3. WHAT IS MODELING ? Models is an important software engineering tool that helps us in understanding and analyzing a complex problem. Modeling a software system involves identifying its structural and behavioral characteristics.

4.  RAM (Reusable aspect models)  UML (unified modeling language)  Umple (code generation is possible)  AspectSM (test case generation)  VCL (Visual contract language)

5. Figure 1: Paradigms and semantics of modeling approaches [1]

6.  Scalability and consistency.  Integration of Class, Sequence and State diagrams into one coherent approach.  Packages Aspect Models for easy and flexible reuse.  Performs consistency checks.  Defines weaving algorithm.  RAM.

7. Figure 2: Merging Class Diagrams with Kompose [2] Figure 3: Sequence Diagram Weaving Example [2]

8.  Structural view  State view  Message view

9.  Aspect Oriented Multi-view modeling approach.  Describes both structure and behavior of a software design concern.  Allow designers to apply reusable design concerns within the design model of the software under development.  RAM weaver can create woven views of a composed model for debugging, simulation or code generation purpose.  During the weaving process consistency checks are performed.

10.  UML is used to represent object oriented applications. It’s standard meta model does not support aspect oriented applications.  RAM uses UML and extends UML’s meta-model to represent aspect-oriented applications.  Some techniques based on RAM supports reusability.

11. Design Model Interfaces  Customization interface  Usage interface  Variation interface Design Model Hierarchies  Model extensions  Model customizations

14.  When subject’s state changes, all observers are notified by calling an Update operation.  Push  Pull  Extended design of observer pattern is MVC( Model View Controller ).

17.  Completeness  Size  Vertical Design Decomposition  Horizontal Design Decomposition

18. Figure 8:TouchRAM in Use [5]

19.  Multitouch-enabled tool for agile software design modeling based on RAM approach.  Aims at reusability and scalability.  Comes with reusable design concern model library (RDCML)  Ease of use, reuse and agility.

20.  Need for Design Models  Should encourage concern driven modeling  Promote usage of RDCML Future Scope:  Gesture control within Touch RAM  Specifying features and impacts within Touch RAM  Code Generation Capabilities
