Batch Reporting Process and Transactions

Specialized Hardware
:The batch processing component is installed on a dedicated physical platform which has a network connection to both the head office computer system as well a connection to the pumps. This specialized hardware also houses the software for the interactive login component.
Security and Performance Considerations:
Security is handled exclusively by other components of the system. The batch processing subsystem is connected only to other subsystems of AGS and the head office through a direct (cable) connection. The hardware specially designed for this system insures security and prevents any tampering with the system.
Performance issues break down into two main categories:
Crash-protection: It is essential that this system not crash during its operation. This is accomplished in large part by carefully designed hardware. At the software level, the batch-report system is the most critical portion of the system. If this system breaks down it will be impossible to preserve a record of activities by the system. Therefore any critical problem as far as is possible will immediately generate an emergency call to the head office. Also, a backup of all data is made on a regular basis to allow the system to be brought back up gracefully if it should fail.
Speed: Clearly a customer should not wait for more than a few seconds for his transaction to take place. Once a transaction is processed, the pump sends the data for the transaction to the batch processing system where it is integrated into the system with the existing data. This process is virtually instantaneous. Even if a large number of gas stations send transaction data at the same time, the system should not take more than a few seconds to respond.
Functions of the Batch Subsystem:
The system requirements addressed by the batch subsystem component are as follows:
The following information will be received by the batch processing subsystem from both the head office and other subsystems:
Transaction data from each of the pumps associated with the system.
Requests for reports from interactive login subsystem.
Request for report-generation scheduling changes from interactive login subsystem.
The following information is reported on by the batch processing subsystem.
Batch output of reports to central office system.
Output of reports to interactive login subsystem (per request).
Reports and Actions:
The batch reports sent to the head office will contain the following information for each transaction processed by the gas station:
