Central Station - 5073NS/NovaStar 5 Software

MODEL 5073NS-5 : NovaStar 5 Software

General Description:

NovaStar5 Software from HydroLynx is a real-time data collection, alarm monitoring and control system. NovaStar5 runs under the Linux operating system. The Linux operating system is stable, non-proprietary, well known, and trusted by IT managers.

The NovaStar5 database uses Postgresql. This is a powerful, open source, non-proprietary, SQL database. This ODBC SQL database allows remote access to the data from third party software. The database tables can be viewed and modified with a graphical user interface administrative tool.

The NovaStar5 database can be mirrored over a local area network, LAN, on a hot backup server. A LAN failover system maintains redundant databases on two NovaStar5 servers and does automatic failover if the primary system fails.

The NovaStar5 user interface uses web pages to simplify user access to the database and system operations. The web page user interface is client based and runs on any internet browser. Local access on the NovaStar5 server, office intranet access, and remote internet access is supported.
