For companies, Information systems are used to
make decisions, operate, and plan. For schools, many on-line universities offer
diplomas for DSS, MIS, and EIS disciplines, but they are not offered in other major
schools. Today, companies and schools are turning to computer systems for
everyday business. These computer systems speed up the methodology of doing
business. EIS, MIS, and DSS are different computer systems that do different
operations.
EIS, which stands
for Executive Information System, is the most specialized system. This program
is primarily used for most difficult to use for decision-making. The decision-making compares, analyzes, and
highlights variables to select the best one. This kind of storage works best
with high data storage; the other parts can be cheap. According to Floyd Kelly,
a researcher on EIS, more senior administrators use this program for they have "limited time, limited keyboarding
skills, and little direct experience with computers” [1]. Therefore, the software contains more text,
database, graphic base, and model base than MIS.
MIS, which stands
for Management Information System, is a supportive computer system. This program is medium difficulty. The
decisions are used to communicate, plan, and summarize variables. Unlike EIS, employees
of a company can benefit from this program. They use internal data and micro-job
functioning for their job. Back in retail, my manager had developed a retail
management information system. The
system benefitted by increasing profits through the tracking of procurement,
inventory, and sales [2].
DSS, which stands
for Decision Support System, is a general system. The system is the easiest to
use for decision-making. This program is
useful in taking raw data and documents to create different combinations; the
knowledge is useful in making decisions. Managers use the information most. They use data to calculate inventory, sales,
and revenue. An example of a company using DSS is Sam’s Bookstore. Through the use
of DSS, a table was created with quantities and demands. Past purchases and future demands were
estimated. The results showed the maximum profit was as $12,250 at ordering 2000
quantity of books. Sam’s Bookstore has
an easier time in their decision-making with the help of DSS. [3]
The three systems
are similar because they all work together. MIS stores small files, such as
documentation and texts, which is used by EIS and DSS. DSS and EIS are used for
critical decision-making. Middle to higher level management use MIS, while DSS
is for all levels of the corporation. EIS is the most advanced program.
In conclusion, EIS,
MIS, and DSS are computer systems where each program is designed for a
different skill of the user. More on-line schools are based on information
systems, and many more companies are using them today. Both on-line learning
and information companies are growing each year. Will accredited schools be
replaced by on-line learning? Unlikely, but as more companies continue to rely
on computer systems, the demand for skilled computer users continue to grow. Computers
are the future, I hope my kids will be able to experience a similar, if not,
better one than mine.
