Objectives n n n Model based System Development - through ”modeling with objects and services” 2 roles: 1) Tool developer (Software Factory) 2) Application developer, (user of Software Factory). n Object-oriented -> Componentbased -> Service oriented n Reuse n Learn techniques n n n MDA – Model driven architecture Meta Modeling and modelltransformation * SOA – Service oriented architecture Unified Modeling Language (UML 2. 0) – for architecture MDI – Model Driven Interoperability Telecom and Informatics 10
Change in course from 2010 n We will use a new Metamodel environment, Kermeta, on top of EMF, instead of only focusing on GMF. We will keep the sequence from 2010 and 2008 with a bottom up MDLE approach(rather than top down as we had in 2009) – with first learning the principles and technologies for MDE in February. We will also give a short introduction to the focus area of Service Innovation, Service Science and Service Engineering, before finalising the MDE part. . n In March we will focus on how to practice a model driven approach to Services (MOS), and in April we will introduce the topic of Semantic Web/services and Model Driven Interoperability (MDI) – before a final conclusion of the course Telecom and Informatics 11
New since last year n Initial focus on Eclipse with EMF and GMF and transformation tools n Use of Modelio commercial modeling tool – for UML 2 and BPMN 2. 0 (This is a new version of Objecteering) n New focus on “Service Science” – with Service Innovation (with BI/NHH), Service Design (OAH) and Service Engineering (UIO) n New standards: Focus on OMG MDA standards, and on Soa.

What is Enterprise Modelling? Enterprise Modelling (EM) is a capability for externalising, making and sharing enterprise knowledge. EM tools can either be: • used stand-alone to produce various kinds of model views, • integrated as front-ends to other systems, • part of an environment providing a contextual user-environment.

System and objects A system is a part of the real world which we choose to regard as a whole, separated from the rest of the world during some period of consideration. A whole that we choose to consider as a collection of objects, each object being characterized by attributes and by actions which may involve itself and other objects.

CRC Method, class, responsibilities, and collaborators n Method to learn the most basic OO concepts plus OO “thinking” n “The most effective way of teaching the idiomatic way of thinking with objects is to immerse the learner in the "object-ness" of the material. To do this we must remove as much familiar material as possible, expecting that details such as syntax and programming environment operation will be picked up quickly enough once the fundamentals have been thoroughly understood. ” n Technique also very useful during informal and creative analysis and design n Created by Kent Beck and Ward Cunningham, Textronix, 1989 Telecom and Informatics 54
The CRC-Card an object of paper personalizing the object Class (Name): Responsibility: Collaborators: Telecom and Informatics 55
Class, responsibilities, and collaborators n Class The class name of an object creates a vocabulary for discussing a design. Indeed, many people have remarked that object design has more in common with language design than with procedural program design. We urge learners (and spend considerable time ourselves while designing) to find just the right set of words to describe our objects, a set that is internally consistent and evocative in the context of the larger design environment. n Responsibilities identify problems to be solved. The solutions will exist in many versions and refinements. A responsibility serves as a handle for discussing potential solutions. The responsibilities of an object are expressed by a handful of short verb phrases, each containing an active verb. The more that can be expressed by these phrases, the more powerful and concise the design. Again, searching for just the right words is a valuable use of time while designing. n Collaborators Objects which will send or be sent messages in the course of satisfying responsibilities. Collaboration is not necessarily a symmetric relation. For example in Smalltalk, View and Controller operate as near equals while Ordered. Collection offers a service with little regard or even awareness of its client. Telecom and Informatics 56

Service Science SSME: Service Science, Management & Engineering Service systems are value cocreation configurations of people, technology, internal and external service systems connected by value propositions, and shared information (such as language, laws, measures, models, etc. ).

Service Oriented Architecture (SOA) definition n A set of components which can be invoked, and whose interface descriptions can be published and discovered (W 3 C). n The policies, practices, frameworks that enable application functionality to be provided and consumed as sets of services published at a granularity relevant to the service consumer. Services can be invoked, published and discovered, and are abstracted away from the implementation using a single, standards-based form of interface.
