Requirements and Specifications of the UNIX Application MERCHANT

The application called MERCHANT with the Version 2.1.0.0 is being packaged into a PIF product. The application and how it works is not described in detail, but the requirements of the application are determined, as follows:

• The application runs on any UNIX or Linux operating environment.
• The application consists of a Java GUI, provided as a Java archive file called merchant.jar. The shell script run_merchant.sh starts the GUI. This shell script is linked into the /usr/bin directory.
• Any application data is stored in an Ingres Enterprise Relational Database (Ingres).
• The database tables are created after the product has been installed. The user-written script create_tables.sh will handle this.
• The user should be able to choose the installation directory; the default path is preset with the value /home/merchant.
• An installation dialog is used to determine the installation directory.
• The shared library libi8n.so provides an interface to print localized messages. It is installed once and used by different products.
• The product shows localized error messages, provided by the text files merchant.enu (English messages) and merchant.deu (German messages).
• The installation dialogs are able to provide English or German dialogs.
