2.2 PSS Software Overview
Built upon the WaveWorks core software, the PSS software consists of
• COM Objects
• NT Services
• Display Server Scripts
• Database
The COM Objects and NT Services perform the business logic. That is, they are responsible for
the data manipulation and system sequencing that makes the system a portable shopping system.
The methods contained in the COM Objects and the NT Services are invoked via WaveWorks
transactions. The COM Objects are dynamically created and deleted by the Business Server. The
NT Services are started at system startup and remain resident in the system.
The Display Server scripts provide the user interface mechanism for the hand held terminals and
entrance units. The scripts define the screen layout and provide the handling of user actions for
those devices. When necessary, the scripts invoke business methods via WaveWorks
transactions.
The database contains all of the persistent data of the system. The database is used to store all
information about the devices, shoppers, items, and system configuration as required.
2.3 Major Subsystems
2.3.1 Unit Management Subsystem
The Unit Management Subsystem (UMS) manages the Symbol hardware devices that comprise
the PSS system. Those devices include hand held terminals, cradles, entrance unit devices, ticket
printers, and power supplies. UMS ensures that the devices work in concert with one another to
provide a seamless integrated system.
2.3.2 Shopping Trip Subsystem
Once the shopper retrieves the proper hand held terminal from the dispenser, the Shopping Trip
application allows the shopper to add and delete items from their basket and view the “totals”
information for their current shopping trip. Shopping trips can be ended by returning the hand
held terminal to an empty dispenser slot or by scanning an “End of Trip” barcode. Each activity
during the shopping trip is logged and available for review from the Service Terminal.
