Solutions Engineering was contracted to design a database application for the sales and distribution of tickets for theater, sports, and concert events throughout the U.S.  The client company was Top Centre Ticket Service of Washington, DC ­ the chairman and founding president of the National Ticket Brokers Association.  This system had to handle hundreds of thousands of tickets for hundreds of events at nation wide venues.  The requirements of the system were many and challenging.  One requirement  (for Release 2) was to support the automatic posting of ticket inventory on the web from up to 400 different databases and the sale of tickets on the web synchronized in real-time with the appropriate source database.  The system must be engineered in order to guarantee that each and every ticket could be sold only once ­ no two invoices (generated anywhere) could include the same ticket.  This would have to be supported over an extremely diverse set of WAN (telco/modem, ISDN, DSL, frame-relay, fractional T1, full T1) and LAN (Static IP, DHCP, Published IP, Unpublished IP, shared protocol, NAT, Proxy Server, Firewalls, …).  The system had to properly execute transactions in the event of a line or node failure as well.  The features and benefits of the POS system are :

The system has been in use since Oct. 1999 with enhancements.  The system performs real-time synchronization between the web server database and the organization local databases ­ properly enforcing the requirement that no single seat ticket can be sold to more than one person.  TM2000 has a fully integrated venue seating chart display capability to allow users to pull up the visual map or seating chart for the venue of an event and automatically (one button action) e-mail the chart to the client currently being serviced.  The system is being integrated with Federal Express on-line services to perform fully integrated service request and shipping status tracking for every shipment.

The system is written entirely in Visual C++, relying entirely on ODBC for data exchange.  This permits remote support and upgrades, as well as enabling optional plug-ins to be provided without requiring any changes to the software or underlying architecture.
