Setting Up The Project
Clock-wise rule of thumb
1. Configure Model.bim properties
2. Configure Project Properties
3. Import from Data Source
(Don’t forget to add the Solution to Source Control)

15. #SQLSatLima
Mejoras para el UX
1. Marking date table as
date
2. Column Properties
a. Column Name
b. Date Format
c. Data Type
d. Description
e. Hidden
f. Sort By Column
g. Data Category
h. Default Field Set
i. Default Image
j. Default Label
k. Keep Unique Rows
l. Row identifier
m.Summarize By
n. Table Detail Position

16. Consultando con DAX

EVALUATE
[DEFINE
{MEASURE <tableName>[<name>] =
<expression>}
EVALUATE <table>
[ORDER BY {<expression> [{ASC | DESC}]}[,
…]
[START AT {<value>|<parameter>} [, …]]]
Retrieve data from table expression.
T-SQL
Equivalent
SELECT * FROM <table>
Note Formatting configured in Tabular Model is lost

18. #SQLSatLima
EVALUATE
is similar to
SELECT * FROM [dbo].[FactInternetSales]
EVALUATE
'InternetSales'

19. #SQLSatLima
EVALUATE

20. #SQLSatLima
SUMMARIZE
SUMMARIZE(<table>, <groupBy_columnName>[,
<groupBy_columnName>]…[, <name>,
<expression>]…)
Returns requested aggregated values over a set of groups
T-SQL
Equivalent
SELECT <columns>, <aggregated columns> FROM <table>
GROUP BY <columns>
Type Statistical Function

21. #SQLSatLima
SUMMARIZE
is similar to …
EVALUATE
SUMMARIZE (
'InternetSales',
'Product'[Product Name],
"Sales", SUM ( 'InternetSales'[Sales Amount] ),
"Revenue", 'InternetSales'[Revenue]
)

22. #SQLSatLima
SUMMARIZE
SELECT
p.[EnglishProductName],
SUM(f.[SalesAmount]) AS Sales,
SUM(f.[SalesAmount] - f.[ProductStandardCost] -
f.[Freight] - f.[TaxAmt]) AS Revenue
FROM [dbo].[FactInternetSales] f
INNER JOIN [dbo].[DimProduct] p
ON p.[ProductKey] = f.[ProductKey]
GROUP BY
p.[EnglishProductName];
