Model-Driven Development

a range of development approaches that are based on the use of software modeling as a primary form of expression

... yield higher levels of abstraction in software development

… Combined with executable semantics this elevates the total level of automation possible

3 reasons why we chose Code Generation (of Java Web applications)

execution environment is as standard as possible: standard architecture, standard libraries

customer can choose its preferred execution environment: an open source application server: tomcat, jboss, glassfish a commercial application server: ibm websphere, oracle as a cloud JEE service: amazon ec2

two degrees of freedom instead of one managing the Visual Identity

Same model with different generation rules (e.g. for addressing different companies) Different models with the same generation rule (write presentation rules only once inside a

single company)

no vendor lock-in: standard Java Web applications can be easily maintained without the tool

WebML, the DSL for the Web

Horizontal vs Vertical DSLs

Vertical DSL: a language targeting the problem domain and usually a specific market, industry or field

Examples are configuration languages for home automation systems, modelling languages for biological experiments, analysis languages for financial applications and so on…

Horizontal DSL: a language targeting the solution (technology) domain and hence with a broader application field.

Examples are SQL, Flex, Pixel bender, and so on...

WebML

a “horizontal” DSL, targeting the Web domain

standardization proposal started within the OMG

Business Agility: keep your IT applications always aligned to Business needs

Development Speed: boost up your development productivity, up to 3 times (FP metrics measured, productivity index > 110 FP/staff month)

Reuse: build up a fertile environment, with your own custom components

Your visual identity

The connections to your information systems

Your custom business logic

You are the homeowner: generated applications are compliant with Java standards

No proprietary runtime servers

No additional runtime costs
