MODEL-ASSISTED
Models used to understand or manipulate code
Examples: Static Structure, Sequence, …
MODEL-DRIVEN
Models executed by runtimes directly

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
Repository
Features
Repository catalog, secure views, auditing,
versioning, claims-based security, glob/loc, etc.
SQL Server
Features
system catalog, Change Data Capture,
replication, SSIS, mirroring, security, 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

“M” Language Example
// Module: Used to scope model definitions
module 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
// Module: Used to scope model definitions
module 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)
Compile
not null,
[LastName] nvarchar(100)
not null,
);

• 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

“M” Command-Line
Tools
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
