Microsoft’s Vision

3 DUBS ( A QUICK SPIN )

blackmarble

3 Dubs

• WCF 4.0

• WF 4.0

• “Dublin” Application Server

Version Integration

.net 3.0 WCF | WF

.net 3.5 WCF + WF

.net 4.0 WCF/WF

blackmarble

WCF 4.0

• Services can be declared using XAML

– You can create a service with zero lines of

code

• Much tighter integration with WF

• Tighter integration with Dublin

blackmarble

WF 4.0

• Core WF class library has been re-written

• Flowchart workflow model

• 10x – 100x performance increased

• XAML has been greatly improved

– XAML is now default authoring mode

• Designers have been re-written to use WPF

– 10x easier to add activity designers

– You may love it, you may hate it

• Designer re-hosting is 10x easier

blackmarble

Windows Application Server Extensions(Codename “Dublin”)

• Evolution of WAS/IIS

and Windows

App Server role to

run and manage WF

and WCF services

• Initial release is

a web download

• Ships soon after VS10Windows Server

Dublin vs. BizTalk

BizTalk Dublin

$34,999 per proc ($8,499 Std Edn) Free

Hosts message channels and

orchestrations

Hosts services and workflows

Uses message box for highly

reliable messaging

WS-RM can be used, messages

not persisted

Fully supported for large scale

deployments

Scaled in the same way as IIS

Comprehensive management and

diagnostics tools

Basic management and

diagnostics tools

Latency can be an issue as

messages are persisted

Low latency achieved easily

THE REPOSITORY

blackmarble

Repository

• A single location for definitions

• A single location for information

• Relationships defined across traditional

boundaries

• End to End tracking

Schema Instance

blackmarble

Repository Capabilities

• Repository features are built on SQL Server– Repository install also turns on useful

features, e.g. replication and mirroring

system catalog, Change Data Capture,

replication, SSIS, mirroring, security, etc.

SQL Server

Features

Repository catalog, secure views, auditing,

versioning, claims-based security, glob/loc, etc.Repository

Types of Models

• Structural Models

– Model definitions

– Represented by table structure

• Instance Models

– Model instances

– Represented by data in structural model

tables

blackmarble

Structural Models

• Database structure is used to define

models

• E.g. WCF artefacts are represented as

tables in the repository database

– Service contracts

– Operation contracts

– Endpoints

– Bindings

blackmarble

Repository Database Content

• Tables in the Repository

database represent

different technologies

• Currently included:

– Common language runtime

– Windows Communication

Foundation

– Windows Workflow

Foundation

– Identity

blackmarble

System.ServiceModel partial structure

blackmarble

Instance Models

• Data is used to define models

• Rows are inserted in structural model tables

• A service application can be modelled by– Adding a service

contract

– Adding service operations

– Adding endpoints and bindings

blackmarble

Federating Systems

• The repository may be federated across other

data stores such as

– Team Foundation Server (TFS) in Visual

Studio Team System

– Various stores in System Center

– And more

• Imagine the possibilities

blackmarble

Repository Summary

• Repository is optimized for many reads,

few writes

• Contains models for “Oslo” app domains

• Can be extended with M

• Models can be deployed, secured

and versioned

blackmarble

THE MODELLING LANGUAGE

blackmarble

Why “DM”?

• Interacting with Oslo content needs to be

simple and natural

• Textural based modelling language

blackmarble

What Is “M”?

• “M” is a language for defining domain models and textual domain-specific languages (DSLs)

• M domain models define schema and query over structured data– Values, Constraints, and Views

– Natural projection to SQL

• M DSLs define projections from Unicode text to structured data– Rule-based transformation

– Grammar-driven text editor integration

“M” Language Example// Module: Used to scope model definitions

module Test.TimeReport

{

// Type: Defines employee data structure

type Employee

{

Id : Integer32 = AutoNumber();

FirstName : Text where value.Count <= 100;

LastName : Text where value.Count <= 100;

} where identity (Id);

// Extent: Contains zero or more employees

Employees : Employee*;

}

MSchema is used to model data structures,

storage, views and constraints

blackmarble

Using “M” to Model a Database

• Once they’re in the database, it’s just SQL

• “TSQL can be used to create repository structure

or standard database structure

– Repository TSQL is more complex

// Module: Used to scope model definitions

module Test.TimeReport

{

// Type: Defines employee data structure

type Employee

{

Id : Integer32 = AutoNumber();

FirstName : Text where value.Count <= 100;

LastName : Text where value.Count <= 100;

} where identity (Id);

// Extent: Contains zero or more employees

Employees : Employee*;

}

create table

[Test.TimeReport].[Employees]

(

[Id] int not null identity,

[FirstName] nvarchar(100) not null,

[LastName] nvarchar(100) not null,

constraint [PK_Employees] primary key clustered ([Id])

);

What “M” Is Not

• An object-oriented language– No polymorphism, virtual dispatch

– “Is-a” determined based on structural subtyping, not stipulation

• A data access technology– M domain models compile down to T-SQL

– Tool chain supports course-grained loading/unloading of schemas and values – not an OLTP solution

• A replacement for T-SQL– Far less expansive feature set

– Tool chain supports linking/invoking T-SQL

blackmarble

Learning “M”

• Oslo SDK

– Available for download

• The “Oslo” Modelling Language

– Langworthy, Lovering, Box – Addison-Wesley

• Learning MSchema will take a C#

developer about a day

blackmarble

INTELLIPAD

blackmarble

IntelliPad Editing Tool

• Simple text based code editor

• Supports “M” languages

• Provides instant feedback of code

compilation

– Great for learning “M” languages

• Visual Studio can also be used for “M”

– Most likely scenario in real projects

QUADRANT

blackmarble

What is "Quadrant"?

• Graphical tool used for managing instance models

– Targeted at architects and business analysts

• Uses “Office Style” ribbon toolbar

– Everyone uses office

• Loads model definitions from repository database

– Allows management of instances

– Changes are saved to database immediately

Oslo Scenario: Modelling an

application• Design

– “M” is used to define the application database structure

– The “M” model is imported to Repository database

– The application is modelled in Quadrant

• Implementation– The “M” model is used to create the runtime database

– Visual Studio is used to develop runtime components

• Deployment– Quadrant could be used to deploy the application

• RunTime– “Dublin” could be used to deploy the application

SUMMARY

blackmarble

Summary Oslo – September 2008

• Repository Database– Built on SQL Server 2008

– Stores model definitions (structure)

– Stores model instances (data)

• “M” language– Declarative text-based modeling language

– Aimed at “curly-brace” programmers

– Can be used to define models for repository database
