Sistem Informasi
(IK 217)
Sistem Operasional (Transaction Porcessing Sistem)
Sistem yang dirancang untuk pemrosesan data sehari-hari di dalam dunia usaha
misalnya : Inventory Control, Billing ,dan lain-lain.
Sistem Informasi Manajemen (MIS)
Sistem yang dirancang untuk pemrosesan data yang menghasilkan informasi yang
berarti untuk pihak manajement, baik untuk level puncak , tengah, atau dasar.
Misalnya Laporan Rugi Laba.
Sistem Pendukung Keputusan (DSS)
keputusan berdasarkan kesimpulan atau perbandingan data dari sumber di dalam
atau diluar sistem yang ada .
Sistem Informasi Ekslusif (EIS)
Banyak keputusan yang harus diambil oleh manajemen dlm periodik dan perkiraan.
Untuk manghasilkan keputusan yang baik, maka perlu terlebih dahulu di definisikan
kebutuhan informasi yang akan digunakan dan dispesifikasikan tindakan alternatif
yang tepat. EIS dapat dibagi dalam dua kelompok :

EIS Terstruktur.
EIS ini adalah Informasi yang periodik dan diperkirakan, biasanya EIS untuk
kepentingan pihak manajemen yang di level tengah
EIS tidak Terstruktur
Tidak dapat diprediksi dan tidak periodik . Biasanya untuk pihak manajemen
puncak EIS biasanya juga dinamakan Executive Suport Sistem ( ESS )
Expert Sistem.

Sedangkan pendekatan modern dikemukakan oleh Steven Alter bahwa tipe sistem
informasi itu dibagi melalui pendekatan fungsi bisnis dalam organisasi, sbb:
1. Katagori Sistem Informasi yang berhubungan dengan area fungsi bisnis yang
spesifik/khusus (specific functional areas of business) adalah :
a. Product Design Systems / CAD Systems
b. Supply Chain Systems
d. Sales and Marketing Systems / Point of Sale (Pos), CRM
e. Finance Systems (checking account, credit cards, debit cards, smart cards,
electronic cash using in WWW’s payment)

keeping, and shipping.
A payroll system is a typical accounting TPS that processes transactions
such as employee time cards and changes in employee salaries and
deductions. It keeps track of money paid to employees, withholding tax, and
paychecks

system. Transaction processing systems are often so central to a business that TPS failure for
a few hours can lead to a firm’s demise and perhaps that of other firms linked to it.
Imagine what would happen to UPS if its package tracking system were not working!
What would the airlines do without their computerized reservation systems?

Three TPS supply summarized transaction data to the MIS reporting
system at the end of the time period. Managers gain access to the
organizational data through the MIS, which provides them with the
appropriate reports.

Unlike the other types of information systems, ESS are not designed
primarily to solve specific problems. Instead, ESS provide a generalized
computing and communications capacity that can be applied to a
changing array of problems. Although many DSS are designed to be
highly analytical, ESS tend to make less use of analytical models

The Interrelationship Among the Four Major Types Of Systems In Organizations
The various types of systems in the organization have interdependencies. TPS are major
producers of information that is required by the other systems, which, in turn, produce
information for other systems. These different types of systems have been loosely coupled in
most organizations.
