Hello Ranchers,

Finally the wait is over.

It gives me mammoth pleasure to inform you that I have cleared SCEA/OCMJEA exam with the score of 139/160.

I'd like to take this opportunity to thank everyone in this forum who helped me to pass SCEA/OCMJEA exam. It’s been a long waiting after submitting my assignment, finally I got what I wanted.

I enjoyed exam preparation a lot during part1 and 2, part 3 is just the straight hit.

I am in the process of implementing component diagram, to start with two approaches are in my mind.

Both are Mark Cade and Humphrey Sheil implementations by grouping tiers..

1. Defining components use case specific.
2. Defining components business specific like admin actions are in one component segment, user actions are in one component segment

Please advice.
I was reviewing Mark Cade and Humphrey Sheil Part II, noticed that sequence diagrams didn’t meet the assignment requirement. As per the use case all public methods must be used in sequence diagram.

Class diagram is high level didn’t touch several implementation areas like DAO and Service call segments.

Final one is Component diagram is more generic, is this approach recommended to implement?
Sadanand,
I was hard time understanding in uml specifications like Interfaces exposed with lollipops. The tools which I am using (Star UML, Rational Modeler and IBM Rational Architect) doesn’t have a feature of lillipops.
Do they really concern about that. Please find below url and share your thoughts.

Sadanand, I have a question related to UML specifications.

I am using IBM Rational Software and IBM Rational Software Architect tools none of them were UML 2.4 compliant, assignment is specific about the UML 2.0+
