How are modularity patterns and best practices different from pre Java 9 apps? or are the very similar or almost the same?
3 months ago
If some applications have lots tightly coupled dependencies within a core monolithic module, does migrating to Java 9 help break that module into smaller pieces through the modularization patterns and best practices mentioned in the book?

Does the book cover any dependency breaking technique in order to meet the necessary modifiability requirement?

and finally does the book cover the principles of package cohesion and packing coupling?

Do you think the TOGAF certification is worth pursuing then?

EA is more about information management stuff than purely technical stuff right?

Hi Sameer,

Does this book cover how to progress through the career path of as a software professional from a software application architect to software system architect then finally to an enterprise architect?

Does it explain the differences in between a software architect, system architect, IT architect(e.g. IBM likes to use ITA for their technical consultants), and enterprise architect? because software architect, and system architect are used interchangeably.

Does the book cover specific software technologies? or architectural patterns and tactics?

Does the book cover any software development methodology(e.g. agile/scrum, waterfall)? there have been lots of debates about if agile methodology is adopted that the role of an architect actually diminishes.

Does the book cover any specific EA framework or methodology(e.g. TOGAF)? because lots big consulting companies and companies with large IT organizations(e.g. banks) want their architects to have TOGAF experience and knowledge.

Got it, that is what i thought too because I was having difficulty digging up useful materials from the Oracle website.
I have confirmed it is provided on Safari Books Online as well, in the online version the "About the Download" has instruction for the test engine installation
Really depends on the size of your organization, is it making money/profit, your tenure with it, your contribution to it and if the boss is willing to assist in professional recognition
are there any additional reference or study materials from the Oracle website that are helpful in passing the exam(s) for JEE6?
Hi, I want to ask is the book technology agnostic? or does it cover or refer to some Oracle technology product(s) in the case studies or examples?
I want to ask if I already have OCMJEA5, is it worth upgrading the OCMJEA6? and whats the difference(s) between two editions? or is it worth to wait until JEE7?

A question for Paul Allen and Joseph Bambara: Does the book compare between JEE6 with the previous editions? and introduce the major new features of the latest edition?
Does the book also covers OO principles in theory from the design perspective and how do OO concepts relate to the principles?
Another question is does the author still think or feel that UML is still important for OOAD?
Includes relocation package? lets say from Taiwan or Hong Kong.

So if I just pass the 1Z1-807 exam then I will get the "Oracle Certified Master, Java EE 6 Enterprise Architect" certification(i.e. upgrade)?
