Instruction to Candidates:

1.       Attempt any one question from each Section A, B, C & D.

2.       Section-E is Compulsory.

3.       Use of Non-programmable Scientific Calculator is allowed.

SECTION-A

1.       What is the main characteristics of  large software? How feasibility study is done for these projects?

2.       Which life cycle model would you follow for developing software products for each of the following applications?

(a) A well understood data processing applications.

(b) A new software product that would connect computers through satellite communication.

(c) Extremely large software connecting cellular services across the country.

(d) A new text editor.

Discuss advantages and disadvantages of each model in all case.

 SECTION-B

3.       (a) How decision trees and decision tables help in problem solving in designing? Explain by taking suitable example.

(b) Describe characteristics of information gathering tools.

4.       Draw Data Flow diagrams and describe data dictionary for the following problem. “The residents raise repair request of the different roads of the city. For each request, supervisor visits each road and studies the severity of the road condition. Depending upon the severity of the road condition and the type of the locality (VIP area, busy area, relatively deserted area etc.) he sets the priority of the repair work. He also estimates the requirements of the raw material of different types, types and numbers of machines, and type of numbers of the personnel required. He inputs this data to the software. Now based on this data, software schedules the repair of the road depending upon the priority of repair work and availability of the raw  material, machines and personnel. The mayor of the city can request for the various road repair statistics such as the number and type of repair carried out over a period of time and the repair work outstanding at any point of the time.”
