Structured Storage• Powered by SQL Database• Supports rich querying capabilities• Dynamic Schematization• Data management in:• Azure Portal• SQL Portal (Silverlight)• SQL Management Studio• REST API• Azure CLI Tools• SQL CLI

The REST API
Action HTTP Method URL Suffix
Create POST /TodoItem
Read GET /TodoItem?filter=id%3D42
Update PATCH /TodoItem/id
Delete DELETE /TodoItem/id
Microsoft Azure
Base Endpoint: https://MobileService.azure-mobile.net/tables/*

JSON to SQL Type MappingsJSON Type T-SQL TypeNumeric values (integer, decimal, floating point)
Float(53)
Boolean bit
DateTime DateTimeOffset(3)
String Nvarchar(max)
Microsoft Azure
10
Auto-generated Columns• id – unique guid• __createdAt – date• __updatedAt – date• __version – timestamp
• Helps with concurrency and offline

Notification Hubs• Separate from Mobile Services
• Can be used regardless of whether you’re storing data in Azure• Extremely scalable push notifications• Cross platform support
• Push to iOS, Android, Kindle, Windows Phone, Windows Store• Tags (i.e. tie my registration to this topic or user ID)• Templates (i.e. when I get a push, send it in this format)• Connect to using Azure module
Microsoft Azure
Authorization&Authentication
21
Data Authorization• Per HTTP method auth options:
• App Key Required• Not ideal for production use
• Everyone• Authenticated Users• Admins and other scripts
• Requires Master Key as header• 400 Unauthorized response if security check fails

Scheduler
30
Scheduled Jobs• Executes a script on defined schedule• Can be run on demand• Ideal for any backend data processing job
Microsoft Azure
ScriptSourceControl
32
Script Source Control• Creates a Git repo in Azure• Access table, scheduler, custom API, shared scripts and
permissions• Pushing changes triggers a redeploy of your Mobile Service• Enables installing NPM modules
• Shared Scripts• Create scripts that can be used from all other scripts in your
Service
