16 Sample Scenario – Multi-Tenant App -- Day#1 – Deploy CREATE DATABASE SalesDB GO CREATE FEDERATION CustomerFederation(cid BIGINT RANGE) GO CREATE FEDERATION ProductFederation(pid VARBINARY(64) RANGE) GO SalesDB member: Range [MIN, NULL) ProductFederation CustomerFederation

17 Sample Scenario – Multi Tenant App -- Connect to the federation member USE FEDERATION CustomerFederationeration(cid = 0) WITH FILTERING=OFF, RESET GO CREATE TABLE [dbo].[Customer]( [CustomerID] [bigint] NOT NULL, [Title] [nvarchar](8) NULL, … CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED ([CustomerID] ASC) ) FEDERATED ON (cid = CustomerID) GO CREATE TABLE [dbo].[CustomerAddress]( [AddressID] [int] NOT NULL, [CustomerID] [bigint] NOT NULL, … CONSTRAINT [PK_CustomerAddress] PRIMARY KEY CLUSTERED ([CustomerID],[AddressID] ASC) ) FEDERATED ON (cid = CustomerID) GO CREATE TABLE [dbo].[PostalCode]( [PostalCodeID] [int] NOT NULL, [PostalCode] [nvarchar](15) NOT NULL, … CONSTRAINT [PK_PostalCode] PRIMARY KEY CLUSTERED ([PostalCodeID] ASC) ) GO SalesDB member: Range [MIN, NULL) CustomerFederation Customer (federated) CustomerAddress (federated) PostalCode (reference)
