Smart development with a pragmatic MDA approach

1 of 33
MDA: Smarter development of Java EE applications ,[object Object],<logo>
Agenda ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Speakers Background ,[object Object],[object Object],[object Object],<logo> ,[object Object],[object Object],[object Object]
Model Driven Architecture ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
MDA Process ,[object Object],[object Object],[object Object],PIM Working software PSM CIM Transformation
MDA Process ,[object Object],[object Object],[object Object],PIM Working software PSM CIM Transformation
Top-down vs Bottom-up Working software Models PIM PSM Top-down Bottom-up Transformation Skilled Transformation Capture domain information Transformation Capture technical information Simple tools (whiteboards) Modify code As needed
Pragmatic approach to MDA ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Models Code
Bottom Up : Target Architecture ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Patterns Platform indep. model Target architecture Domain model
Bottom Up : Target Architecture ,[object Object],[object Object],Platform specific model Transformation Platform indep. model Target architecture Domain model
Bottom Up : Domain Model Concepts ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Platform indep. model Target architecture Domain model
MDA Toolchain : Pick your tools! ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Ingredients for pragmatic MDA A well-defined Technology Stack A well-defined Target Architecture A well-defined Automation Scope ,[object Object],[object Object],Code Patterns Meta model Models Templates
Ingredient 1: Technology-stack
Ingredient 2: Target-architecture
Ingredient 3: Automation-goals Stereotype Generator Artifacts
Basic Principles Application Aspect Target Architecture Translation Stereotype Template Engine Approach Artifacts Translation 1 1..n
Basic Principles: by example Entities Application Aspect Template Engine POJO + ORM Target Architecture Translation Entity Class JPA Config DAO Class Artifacts <<DomainEntity>> Stereotype Translation DDD (Eric Evans) Approach
By Example Conference Administration as a Service (CAaaS) WS1 Registration Service Schedule Service WS2 Domain Model RIA (Silverlight) Access Logic Data Persistency Client Domain Facades Business Facades
By Example Domain Model
By Example Domain Facade
By Example Domain Logic
By Example Web Service Fine-tuning with “Tagged Values” in EA Facades use a canonical data model (CDM) to allow XSD-based data contracts
Stereotypes with a background ,[object Object]
Room for hand-crafting! Seam injection is used to merge “custom code” Seam component (separate class) holds “custom code”
From meta-model to code Step 1  Build your meta-model Create your meta-model in EA using predefined meta-types and object-orientation Properties in your meta-model become tagged-values in your model
From meta-model to code Step 2  Save your meta-model as UML 2.0 Profile Export meta-model as UML 2.0 Profile Import UML 2.0 Profile into your model Ready to model!
From meta-model to code Step 3  Take your pick and model... Your own stereotypes in EA Drag-and-Drop from toolbox to diagram
From meta-model to code Step 4a  Generate artifacts (update/build process) The template engine transforms stereotypes into artifacts ,[object Object],[object Object],[object Object]
From meta-model to code Step 4b  Generate artifacts (template engine) Ant-task EA repository EA api FMPP Template Models (java class) Templates Templates Templates Templates DomainEnumeration.ftl
From meta-model to code Step 4c  Generate artifacts (output) Java Entity Java DAO C# Entity Hibernate mapping XSD Type
Are you ready for MDA? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
