A LAP AROUND MODELING

What is a Model?A DESCRIPTION OF A GIVEN DOMAIN

MODEL-ASSISTEDModels used to understand or manipulate code Examples: Static Structure, Sequence, …

DRAWINGSModels used to communicate with othersExamples: Dataflow, Use Case, …

MODEL-DRIVENModels executed by runtimes directlyExamples: HTML, CSS, XAML, BPEL, …

SQL SERVER MODELING SERVICES

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 ServerFeatures

Repository catalog, secure views, auditing,versioning, claims-based security, glob/loc, etc.

QUADRANT

What is "Quadrant"?• Graphical tool used for managing instance

models– Targeted at architects and business analysts

• Loads model definitions from repository database– Allows management of instances– Changes are saved to database immediately

THE MODELLING LANGUAGE

Why “M”?• Interacting with Oslo content needs to be

simple and natural• Textural based modelling language

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

codename “m”: a language for data

“M” Language Example// Module: Used to scope model definitionsmodule Test.TimeReport{ // Type: Defines employee data structure type Employee { Id : Integer32 FirstName : Text where value.Count <= 100; LastName : Text where value.Count <= 100; } // Extent: Contains zero or more employees Employees : Employee*;}

MSchema is used to model data structures, storage, views and constraints

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 definitionsmodule Test.TimeReport{ // Type: Defines employee data structure type Employee { FirstName : Text where value.Count <=

100; LastName : Text where value.Count <= 100; }

// Extent: Contains zero or more employees

Employees : Employee*;}

create table[Test.TimeReport].[Employees]( [FirstName] nvarchar(100)

not null, [LastName] nvarchar(100)

not null,);go

Your Models

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

INTELLIPAD

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
