Passed SCEA with 91%

I've been a silent observer of the SCEA forum and I have found the posts very useful. I got my results 4 weeks after submitting the assignment and taking part III:

Class Diagram (44 maximum) .......................... 36
Component Diagram (44 maximum) ...................... 43 Sequence/Colloboration Diagrams (12 maximum) ........ 12

A few comments:
- I have no idea why I lost so many points in the class diagram. I was actually quite satisfied with it, I thought I had applied the proper design patterns in the right spots. Anyways, the diagram contained roughly 60 classes/interfaces with only the methods that I considered relevant.
- The component diagram contained roughly 50-60 components. I've applied a logic similar to the one in the "official" Study Guide and put Views, Controllers, EJBs, DAOs
- Sequence diagrams took me an enoooormous time (for 12 points! *SIGH*).

Note (probably evident): don't even think about NOT using a UML tool for this. I've used "Poseidon for UML" that proved to be reasonably stable though it regularly required rebooting my laptop to get to the proper level of performance.

In terms of technical choices (EJBs, DAOs, WEB vs. Application), I think I've proposed reasonable solutions - at least the ones I'd have applied in the real life (I've been working with Java since 1995, poor old me). Again, no idea about why I got 36/44 on the class diagram, whether it was for my implementation choices or other things such as saying that the UC Log In didn't need details as I'd use JAAS to fulfil the requirements. Yes, my architect's feelings got hit here.

In terms of documentation, I've written what I felt was required to justify my choices - technical and "functional" - and the level of details I've applied to the various diagrams. I relied on the fact that the reader knew what Design Patterns were and when/how they should be used.

In terms of references for this work, there are a few "absolute must":
- "Gang of Four" Design Patterns
- Core J2EE Design Patterns
and a few recommended ones:
- Designing Enterprise Applications 2.0 (free on
- SCEA study guide

Finally, I'd say that working on this assignment took me 35-40 hours plus the time to "digest" the requirements (that I really - really! - suggest you read carefully).

Thank you all again!

And IMHO, this post would not have been off target in the SCEA forum...

Well, I did post it in the SCEA forum as well but then saw the message at the top saying "post your results here". I'm very disciplined, you know...
