Software Engineering Research in SITE- University of Ottawa Software Engineering Research in SITE- University of Ottawa Presentation Transcript

  • Graduate Studies in Software Engineering
    • Solving customers problems by the disciplined development of large applications
      • Applying engineering methods to software
    • Some areas of SE knowledge and research
    • Software defects cost upwards of $60 Billion per year
    • Productivity of developers and management teams ranges dramatically
    • How can we improve software engineering in order to cut the cost to society of poor quality and excessive development ?
    What is Software Engineering? – Quality (performance, usability, security, etc.) – Education – Evolution and maintenance – Modeling – Tools – Project management – Testing – Design – Process – Requirements
  • Using Collaborations and their Composition for Requirements Modeling in Distributed Systems
    • Gregor Bochmann
    • Objectives
      • Compose collaborations according to rules of sequential or concurrent execution
      • Derive protocols to implement the requirements
    • Research questions:
      • Under which conditions can two collaborations be combined?
      • How can contradictions be reconciled?
      • How can you build tools to derive designs from requirements?
  • Supporting Use Case based Requirements Engineering
    • St éphane Somé
      • With Daniel Amyot, Gregor Bochmann and Amy Felty
      • 5 students
    • Objective:
      • Create an environment for use case capture, analysis and validation
    • Research questions:
      • Can use cases be formalized while remaining user-oriented?
      • Can we automate behaviour synthesis from use cases?
      • Can we automate validation against use cases?
    • Results:
      • Open source tool at http: //sourceforge . net/projects/uced/
      • A UML metamodel for use case description
      • A Restricted natural language for use cases
      • Algorithms for state model synthesis from use cases
      • Algorithms for test scenario derivation
  • Evolving E-Health Business Processes Around Accessible Data Warehouses
    • Daniel Amyot
      • With Liam Peyton, Michael Weiss (Carleton), Greg Richards (Management), Alan Forster (Medicine)
      • 8 students
    • Objective:
      • Integrate performance management and business process automation, in a model-driven manner
    • Results:
      • A test framework and sample scenarios for E-Health processes
      • A process and data simulation environment for Ottawa Hospital
      • A framework for compliance of business processes to legislation
      • Combined Key Performance Indicators with process models
  • User Requirements Notation (URN): Modelling, Analysis and Transformations
    • Daniel Amyot
      • With Gregor Bochmann, St éphane Somé
      • 3 profs from Carleton, and 4 students
    • Objective:
      • Integrate scenarios and goals to improve requirements modelling and analysis (URN = UCM + GRL)
    • Results:
      • Scenario analysis and goal analysis algorithms
      • Open source, Eclipse-based tool support ( jUCMNav )
      • Transformations from UCMs (Use Case Maps) to other formalisms
      • Prototype for aspect-oriented UCM and GRL
      • Integration of URN with a commercial requirements tool
      • Applications to business process modelling, requirements engineering, pattern formalization, and performance analysis
  • Formal Aspects of Software Testing
    • Guy-Vincent Jourdan
      • With Hasan Ural
    • Objective:
      • Extend the foundations of testing and other formal techniques to provide assurance that software systems work as expected
    • Research questions:
      • How can we prove the "equivalence" between a model and an implementation with a test sequence that is as short as possible?
      • How can we significantly reduce the number of tests in a test suite, without significantly reduce its coverage?
      • How to can we do adaptive testing , with test sequences chosen on the fly based on observed results?
  • Software Correctness and Safety
    • Amy Felty
      • With Stan Matwin and Luigi Logrippo (UQO)
      • 5 students
    • Objective:
      • Provide assurance that complex software systems work correctly and safely , by studying the application of theorem proving and other related formal techniques
    • Sample Result:
      • Recently developed an approach to detect a large class of unwanted conflicts among features in telecommunications and other large software systems
  • Privacy-Compliance in B2B Networks
    • Liam Peyton
      • With Abed El Saddik, Carlisle Adams and Bernard Stepien (Researcher)
      • 3 students
    • Objective:
      • To manage privacy compliance while enabling distributed data sharing and data mining
    • Results:
      • Identified gaps in existing technology standards (P3P, EPAL, Liberty Alliance)
      • Proposed audit trail service (Information Transfer Registry)
      • Service Oriented Architecture framework for data sharing in on-line collaboration environments
  • Complexity Reduction in Software Engineering (CRuiSE)
    • Tim Lethbridge
      • 2 students
    • Objective:
      • Enable software engineers to develop more easily
    • Research questions:
      • What are the sources of complexity in the SE process , and how can we reduce them
      • How can we bridge the gap between programming and modeling
      • What are the obstacles to a model-centric approach ?
      • Why do many industrial software engineers still consider writing code to be their central activity?
      • How can modeling languages and tools be made more usable ?
  • Improving Software Engineering Education
    • Tim Lethbridge
    • Objective
      • Improve the quality of the software engineering workforce through education
    • Research questions:
      • What are the areas of software engineering where education is most lacking ?
      • How do we structure curricula and certification tests so software engineers can produce better software?
