I would like to slightly repharce this quesion as, How can we handle indifference of opinion in the requirements?

Usually when we interact with the client as a representative of our organnization, one important this we need to follow is setting the right expectation even before we start gathering the requirements. When i say setting the right expectations, it means, making the client aware of your organizatations resource availability, technology areas, domain expertise, able to handle changes,etc.

And as the saying goes, "Talk to Resolve" most of the clients are open to discssion in the current industry trend, so sit and negotiate with your client and make him understand your organization capabilites.

The other way of resolving confilt is, implementing a strong change management process with in the software development life cycle.

104⟩ What is the main difference between portability and Platform independent?

I agree it is correct to say that Java is platform independent, but it is due to the Java Virtual Machine. Java programs are only intermediately compiled, which allows adaptation to the given environment it needs to run in later.

An example of a portability issue is the creation of Unix. The first version was not portable. It was specific only to that computer's architecture. Unix became portable when it was rewritten in C. The new version written in C was portable because C served as a "translator", if you will, between what underlying architecture or devices were physically in the computer and what unix wanted them to do.

106⟩ Explain in type2 dimension/flag current mapping there are three data flows i.e1. data flow for new rows2 .data flow for changed row3. data flow for updated changed rowwhats the difference between last two data flow?

When we are working with FLAG we can use only 2 filter transformations

also but at the initial stage it will be better to go with 3 filters. Where we

are using the FIRST Filter to insert the records for first

time, In second Filter we are inserting the records but these records are with

updated information and in third filter we are updating the records with

surrogate key. This third filter records will be updated with our changed

FLAG value 'ZERO'. Because we are identifying the current records with FLAG

values 'ONE'.
