why my question thread is locked?

I found that my question thread is locked, why?

Hi Guys,

Here are two questions about ABAP.

(1)

UML provides various diagram types. Mark the valid UML diagrams

(More than one answer is correct)

1 Aggregation

2 Composition

3 Class

4 Component

5 Behavior

I think the correct answers are (1) (2) (3). But the standard answers are (3)(4)(5).

Why?

(2)

Mark the valid logical nodes.

(More than one answer is correct)

1 Node

2 Table

3 Structure

4 Complex Data Object

5 File

The standard answers are (2) (3) (4). Can anybody explain it in details?

Thanks.

    Hi Micheal,

    The answer for the first question is:

    1)

    Firstly Aggregation & Composition are types of relationships and they are part of an UML Diagram used to connect the various classes/parts of that specific diagram.

    They are not the actual diagrams

    The remainig three options

    Class,

    Component &

    Behavioural are the UML Diagrams, which contain the various classes,components, packages etc.

    Hence the options 3,4,5 are correct.

    The UML Diagrams are categorized as

    Structural and Behavioural Diagrams.

    Under Structural Diagrams

    Class Diagram

    Object Diagram

    Component Diagram

    Deployment Diagram

    Under Behavioral Diagrams

    Use Case Diagram

    Sequence Diagram

    Collaboration Diagram

    Statechart Diagram

    Activity Diagram

    If you are still not clear then please go through the below link which clearly shows the various relations existing and about the UML Diagrams.

    Aggregation and composition describe the relation between different classes which can be shown using a class diagram. Component and behavious diagrams describe - as their names imply - the components and behaviours of the system, respectively.

      Thanks Uwe, you are right ! Reward all points to you.

      Got UML info as following:

      UML defines nine types of diagrams: class (package), object, use case, sequence, collaboration, statechart, activity, component, and deployment.
