The school network billing system and the campus card payment system interface are among the most undervalued parts of the project. School card systems have been in operation for many years, with old technology stores, irregular interfaces, and maintenance teams familiar with the old system.——Each of these is a hot spot for complaints.
Confirmed."Who's in charge?"Start again.
School network billing systems and campus cards interfaces, first of all, with a clear identity of the lead. Campus cards are the core payment system for schools, involving financial compliance, security audits, financial reconciliations, and change costs. The costing system is relatively independent business systems, dominated by suppliers. In these two matches, work can be deadlocked if the lead is not clear.——The provider of the system said"We'll wait for the campus card to change the interface."The campus card team says,"By our standards."The information centre is proposed to be the lead player, coordinating the rhythms of both parties and avoiding direct contact between suppliers and the team.
Make the interface field clear
The school network billing system and the campus card match appear to be simple (school number, amount, time), but there are many details about the actual matching. For example, the format of the sign (card number, coding, identity card number, which is the main key), the unit of the amount (mode, corner, fraction, integer or float point), the time format (time stamp, string, time zone), the code for the transaction type (fill, consumption, refund, withdrawal). Each field is documented and it is best to have a cross-reference table. When the two teams understand the field in a coherent manner, the docking is not always easy to make errors.
Reconciliation mechanisms can't be avoided
The biggest pit for the payment of interlocking is a failure to reconcile.——The school network billing system must design a daily reconciliation mechanism: the logs of each side ' s transactions for the previous day are compared at regular intervals (e.g. 2 a.m.), and discrepancies are entered into the reconciliation anomaly sheet, which is manually verified. The reconciliation has to be processed in full: differences are detected, reasons are identified, data adjusted, records processors are recorded.
Refund process to be designed separately
Students may need refunds after they've filled.——The refund process is often ignored when the system is designed, and it is not easy to find that the first refund occurs. The logic of the school network fee system for refunds is clear: what can be done, how much, who will approve it, whether the refund has been returned or transferred to the balance of the campus card, and how the refund will be processed. Each link requires a responsible person. If third party payments (such as micro-mail, treasure) are made, the refund will have to follow a third party reconciliation, which will take longer periods.
The unusual must be handled in a pre-emptive manner.
There are many different types of anomalies for payment: network interruptions lead to unknown trading status, campus card system failure, system writing failures, third-party payback timeouts."Not completed"The system is to be switched to when the card system is blocked."Suspended fees"Mode, avoid user access but not chargeable"White sex". The plan is to be written into an operation manual and train the crews not to wait until an accident occurs.
Security compliance is the bottom line.
The payment docking involves financial compliance, and the school network billing system is particularly cautious in this area. User passwords cannot be stored explicitly, transaction data must be transmitted encrypted, operational logs should be fully recorded, sensitive operations (e.g. refunds, rate changes) need to be approved. These compliance requirements are not just technical issues but also a process of matching campus card teams, finance departments, audit offices. Compliance requirements require clarity at project start-up, avoiding audits that go online but not back to re-engineering.
Reconnected transport coordination mechanism
The connection is only a start, and the school card system and the school network billing system are to be coordinated over time during subsequent shipments. It is proposed that regular communication mechanisms be established: weekly short, monthly data-recycling sessions, and joint system inspection meetings per semester. Problems encountered in the feeder are synchronized in time, not individually.——The system is very inefficient in the later stages of a project if it doesn't work out.
