Delft-FEWS has been developed using JAVA technology and can be equally deployed on Windows, Linux or Unix servers. The system is fully configurable using open XML formatted configuration files. The Delft-FEWS configuration manager manages and analysis the configuration.

Deployment of Delft-FEWS system software is very straightforward without the need for a formal setup procedure. Delft-FEWS has no external dependencies and does not require any other software to be installed in the system. Installation and version control for computer system administrators is therefore limited to a simple file copy procedure.

modes of operation

Delft-FEWS can be configured to run in two different modes of operation: stand alone and client server. The principal difference between the two modes of operation lies in the way forecast runs are carried out.

In stand alone mode forecasts are run and analysed manually on a single computer. Data can be received and imported from external sources and reports can be published to a webserver.

Alternatively the system can be configured to be used a full J2EE compliant client server application. To enable this, Delft-FEWS is extended with the Delft-FEWS Master Controller. The Master Controller is responsible for all task scheduling, control of the central database, load balancing of application servers and data synchronisation. For enhanced resilience two master controllers may be used in a Duty-Duty or in Duty-Standby configuration . Established standards such as Java Messaging Service ensure smooth and resilient communication between clients and servers.
