Problem

Solution EMF

Problem

“60 – 70% of software applications does not meet customer requirements”

Customer is unhappy because,

• Defective Software Applications• Delayed Projects• Poor Design• Inefficient Architecture

Consequence!

“Increased Living Cost!”

Reasons

“Complexity”

Why Complexity?

• Ever Changing Requirements• Shorter Release Cycles• Increasing Lines of Code• Software Product Families• More Software Technologies

Solution!

• Assembly Language • High Level Languages• Object Oriented Programming• Component Based Systems• What is Next?

MDSD(Model Driven Software Development)

Model?

“Model is a description of the system”

MDSD?

“Generate a Software Application from the model”

MDSD?

Model Software Application

NO!

MDSD!

Generate 60-70% of App!

Where is MDSD!

Is it Available as a Framework?

NO!

Where is MDSD!

MDA

MOF

MDSD

• MDA = Model Driven Architecture• MOF = Meta Object Facility

EMF?

EMF = MDA + MOF + MDSD Concepts!

What does that mean?

Software Application

EMF?
