Umple s vision

Umple’s Vision


So what is umple

So what is Umple?

  • Model-oriented programming

  • Adds UML abstractions to any OO language

    • Class and state diagrams

  • Removes boilerplate code

  • Allows simultaneous textual and diagrammatic modeling

  • Eliminates round-tripping

    • Don’t edit generated code, just embed your custom code

Challenges and mitigation

Challenges and Mitigation


Remaining work

Remaining Work

  • Refine implementation of Nested and concurrent states

  • Build more examples

  • Complete the grounded theory study of Umple users

  • Model versioning and UML action language (next slide)


Model versionning and merging

Model Versionning and Merging

  • RSA: 712 – (~ 80 layout information) = 632.

  • Umple: About 35 lines of code (without layout information)


Uml action language

UML Action Language

  • Proposed ALs are textual

  • Umple’s action language is Java or Php.

  • Using a bottom up approach to achieve a better action language by:

    • Restricting existing OO language

      (limit access to internal representation of state machine)

    • Defining additional abstractions

      (event names)

    • Using language independent syntax

      (Boolean expressions)


Applying a research prototype tool in industrial practice

  • BACK UP SLIDES


Research questions

Research Questions

  • To what extent do software developers use state machines to model system behavior and specifications? What are the major factors behind that level of adoption?

  • Can the gap between state machine diagrams and code be minimized by incorporating core state machine abstractions in a high-level programming-like language?

  • To what extent could systems that do not use state machines abstractions be made to use them?


Hypotheses

Hypotheses

  • H 1: Software developers can develop software more effectively if they can develop state machines in a similar manner to which they develop code.

  • H 2: State machine adoption in the software industry can be enhanced if core state machine concepts are incorporated in programming-like textual language.

Model versioning and merging

Model Versioning and Merging

  • Existing tools use the XMI for persistence of models

  • XMI is relatively larger in size, high probability of conflicts

  • Software repositories do a good job with versioning and merging of code.

  • Umple syntax is highly concise and abstract
