Question No:( Marks: 2 )

Describe the component of DSS architecture

Question No: ( Marks: 2 )
Write any example for Iterative and Incremental model. One example for each.
Iterative model
For example clients may not be aware of exactly what requirements they want before
they see a
working prototype and can comment upon it - they may change their requirements
constantly,
and program designers. This is an example of iterative model
Incremental model
Example -An example of this incremental approach is observed in the development of
word
processing applications where the following services are provided on subsequent
modules:
• Basic file management, editing and document production functions
• Advanced editing and document production functions
• Spell and grammar checking
Question No:
Identify different phases of Spiral model.
There are different phases uses in spiral model for example organization focusing on
Determine the objectives, find the alternatives, plan next phase and develop the next
level product. Evaluate alternatives, identify and resolve risks – This involves. Risk
analysis and Prototyping, develop, verify next-level product Plan next phase and to
determine the strength and weakness in organization
Identify the various phases of decision making process? (3)

Design: Once the debtors have been analyzed on the basis of pattern of collection,
options can be
generated to improve collection rates.
Choice: Now a selection has to be made which single strategy or combination of
strategies
should be implemented.
Implementation: Now the stage comes of communicating the policy approved to the
interested
and Relevant
Monitoring: Once the decision has been implemented, the effects and responses should
be
Monitored
Question No: ( Marks: 3 )
List any three benefits of CRM.
Benefits of CRM:
• Maintains and enhances customer base
• Encourages customer loyalty
• Gaining more customers’ wallet-share
Question No: ( Marks: 5 )

why prototype is used? Also explain its advantages.
Question No: ( Marks: 5 )

discuss the second phase of spiral model along with the steps it involved

Some new features in HTML5

A new article has been posted on eTechy101.com.
The post title is 'HTML5: Latest Features'. Below is a preview of the post.

There are some very user-friendly and efficient features that have been added to
HTML5 and which have made HTML5 far more powerful and efficient as compared to
the previous versions. Some of the differences are presented:

Consider a code in HTML4:

<img src="path/to/image"

alt="About image" />
<p>Image of Mars. </p>

In the above code, there unfortunately isn’t any easy or semantic way to
associate the caption, wrapped in a paragraph tag, with the image element
itself. HTML5 rectifies this, with the introduction of the <figure>
element. When combined with the <figcaption> element, we can now
semantically associate captions with their image counterparts. A better
alternative is presented in HTML5:

What are simple events and what are compound events?                       [3Marks]

1. For a particular data of 5 pair of values:                              [3 Marks]

      The fitted regression line is:

Y= - 0.5 + 0.5 x

Find the standard error of estimate (Sy.x); what doest it indicates?

This is question already given to us in our 2^nd Assignment. Only the regression line values were change. Rest of values were same.

Be careful I am giving the assignment solution not the asked question.
