The system is a client–server application for Windows OS for LAN at location’s office. However, due to elaborated TCP/IP design of the transport layer, the system is easily deployable on wide area network as well. The rich user interface is built upon Infragistics NetAdvantage package. The installation and upgrades of the applications are done with the wizards, created with the help of InstallShield. The PDA clients were designed to work offline with online synchronizations with the main system.
