SYSTEM CONFIGURATION

First State Bank provides full banking services to its customers through

a. automatic teller machines.

b. checking and saving accounts.

c. certificates of deposit.

d. loans.

e. electronic payroll.

f. electronic payment of customers’ bills.

The bank has eleven branch offices that cover a 30-mile radius. The main

office maintains a mainframe computer that serves the branch offices.

The competitive nature of the banking industry requires that customer

satisfaction be considered. Customers want prompt and accurate

servicing of transactions. Thus, accuracy and speed are crucial to the

success of First State Bank. How would you suggest the databases and

data communications facilities be configured for First State Bank?

KONFIGURASI SISTEM

Sebuah Bank Nasional menyediakan layanan full banking kepada

nasabahnya melalui :

a. Layanan ATM

b. Pemeriksaan tabungan

c. Sertifikat deposito

d. Pinjaman

e. Pembayaran gaji secara elektronik

f. Pembayaran tagihan nasabah secara online

Bank tersebut mempunyai sebelas kantor cabang yang mampu

menangani wilayah seluas 30 mile. Kantor pusat mengelola komputer

utama (mainframe computer) yang mampu melayani seluruh kantor

cabang tersebut. Persaingan bisnis dari industri perbankan membutuhkan

kepuasan nasabah yang harus diperhatikan. Nasabah ingin layanan

transaksi yang cepat dan akurat. Oleh sebab itulah akurasi dan

kecepatan menjadi hal yang krusial dalam meraih sukses dari Bank

tersebut. Bagaimana anda memberikan saran atas database dan fasilitas

komuniasi data yang akan dipasang di Bank tersebut?

Jawaban :

This configuration will entail a hybrid of centralized and decentralized

processing. Because customers should be able to bank at any of the 11

branches, cash withdrawal transactions from each branch should be

centrally processed and the customer databases updated. Deposits of

cash and checks and payment of customers’ bills can be stored on

remote computers, with the data being sent to the mainframe

periodically. Banks tend to be more concerned with the promptness in

recording cash withdrawals than cash receipts. Thus, the data

representing the payment of customers’ bills may be sent to the

mainframe computer four to six times a day for updating, while deposits

of cash may be transmitted only twice a day. The payroll accounts can be

stored and processed on the remote computers because these accounts

do not have ATM cards. Further, the mainframe at the main office can

process more efficiently if a front-end processor is used to relieve the

mainframe of data communication processes. A common-carrier network

is probably a good communication medium, but the data should be

encrypted. The individual teller terminals should be connected to the

remote main computer via dumb terminals. The tellers should not have

any reason to download data regarding customer account
