The Smartcard Financial Settlement System

Introduction
For the Assignment for Database Programming and Administration you are
required to write a Financial Settlement System (FSS) for a Smartcard Transaction
Centre.
The Deliverables for the Assignment are structured in a way to enable you to
achieve a mark that is related to the amount of work that you will contribute and
the level of knowledge that you have attained. The detailed marking structure can
be found at the rear of the document.

Overview
For some time now there has been a trial deployment of a Smartcard System in
various locations throughout the country. A number of different types of Smartcard
terminals have been deployed at selected sites. The types of terminals include
Parking Meters, Payphones, various Vending machines and ticketing machines at
selected railway stations. A number of Smartcard enabled terminals have also
been placed in selected retail outlets like Newsagents and University canteens
enabling the holders of the Smart cards to pay for their purchases using these
cards.

The term electronic cash is often used when talking about Smartcard transactions;
however the electronic cash needs to be converted to real cash so that the
merchants, accepting the cards as payment, can be reimbursed. During the trial
phase, the merchants were reimbursed manually, once a week. The settlement
amount calculations have been done by the staff in our IT department and the
merchants were sent a cheque for the amount of the settlement. During the initial
trial phase the merchants were not charged a fee on the Smartcard transactions.

The Smartcard System is moving into the next phase of deployment. The number
of merchants will be increased and there is a requirement to automate the
Settlement process. The payment to the Merchants will be done via a direct credit
into their nominated bank accounts and is to be done daily.

Each month the merchants will be charged a fee for the use of the Smartcard. The
fee to be charged will be a percentage of the total transactions for the month. The
actual amount is yet to be negotiated and it will be uniform for every transaction.
The fee collection will be done via a direct debit from the merchant bank account.
The merchant will also be sent a statement showing the money banked and the
fees charged for the month.

Your task is to write the application for the Smartcard Financial Settlement
System. You are required to only create the daily settlement system and
associated report. The application is to run in the Oracle Database and is to be
written using the PL*Sql language.

The components of the application are

• The Daily Settlement file and a corresponding report

• A report to identify any potential fraud

• System control using a RUN table

• An email to a nominated recipient with the Banking report file as an
attachment

The details of the application follow.

Daily Settlement
Deskbank File
The FSS system will be required to run daily and at the conclusion of the run, will
produce a banking file that will be known as a Deskbank file. The Deskbank file
will be sent to the designated banking organization electronically, most likely using
a secure FTP channel.
The Deskbank file, when run in the banking system will contain information
necessary to credit the merchants bank account with the amount collected by the
Smartcard transactions. The total of the deposits into the merchants accounts is to
be offset by a debit from our working bank account. The total of the deposits and
the debits is to reconcile to zero.
This file is intended to be read by the banks systems.
A sample Deskbank file and the file specification can be found in the Appendix
****See the Note on Minimum Settlement under System Constraints

Daily Settlement Report
In addition to the Deskbank file, your system is to produce a daily reconciliation
report. The report will be used by the business unit and will show the banking
details generated by the Daily Settlement. The report will be created automatically
when the deskbank file is produced, however your system should be flexible
enough to allow the manual creation for a given settlement date.
This file is intended to be read by humans.
A sample report is attached in the Appendix.

Fraud Report
The security department’s role is to maintain the integrity and the validity of the
Smartcard system. They have asked for a Fraud report.
The report is to list all those cards and the associated transactions where there is
suspicion of fraud.
No sample of the report exists so you are free to design a sensible report format of
your own.

RUN Table
The FSS system will run each day and should settle all those transactions that
have not yet been settled. You are asked to create and maintain a RUN table
which should keep track of the run dates and the status of each run.

You must use the run table to ensure that only one instance of the program is to
run at any time. If the program is already running it cannot run again. If the
program is restarted while another session is running then a log message is to be
written into the logging table and the second program instance should terminate
gracefully.

In order to minimize the banking costs we want to run only one settlement process
per day. Use the run table to ensure that only one settlement is run per day.
If the settlement was already run on any day then the program should log a
message to the log table and terminate gracefully.

