Question No: 20 ( Marks: 3 )
What is the need for Accounting information system (AIS) to be linked
to all the information systems in an organization. ?
Solution:-Accounting information system is linked to all the information systems in an
organization. This is important because the data required for proper book keeping and

creditors, and managers) with information to make decision.
Question No: 21 ( Marks: 5 )
Discuss the attributes on which Organizational Information
Requirements depends
Solution:
There are several surveys indicate that a significant percentage of data warehouses fail tomeet business objectives or are outright failures. One of the reasons for this is
that requirement analysis is typically overlooked in real projects. Goal-
oriented approach to requirement analysis for data warehouses based on theTropos methodology. Two different perspectives are integrated for
requirement analysis: organizational modeling, centered on stakeholders, and
decisional modeling, focused on decision makers. Our approach can beemployed within both a demand-driven and a mixed supply/demand-driven
design framework.
Also Functional security requirements of information systems can roughly be classifiedinto two: computer security requirements and communications security requirements.Challenges for developing notations for expressing these requirements are numerous,
most importantly the difficulty of dealing with layers of abstraction, flexibility to adapt
into many types of requirements, groupings of requirements, and requirementdependencies. Many frameworks for dealing with information security highlight the
importance of a properly defined organization of security but fail to establish models to
support the specification. This paper establishes one such model and demonstrates how

the above difficulties can be overcome through extensive application of organizational
modeling of information security.
Question No: 22 ( Marks: 10 )
What are the management styles? Discuss in details.
Solution:-
Various management styles can be employed dependent on the culture of the business,the nature of the task, the nature of the workforce and the personality and skills of the
leaders..
There are three Management Styles.
Authoritative
Participative
Mixed
1)Authoritative
An Autocratic or authoritarian manager makes all the decisions, keeping the information
and decision making among the senior management. Objectives and tasks are set and the
workforce is expected to do exactly as required. The communication involved with thismethod is mainly downward, from the leader to the subordinate; critics such as Elton
Mayo have argued that this method can lead to a decrease in motivation from the
employee's point of view. The main advantage of this style is that the direction of thebusiness will remain constant, and the decisions will all be similar, this in turn can project
an image of a confident, well managed business. On the other hand, subordinates may
become highly dependent upon the leaders and supervision may be needed. AmandaGlass is the founder of this unique management style.
2) Participative
In a Democraticstyle, the manager allows the employees to take part in decision making,therefore everything is agreed by the majority. The communication is extensive in both
directions. This style can be particularly useful when complex decisions need to be made
that require a range of specialist skills: for example, when a new computerized systemneeds to be put in place and the upper management of the business is computer illiterate.
From the overall business's point of view, job satisfaction and quality of work willimprove. However, the decision-making process is severely slowed down, and the need
of a consensus may avoid taking the best decision for the business.
3) Mixed

decision is taken by the senior management keeping in view the views given by the
employee.
