerPivot database is a set of tables that are loaded in memory and saved into an
Excel workbook. When loaded in memory, these tables are viewed in the PowerPivot
window, not on Excel’s worksheets.”

Data
relationship
• Establishing Links among various tables is very easy.
• Each block represents one table having many columns and related columns can be simply dragged and joined.
• One to one relationships can be made by joining related columns from two tables
• So far the relationships support one to one relationship.
• For many to many relationships, a table with common records can be created and both columns can be joined to the
single or unique value table.

Calculated fields-
DAX
• Calculated fields can be added to a particular
table
• Flexibility of adding name and description of
the Calculated fields.
• Formula can range from simple multiplication,
subtraction to complex DAX queries
• Each formula can be assigned to a category like
percentage, Currency, date and general with
decimal points.
Stage 2
Analyze
• DAX formulas can be used either in PowerPivot
tables, or in PivotTables in Excel:
• Formulas can be used in calculated columns, by
adding a column and then typing an expression
in the formula bar in the PowerPivot window.
• Formulas can also be used in measures. You
create these formulas in Excel, by clicking
“Calculated fields” in an existing PowerPivot
PivotTable or PivotChart.

DAX Definition
DAX can be a simple formula as above where REVENUE is the table name and
[sell Net total] is the columns name
DAX can be a complex formula
like above which calculates
month to date revenue for the
selected context. The BLUE
highlighted items are called
functions.
What is DAX (Data Analysis eXpressions)?
“DAX is a collection of functions, operators, and constants that can be used in a
formula, or expression, to calculate and return one or more values. In other words,
DAX helps you create new information from data already in your model.”
Total revenue := (Revenue[Sell Net Total])+(Revenue[Fuel surcharge])
MTD Revenue Net
:=TOTALMTD(SUM([Sell
Net]),(Table1[Account Date]))
Yield := [Sum of Carrier revenue ]/[Sum of Weight Chargeable KG]
Previous Quarter Sales:=
CALCULATE(Revenue[Sell Net Total],
PREVIOUSQUARTER(Revenue[Account date]))
DAX becomes more complex by adding
calculate function which calculates the
figures for the selected context or slicer, or
by ignoring the context, depending on how
it is used.
Stage 2
Analyze
• The same formula can behave
differently depending on
whether the formula is used in
a calculated column or a
measure.
• In a calculated column, the
formula is always applied to
every row in the column,
throughout the table.
Depending on the row
context, the value might
change.
• In a measure (calculated
fields) however, the
calculation of results is
strongly dependent on
context. That is, the design of
the PivotTable and the choice
of row and column headings
affects the values that are
used in calculations.

in power view.
• The data can be arranged in power query and report
can be designed. This file can thus be used as a source