If the program fails during the run it should log the failure reason to the logging
table, update the run table with a status of FAIL. Also the fail reason should be
written to the Run table so that production support know what needs to be
repaired. The run end column should be populated. In such a situation, where the
settlement failed, your program can be rerun on the same day. The assumption is
that production support will have fixed the problem with the data so they may wish
to run the settlement again. You MUST BE VERY CAREFULL however, that your
program does not duplicate the merchants settlements. This could send us
bankrupt.

The production support personnel will use the run table to assist them in
monitoring and maintaining the system in the event of failures. One record should
be created in this table for each run of the program.

Also, you are asked to maintain a log of your program runs which will enable the
production support team to monitor the progress of your run. The log table will
contain a timestamp and a periodic entry to mark the progress of your system.

Note: The logging is to be done by using the COMMON.log procedure which will
be made available to you. I will show you which table the COMMON.log procedure
utilizes for logging, You are of course free and encouraged to develop your own
logging process.

Email the Daily Settlement Report to a nominated person
This component is optional and only those students that wish to take on the
challenge can attempt this.
The Daily Settlement Report once created can be emailed to a nominated
recipient. I will provide you with the bulk of the code you need to generate the
email. You will need to modify the code I give you to add the file as an attachment
to the email. The code and the full details will be provided on UTS Online.

System Constraints

• The FSS system should settle the transactions only once. It is possible that
a user could restart the program multiple times on a given day. You should
ensure that the settlements are not duplicated. In the cases where the user
tries to run the application more than once on a given day, the system
should not allow. This is to be controlled by the run table. If the program
fails on a day then a rerun is allowable but it is vital that

 Settlements are not duplicated.
 Each transaction is settled if the merchant total is greater than

the minimum amount

• The Daily reports and the production of other reports should be re-runnable
by the users at any time and for any given date.

• The existing FSS system is located on ORALAB in the DBP_ADMIN
schema. Select privilege has been granted on all objects in the schema to
enable you to view the existing data. Your FSS system, when completed
will make up the Smartcard system. It will be standalone, but will also be
integrated into the existing tables. You should not make any modifications
to the existing structure because your changes might ‘break’ other
components of the system.

• The E-R Diagram and specifications for the existing database tables can be
found on UTSOnline under the Assignment tab.

• The daily transaction downloads, from the terminals, will be available in the
database environment and the transaction table will be constantly uploaded
with new transactions as they are downloaded from the terminals. This will
be done by an existing automated process.

• It is anticipated that the transaction tables will grow very quickly. We will
adopt an archiving strategy to move the data from the production
environment into an, as yet, undefined environment. You can not assume
that the transaction data is always available for your use. Note: Archiving of
the transaction data is not in the scope of this assignment

• The bank will charge us a fee for all banking transactions. For this reason
we will not be settling trivial amounts each time the program runs. Total

settlement amounts for a merchant that are less than the designated
minimum amount will not be settled in the daily transactions until the total
settlement amount, during the month, reaches the minimum settlement
amount. At the end of the month, any transactions that have not been
processed during the month are to be finalized, irrespective of the amount.

• The minimum settlement amount is configurable and is stored in the
FSS_REFERENCE table under the identifier of Daily Minimum Settlement

• The reload of the Smartcard and the subsequent collection and banking of
the reload money is not a component of this system.

• The Deskbank file name will take the following format
[StudentNumber]_DS_DDMMYYYY.dat for the daily file and
The report file name format is
[StudentNumber]_DSREP_DDMMYYYY.rpt
Note that DDMMYYYY denote the day, month, year of the settlement date when the
deskbank file is created.

When your system runs it will produce three files and an email.
The files are
The deskbank banking file
The Banking report file
The fraud report (Optional)

An email will be sent to a nominated recipient with the Settlement report as
an attachment (Optional)

• So that life is made easier for Laurie while automatically testing the system,
you must follow the naming convention below

Module Name
Package Pkg_FSS_Settlement
Daily Settlement DailySettlement
Daily Banking Summary DailyBankingSummary
FraudReport FraudReport

Example
To run the daily settlement I will type
Pkg_FSS_Settlement.DailySettlement;

To run a report for today I will type
Pkg_FSS_Settlement.DailyBankingSummary

To run a report manually for a different date, say 18-MAR-2018 I will type
Pkg_FSS_Settlement.DailyBankingSummary(‘18-MAR-2018’)
