Azure Synapse Analytics > SQL >

Overview
A materialized view pre-computes, stores, and maintains its
data in Azure SQL Data Warehouse like a table.
Materialized views are automatically updated when data in
underlying tables are changed. This is a synchronous
operation that occurs as soon as the data is changed.
The auto caching functionality allows SQL DW Query
Optimizer to consider using indexed view even if the view is
not referenced in the query.
Supported aggregations: MAX, MIN, AVG, COUNT,
COUNT_BIG, SUM, VAR, STDEV
Benefits
Automatic and synchronous data refresh with data changes
in base tables. No user action is required.
High availability and resiliency as regular tables
Materialized views
-- Create indexed view
CREATE INDEXED VIEW Sales.vw_Orders
WITH
(
DISTRIBUTION = ROUND_ROBIN |
HASH(ProductID)
)
AS
SELECT SUM(UnitPrice*OrderQty) AS Revenue,
OrderDate,
ProductID,
COUNT_BIG(*) AS OrderCount
FROM Sales.SalesOrderDetail
GROUP BY OrderDate, ProductID;
GO
-- Disable index view and put it in suspended mode
ALTER INDEX ALL ON Sales.vw_Orders DISABLE;
-- Re-enable index view by rebuilding it
ALTER INDEX ALL ON Sales.vw_Orders REBUILD;

What Happens to Existing Azure SQL
Data Warehouse?
Its not going “away”
Current SQL Data Warehouses will continue
Azure Portal will soon display “Synapse SQL Pool”, which is more accurately named
◦ SQL Pool
◦ SQL On-demand
◦ Spark Pool
◦ Code Artifacts
◦ Metadata

Data Is Ready- Now What?
Push to Azure DB
Leave in Azure Data Lake Storage
Connect to Analysis Services for Multi-dimensional Modeling
Power BI for final modeling and visualizations/reports/dashboards/apps
Use third party tools with data

What Kinds of Visualizations?
Choose from numerous modern visualization types:
◦ Filter data:
◦ Slicer
◦ Display numeric values:
◦ Card, Multi Row Card, Table, Matrix, KPI
◦ Graphically visualize data:
◦ Bar, Column, Line, Combo, Scatter, Waterfall, Pie, Donut,
Funnel, Treemap, Gauge, R Script
◦ Spatially visualize data:
◦ Map, Filled map, Shape map (preview)
https://powerbi.microsoft.com/en-us/developers/custom-visualization/

Custom Visuals
Custom visuals can be imported to extend beyond the out-of-the-box visualizations
◦ A gallery of visuals created by the Power BI community is available at https://app.powerbi.com/visuals
◦ Browse through the visuals or submit one of your
own for others to use
◦ The list of available visuals is growing each month
◦ Custom visuals will render in the Power BI service

Designing reports
Custom visuals: Gallery (subset)
* And the list
is growing!

What Data
Sources
Can Power
BI Connect
TO?
Over 100 different data sources
What is available in the service may be
be different than the desktop
If hybrid connection, (on-prem/non-
Azure cloud) the Power BI Gateway
will be required

Get [A LOT
OF] Data
**Custom connectors can also
be created.

Modeling Data
Work in Data View to inspect, explore, and understand data in the
model
 It is a different experience from how you can view tables, columns, and
data in Query Editor
 This is a view of the data after it has been loaded into the model

Creating
Calculated
Columns
Created from Data View in Power BI
Aggregate data
Combine columns to create unique identifiers

Measures
Uses DAX, (Data Analysis Expressions)
Over 200 functions, operators and constructs
Incredibly flexible
Similar to Excel formulas, (MDX) but designed to work with relational data

KPIs
Key Performance Indicators, (KPIs) also called
“strategic measures”
◦ Helps understand if company goals are being
achieved
◦ Goal values must be part of the dataset in Power BI

KPI Demonstration
Choose the data
Choose the timeline for the KPI
Sort by the indicator
Change to a KPI visual
Update any fields

Performance Analyzer
In Power BI Desktop
Open Report
Start Recording
Optimize for Time

Turning on
Previews
This changes every release,
so update what previews
you’d like to try out!

Row Level Security
Excludes data from visualizations and reports
Is set up at report level
Uses DAX Filters
Filters assigned to roles
Assigned to users and groups through roles
Admins can test out roles before releasing to
production

Power BI Gateway
The Power BI Gateway—Personal is used to refresh supported on-
premises data sources
 Only available in 64-bit
 Runs as a service if configured with an administrator account;
otherwise runs as an application
 Data transfer is secured (SSL) through Azure Service Bus
 Often no requirement to open firewall ports, (unless VM installation)
 Certain scenarios cannot be scheduled for data refresh:
 Custom SQL statements
 Excel worksheet data
 Direct Connect or DirectQuery data sources

Power BI Gateway- Enterprise
Installation of the On-Premises Data Gateway serves large groups of users
to refresh supported on-premises data sources
 It is the successor to the Power BI Gateway—Enterprise
 IT can:
 Centrally manage the set of users who have access to the underlying data
sources
 Gain visibility into gateway usage, such as most commonly accessed data
sources, and the users accessing them
 Data sources:
 SQL Server Analysis Services
(Multidimensional and Tabular modes)
 SQL Server
 Oracle, Teradata, SAP HANA…

the world.

Content Packs to Apps- Why?
Allows for distinct collection of reports/dashboards/visualizations
One link to access them all vs. searching
Package and distribute
Notifications, alerting and row level security

Creating a Content Pack/App
Significantly Easy
No Code Solution
Allows you to share multiple reports/dashboards/datasets with groups/users
Can embed URL to other applications

Summary
Power BI has extensive visualizations, reporting and
dashboard analytics features
Ability to pull data from over 100 data sources
As part of the larger analytics solution with Azure
Synapse Analytics, an enterprise solution for
analytics, IOT and machine learning can be created
with ease.
