Q1. Explain DFD & Data
Dictionary? Explain in detail how the information requirement is determined for
an organization?
Answer. DFD
Data flow
diagrams represent the logical flow of data within the system. DFD do not
explain how the processes convert the input data into output. They do not
explain how the processing takes place.
A number of
guidelines should be used in constructing DFD.
• Choose
meaningful names for the symbols on the diagram.
• Number the
processes consistently. The numbers do not imply the sequence.
Q2. What is MIS? Define the
characteristics of MIS? What are the basic Functions of MIS? Give some
Disadvantage of MIS?
Answer. The industrial revolution has slowly
replaced man power with machines. There emerged the use of computer for data
processing. The digital computer was mainly designed to handle scientific
calculations. During 1940 to 1960 computers were used commercially for census
and payroll work which involved large amount of data processing. Since then the
commercial application exceeded the scientific applications.
Computer
Based Information systems are of vital importance in modern organization.
Systems professionals analyze, design, develop, implement and manage
state-of-the-art telecommunications, multi-media and other computer-based
information systems.
Q3. Explain Knowledge based system?

Q4. What are Value Chain Analysis

Answer. Product Differentiation and
Value Chain
Product
differentiation is the degree to which buyers perceive products from
alternative suppliers to be different. It is expressed by economic theory, the
degree to which buyers perceive imperfections in product substitutability. The
buyers of differentiated products may have to pay a price when satisfying their
preference for something special, in return for greater added-value. The
connection between the producer and buyers may be reinforced, at least to the
level of customer loyalty, and perhaps to the point of establishing a
partnership between them.
Q5. Distinguish between closed
decision making system & open decision making system? What is ‘what – if‘analysis?
Why is more time spend in problem analysis & problem definition as compared
to the time spends on decision analysis?
Answer. The decision-making systems can be classified in a number
of ways. There are two types of systems based on the manager’s knowledge about
the environment. If the manager operates in a known environment then it is a closed decision-making system. The
conditions of the closed decision-making system are:
a) The
manager has a known set of decision alternatives and knows their outcomes fully
in terms of value, if implemented.
Q6. What is ERP? Explain its
existence before and its future after? What are the advantages & Disadvantages
of ERP? What is Artificial Intelligence? How is it different from Neural
Networks?
Answer. Enterprise resource planning (ERP) is business management software that
allows an organization to use a system of integrated applications to manage the
business. ERP software integrates all facets of an operation, including product
planning, development, manufacturing processes, sales and marketing.
As a
researcher, we have done extensive studies on ERP in the Small and Medium
Enterprise (SME) space, including our latest benchmark report; ERP in SME 2011,
September, 2011. In that report, we
found that over 70% of manufacturing companies are already using some form
ERP. The majority of companies are using
it for managing finances and budgets.
But a large number also use it for planning and supply chain business
processes. In fact, even small users are
driving ERP further into their organizations.
