Technological aspects The overall software environment consists of: The overall software environment consists of: The Core API, and The Supporting Application The Core API, and The Supporting Application While The Core API (which is completely independent of the business rules) has reached it’s final shape, The Supporting Application (highly dependent of the business rules) may be of numerous favours, two of which are to be described. The deeper explanation of both the Core API and the Supporting Application follows. While The Core API (which is completely independent of the business rules) has reached it’s final shape, The Supporting Application (highly dependent of the business rules) may be of numerous favours, two of which are to be described. The deeper explanation of both the Core API and the Supporting Application follows. 1.1 Core API 1.1 Core API The Core API (Application Programming Interface) is a JAVA Bean that provides the methods for sending an SMS to a given mobile phone number programmaticaly from a JAVA based software environment (stand-alone application, JSP, Servlet...), via GSM mobile phone connected to a serial port of a host computer. At the moment, the API is furbished and ready-to-use.

Finally, the infrastructure needed for both approaches is summarized in the table below. Desktop Application``````````````````````````  GSM phone with data cable  Database Server  Desktop Computer with at least dial-up Internet access running Desktop Application  Full-time enrolled human operator(s) [who will abuse the phone-line, and waste space, water and electricity]  GSM phone with data cable  Database Server  Web-Server with 24/7 Internet access running Web-based Application  Public key certificate  Part-time enrolled or even tele- commuting Database and Web-Server administrators Both approaches are JAVA-based and therefore no investment in software is needed since free JDKs (JAVA Development Kits), JREs (JAVA Runtime Environments) and Web-Servers supporting JSP (JAVA Server Pages) and Servlets are available for most platforms. RDBMS (Relational Database Management System) with JDBC connectivity is a must, but it is not a problem since wide variety is offered, from free pocket-rocket (like PostgreSQL) to expensive, full-blown (like Oracle, Microsoft SQL Server or IBM DB2).
