Management Information System (contd..)
MIS is an integrated man/machine system for providing
information to support operations, management and decision
making function in an organisation. This system utilises computer
hardware, software, manual procedures, management, decision
models and a database.

In a GDSS electronic meeting, each attendee has a workstation.
The workstations are networked and are connected to the facilitators
console, which serves as the facilitators workstation and control
panel, and to the meetings file server.
All data that the attendees forward from their workstations to the
group are collected and saved on the file server.
The facilitator is able to project computer images onto the projection
screen at the front of the room.

Trends in Information Technology
Grid Computing:
Involves connecting geographically remote computers into
a single network capable of working in parallel on
business problems that require short-term access to large
computational capacity
Rather than purchase huge mainframes or super
computers, firms can chain together thousands of smaller
desktop clients into a single computing grid.
Saves infrastructure spending, increases speed of
computing, and increases the agility of firms.
What is Virtualisation, Green Computing?
On-Demand (Utility) Computing
-
7/28/2019 MIS - FMS SSM
96/99
( y) p g
Firms off-loading peak demand for computing power to remote,
large-scale data processing centers
Developed by IBM, SUN, and HP
Firms pay only for the computing power they use, as with an
electrical utility.
Excellent for firms with spiked demand curves caused by
seasonal variations in consumer demand, e.g. holiday shopping
Saves firms from purchasing excessive levels of infrastructure
What is Software As A Service (SAAS)?
Autonomic Computing
-
7/28/2019 MIS - FMS SSM
97/99
Autonomic Computing
Computer systems (both hardware and software) have become
so complex that the cost of managing them has risen.
Thirty to fifty percent of a companys IT budget is spent
preventing or recovering from system crashes.
Operator error is the most common cause of crashes.
Autonomic computing is an industry-wide effort to develop
systems that can:
Configure, optimize, and tune themselves
Heal themselves when broken
Protect themselves from outside intruders and self-
destruction
Edge Computing
-
7/28/2019 MIS - FMS SSM
98/99
g p g
A multitier, load-balancing scheme for Web-based applications.
Processing load is distributed closer to the user and handled by
lower-cost servers.
Lowers cost of hardware
Increases service levels
Provides firm greater flexibility in responding to service requests
Seasonal spikes in demand can be off-loaded to other edge
servers.
Service-Oriented Architecture
-
7/28/2019 MIS - FMS SSM
99/99
Service Oriented Architecture
SOA refers to the use of Web services in a firm to achieve
integration among disparate applications and platforms.
A firm might have applications (payroll) running on older AS400
IBM machines, IBM mainframes (customer data and inventory)
and newer applications running on client/server networks.
In SOA, these applications are integrated so that information
stored on various systems can be brought together and fed into
newer applications running on more contemporary equipment.
SOA is generally less expensive than rebuilding all the older
applications and adopting a new enterprise wide system.
