Introduction to Power BI• Microsoft cloud based Business Intelligence solution to analyze and

visualize data in a self-service way• Directly connect to all the important data using datasets, create

reports and share dashboards • Power BI Service (www.powerbi.com)• Visualize and analyze everything in one place using Power BI Dashboards and

schedule for data refresh

• Power BI Desktop• Import data from different sources and create custom reports and later

publish to Power BI Online Service

Demo on Power BI CapabilitiesDAX Functions• Date and Time Functions• Filter Functions• Information Functions• Logical Functions• Mathematical Functions• Statistical Functions• Text Functions• Time Intelligence Functions

Contd..Visualizations in Power BI• Doughnut Charts• Filled Maps• Waterfall Charts• Matrix• Standalone Images

Contd..Publishing Reports from Power BI Desktop• Directly publish your reports created in desktop tool to Power BI Service (

www.powerbi.com)

Groups & Content Packs• Groups in Power BI bring you and your colleagues together to collaborate,

communicate, and connect with your data• Package up and share your own dashboard, reports, and datasets with your co-

workers using content packs

Power BI Rest API Diagram

Power BI Rest API OperationsWith the Power BI REST API, you can:• Authenticate Power BI REST operations with Azure Active Directory

OAuth2 • Create and get datasets• Set a retention policy to automatically clean up old data• Get and update table schemas• Add and delete rows• Get groups

Contd..The Power BI REST API has the following operations:• Dataset operations: Get and create Datasets• Table operations: Get Tables and update Table schema• Row operations: Add Rows and delete Rows• Group operations: Get Groups

Supported Data Types

Automatic Retention Policy for Real-Time Data• The automatic retention policy in the Power BI service is a query

string parameter which enables a default retention policy to automatically clean up old data while keeping a constant flow of new data going into your dashboard

Power BI Rest API LimitationsThe Power BI REST API has the following limitations.• To POST Rows• 10,000 max rows per single POST rows request• 1,000,000 rows added per hour per dataset• 5 max pending POST rows requests per dataset• 120 POST rows requests per minute per dataset• 200,000 max rows stored per table in FIFO dataset• 5,000,000 max rows stored per table in ‘none retention policy’ dataset• 32,766 characters per value for string column in POST rows operation• Cannot Update/Delete specific row from a tablePOST Rows operation per Power BI plan• Dataset created by user with free service plan: 10,000 rows added per hour per dataset• Dataset created by user with paid service plan: 1,000,000 rows added per hour per dataset
