A LAP AROUND MODELING

Slide 8

What is a Model? A DESCRIPTION OF A GIVEN DOMAIN MODEL-ASSISTED Models used to understand or manipulate code Examples: Static Structure, Sequence, DRAWINGS Models used to communicate with others Examples: Dataflow, Use Case, MODEL-DRIVEN Models executed by runtimes directly Examples: HTML, CSS, XAML, BPEL,

Model-driven Applications Textual domain specific language (CAML) Visual designer (SharePoint Designer) Application definition stored in database Textual domain specific language (X++) Visual designer (MorphX) Application definition stored in database

THE MODELLING LANGUAGE

Slide 24

Why M? Interacting with Oslo content needs to be simple and natural Textural based modelling language

Slide 25

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
