This tutorial focuses on the Domain-specific Language (DSL) called IFML, which has been adopted as a standard by OMG in March 2013. The Interaction Flow Modeling Language (IFML) is designed for expressing content, user interaction and control behaviour of the front-end of software applications, as well as the binding to the persistence and business logic layers. IFML is the missing piece for modeling the front end of software applications and perfectly complements other modeling dimensions in broad system modeling projects. Therefore, IFML works best when integrated with other modeling languages in the MDA suite, such as UML and BPMN. This tutorial illustrates the basic concepts of IFML, presents the design best practices and integration with other modelling languages, and discusses some industrial experiences (also featuring quantitative measures of productivity) achieved by the companion tool WebRatio. At the end of the tutorial, attendees will get a general knowledge about IFML (they will be able to design simple models and to derive models from existing interfaces), will be able to associate front-end design with system modelling at large, will see the associated MDE tool WebRatio at work, and will get a glimpse of real-life industrial applications developed for large enterprises. This will let them appreciate the advantages of a model-driven development approach at work within large-scale industrial project.

The tutorial will be aimed at both industrial and academic attendees, including Ph.D. students. Prerequisite for attending the tutorial is a general knowledge about the bases of model-driven development, software engineering, and some general purpose modelling languages like UML.

Transcript

  • 1. IFML: Building the front end of Web and Mobile applications with OMG’s Interaction Flow Modeling Language Marco Brambilla marco.brambilla@polimi.it @marcobrambi
  • 2. The modeling approach
  • 3. What is a model? Models Mapping Feature A model is based on an original (=system) Reduction Feature A model only reflects a (relevant) selection of the original‘s properties Pragmatic Feature A model needs to be usable in place of an original with respect to some purpose ModelrepresentsSystem Purposes: • descriptive purposes • prescriptive purposes
  • 4. CIM, PIM, PSM Modeling Levels Computation independent (CIM): describe requirements and needs at a very abstract level, without any reference to implementation aspects Platform independent (PIM): define the behavior of the systems in terms of stored data and performed algorithms, without any technical or technological details Platform-specific (PSM): define all the technological aspects in detail
  • 5. Modeling levels - CIM Eg., business process
  • 6. Modeling levels - PIM Eg., business object description and constraints
  • 7. Modeling levels - PSM How the functionality in the PIM is realized on a certain platform Using a UML-Profile for the selected platform, e.g., EJB
  • 8. The UI Modeling Problem
  • 9. User interface and interaction development is a painful phase of software process … for everybody! … not only for the Web! UI Modeling Problem
  • 10. Costly and Inefficient process Complexity of user interfaces (UIs) Ineffective tools Manual development No MDE technology The UI Design Problem
  • 11. No model driven engineering Platform independent description of UIs Focused on user interactions No definition of graphics and styles Reference external models The UI Design solution: IFML
  • 12. User interaction has been overlooked in software engineering standards Hence the Interaction Flow Modeling Language (IFML) Standardization gap
  • 13. 13 We were going to make them an offer they couldn’t refuse. In less than 2 years (a record in OMG!), we obtained approval of the IFML standard The Object Management Group
  • 14. User interaction has been overlooked in software engineering standards Hence the Interaction Flow Modeling Language (IFML) In less than 2 years (a record in OMG!), we obtained approval of the beta IFML standard Version 1.0 due to come out in these weeks Standardization gap
  • 15. The Interaction Flow Modeling Language
  • 16. IFML Objectives Binding to Persistence Layer Navigation Path Binding to Business Logic Content Event
  • 17. IFML Objectives: Content Content
  • 18. IFML Objectives: Navigation Path
  • 19. IFML Objectives: Navigation Path
  • 20. IFML Objectives: Events Mouse Over
  • 21. IFML Objectives: Events
  • 22. IFML Objectives: Binding to business logic
  • 23. IFML Objectives: Binding to business logic
  • 24. IFML Objectives: Binding to persistence Content Book Title: string Cover: file List Price: currency Price: currency Save: currency Rating: integer ………
  • 25. IFML Overview - Extensibility
  • 26. IFML Essentials
  • 27. Multiple views for the same application Mobile and multi-device applications Visualization and input of data, and production of events Components independent of concrete widgets and presentation Interaction flow, initiated by the user or by external events User context: the user status in the current instant of the interaction (position, history, machine, platform,…) Modularization of the model (design-time containers for reuse purpose) User input validation and constraints, according to OCL or other existing constraint languages Covered aspects
  • 28. IFML by example Basic navigation flow between ViewComponents
  • 29. IFML by example Basic navigation flow between ViewComponents Artists List Artists Artist Event View Component View Container ParameterBinding«ParameterBindingGroup» SelectedArtist  AnArtist
  • 30. IFML by example Album Search «Window» AlbumSearch Album List «Window» Albums Album Details «Window» Album «ParameterBindingGroup» Title  AlbumTitle Year  AlbumYear «ParameterBindingGroup» SelectedAlbum  AnAlbum «Form» «List» «Details»
  • 31. IFML by example Nesting of ViewContainers Tagged ViewContainers (XOR) Artist and Album List Albums&Artists Albums&Artists Artist Details Artist Album Details Album [XOR] Album or Artist «ParameterBindingGroup» SelectedAlbum  AnAlbum «ParameterBindingGroup» SelectedArtist  AnArtist Select Artist Select Album
  • 32. ViewComponentParts: • Data binding • Parameters Types of ViewComponents (<<List>>) IFML – adding details to ViewComponents «DataBinding» MailMessage «ConditionalExpression» self.mm2MailMessageGroup = MailBox «List» Message List «Parameter» MailBox : MailBox

  • 117. On the positive side: Almost 80% of the delivery effort concentrates in the phases of data design, hypertext design and prototyping: • more development time is spent with the application stakeholders MDD allows a more flexible distribution of responsibilities between the IT department and the business units The peak productivity rates has reached five times the number of delivered function points per staff-month of a traditional programming language like Java Comments
  • 118. On the negative side.. Acer estimates that it took from 4 to 6 months to have fully productive developers with MDD, IFML, and WebRatio Difficult to find skilled people ..but.. The initial investment in human capital required by MDD pays off in the mid term • MDD benefits testing, maintenance, and evolution (which account for over 60% of the total lifecycle cost) • reasoning on the system is far more effective at the conceptual level Comments (continued)
