BSCIT - SEMESTER - 4 - SUMMER - 2015

PROGRAM  - BSC IT
SEMESTER  4
SUBJECT CODE & NAME - BT0081 - Software Engineering


1.  Explain different kinds of software applications.

Software  applications  can  be  neatly  compartmentalized  into  different categories.

System  software:  System  software  is  a  collection  of  programs  written  to service  other  programs.  Some  system  software  processes  complex information  structures.  Other  systems  applications  process  largely indeterminate data. It is characterized  by heavy  interaction with hardware, heavy  usage  by  multiple  users,  concurrent  operation  that  requires scheduling,  resource  sharing,  and  sophisticated  process  management, complex data structures and multiple external interfaces.

2.  What are the Limitations of waterfall model? Explain in brief.

Limitation of the waterfall model

1.  The linear sequential model or waterfall model assumes the requirement of  a  system  which  can  be  frozen  (baseline)  before  the  design  begins. This  is  possible for systems  designed to  automate  an  existing  manual system. But for a new system, determining the requirements is difficult as  the  user  does  not  even  know  the  requirements.  Hence,  having unchanging requirements is unrealistic for such projects.

2.  Freezing  the  requirements  usually  requires  choosing  the  hardware (because  it  forms  a  part  of  the  requirement  specifications)  A  large project might take a few years to complete. If the hardware is

3.  Describe the operation of Data flow model with the help of a block diagram.

Data-flow models

Data-flow model is a way of showing how data is processed by a system. At the analysis level, they should be used to model the  way in which data is processed  in  the  existing  system.  The  notations  used  in  these  models represents functional processing, data stores and data movements between
functions.

Data-flow models are used to show how data flows through a sequence of processing steps. The data is transformed at each step before moving on to the  next  stage.  These  processing  steps  or  transformations  are  program functions when data-flow diagrams are used to document a software

4.  Explain  the  various  activities  involved  in  Software Reengineering process model.

Software Reengineering Process Model

Reengineering  takes  time;  it  costs  significant  amounts  of  money;  and  it absorbs  resources  that  might  be  otherwise  occupied  on  immediate concerns. For all of this reason, reengineering is not accomplished in a few months  or  even  a  few  years.  Reengineering  of  information  systems  is  an
activity  that  will  absorb  information  technology  resources  for  many  years. That‟s  why  every  organization  needs  a  practical  strategy  for  software reengineering.

5.  Explain Black-Box Testing in detail.

Black-Box Testing

Black-box testing, also called behavioral testing, focuses on the functional requirements of the software. That is, black-box testing enables the software engineer  to  derive  sets  of  input  conditions  that  will  fully  exercise  all functional requirements for a program. Black-box testing is not an alternative to  white-box  techniques.  Rather,  it  is  a  complementary  approach  that  is likely to uncover a different class of errors than white-box methods.

6.  With the help of bock diagram explain how global problem solving can apply a software-driven approach to enhance the efficiency of problem solving.


A View of Problem Solving and Software Engineering

As we know a  view  of  problem  solving  utilizing  software technology and the impact of global problem-solving strategies on softwaredriven  problem-solving  strategies.  They  illustrated  how  global  problem solving can apply a software-driven approach to enhance the efficiency of problem  solving.  The  effectiveness  of  these  approaches  on  business performance  in  terms  of  the  business  value  created  and  software  project optimization  achieved  was  projected.  Business  value  and  project
