1. 7 Marks
   aWhat are various building block of the UML? State two-three lines for each.
   How to answer

   • Define UML building blocks: Things, Relationships, Diagrams
   • Things: structural, behavioral, grouping, annotational - 2-3 lines each
   • Relationships: dependency, association, generalization, realization
   • Diagrams: structural and behavioral diagrams overview
2. 7 Marks
   bCompare Object Oriented SDLC with traditional SDLC.
   How to answer

   • Define traditional SDLC phases
   • Define Object Oriented SDLC phases
   • Compare on basis: approach, modeling, reusability, iteration
   • Tabular comparison and conclusion
3. 7 Marks
   aWhen we focus on a S/W development on the basis of object orientation then which are the three basic models used?
   How to answer

   • State focus on object orientation in S/W development
   • List three basic models: object/class model, dynamic/state model, functional model
   • Brief purpose of each model
4. 7 Marks
   bDefine object diagram and class diagram. Also prepare class diagram for following object diagram.

   

   How to answer

   • Define object diagram: snapshot of instances and links
   • Define class diagram: classes, attributes, operations, associations
   • Differentiate class vs object level
   • Derive class Country with attribute Name and self-association Borders from given instances
5. 7 Marks
   aWhich model adds up mobility or occurrence of changes in class model? Explain with example of Data Communication.
   How to answer

   • Identify dynamic/state model as adding mobility/changes to class model
   • Explain states, events, transitions
   • Give Data Communication example e.g. connection/phone line states
   • Show state diagram with transitions
6. 7 Marks
   bCompare continuous life cycle state diagram with one-shot life cycle. State diagram.
   How to answer

   • Define continuous life cycle state diagram
   • Define one-shot life cycle state diagram
   • Compare on looping, final state, example objects
   • Draw both types schematically
7. 7 Marks
   aExplain activity diagram with help of "logging into an E-mail system".
   How to answer

   • Define activity diagram elements: activity, fork, join, decision, swimlane
   • Apply to logging into E-mail system steps
   • Show login flow with validation and error branch
   • Neat labeled activity diagram
8. 7 Marks
   bHow does sequence diagram differ from activity diagram? Draw a sequence diagram for a stock purchase that fails.
   How to answer

   • Differentiate sequence vs activity: time-ordered interactions vs control flow
   • List actors/objects for stock purchase that fails
   • Show lifelines, messages, alt/fail fragment
   • Neat sequence diagram with failure path
9. 7 Marks
   aIdentify at least 10 use cases for google chrome. Just list them textually and summarize the purpose of each use case in one or two sentences.
   How to answer

   • List 10 distinct Chrome use cases e.g. browse, bookmark, download, incognito, extensions
   • One-two sentence purpose for each
   • Cover user-centric functional scope
   • Textual list format
10. 7 Marks
    bConsider "spotify" application for e-music. Draw an use-case diagram which covers 10 use cases.
    How to answer

    • Identify actors: user, admin, payment gateway
    • List 10 Spotify use cases: play, search, playlist, subscribe etc.
    • Show include/extend and associations
    • Neat use-case diagram with system boundary
11. 7 Marks
    aWrite a short note on generalization. Explain all types of generalization done by UML 2.0.
    How to answer

    • Define generalization: is-a inheritance relationship
    • Explain UML 2.0 types: single, multiple, multilevel, hierarchical, hybrid
    • Notation with hollow triangle
    • Example class hierarchy
12. 7 Marks
    bWhat are different techniques used for coupling OO Programming Language with OODBMS?
    How to answer

    • Need to couple OOPL with OODBMS for persistence
    • Techniques: library extension, embedded OQL, persistent language extension, OODBMS binding
    • Explain each technique briefly
    • Examples of coupling
13. 7 Marks
    aWrite short note on programming style category "programming-in-the-large".
    How to answer

    • Define programming-in-the-large vs in-the-small
    • Features: modularity, versioning, team coordination, reuse
    • Role in large system development
    • Examples/tools
14. 7 Marks
    bWhat are various features of OOPL? Give names of five different OOPL other than Java and C++.
    How to answer

    • List OOPL features: encapsulation, inheritance, polymorphism, abstraction
    • Additional: extensibility, reusability, dynamic binding
    • Name five OOPLs other than Java and C++ e.g. Python, Smalltalk, Ruby, C#, Eiffel
    • One line for each language
15. 14 Marks
    Write short notes (on any three):

    1. i)DCOM
    2. ii)OOAD Methodologies
