What is SMOWhat is SMO
SQL Server Management ObjectsProgrammatic object model for DDL operationsUse it for creation, management, discovery, configuration of Sql Servers.NET Class LibraryNot a total abstraction of Sql Server

Some of the Design GoalsSome of the Design Goals
100% coverage of Sql Server featuresImprove scalability and performanceSimple to use, but rich object modelHigh level of control over object model behaviorAdvanced scripting capabilitiesBuild SQL Server Workbench on it

Feature OverviewOptimized InstantiationFeature OverviewOptimized Instantiation
Instance Classes support “optimized (delayed) instantiation”
Object states 1: Partially instantiated (some properties available)2: Fully instantiated
Full instantiation is triggered when a property is called that has not been retrieved yet, or when a method is called that requires a missing property

All Transact-SQL generated by performing actions on SMO objects can be captured or recorded
This is NOT transactional, it is only capture
WorkBench Dialogs use this capability to script operations
