1 NovaStar 5 Software

2 Multi-user web page access to base station database No client access software required User preferences kept on client workstations Client side user interface keeps band width low SQL database design allow open access to database SQL replication used to synchronize master database with backup database servers Linux operation system Reliable and robust operating system Operating system not subject to Microsoft virus attacks Can be installed on virtual servers NovaStar 5 Software Advantages

4 Locally hosted database Data is kept onsite to insure ownership Local access to data continues when external internet access goes down Local database backups Multiple database servers with synchronized database A change in the master database is immediately copied to backup databases through SQL replication Scheduled database backups Intranet database backup to local backup servers Internet database backup to HydroLynx NovaStar 5 Database Advantages

5 Master Server Backup Server Remote Server Database Data collection Work Statio n Work Statio n Work Statio n

6 All NovaStar servers collect ALERT1 and ALERT2 data Satellite and other agency (COE,USGS) imported from internet Use serial and network connections to decoders A serial connection is hard wired and not subject to network outages A network connection allows a NovaStar server to connect to decoders at remote locations Data received from all decoders will be blended before filing in the NovaStar 5 master database In failover mode, data is filed in the local database NovaStar 5 Data Collection Advantages

7 ALERT2 Decoder ALERT1 Decoder ALERT2 Decoder ALERT1 Decoder Network connection Serial connection Master Server Backup Server Remote Server Internet Data Collection

8 Data validation and calibration Incremental precipitation and rating computation Check alarm conditions and notify Trigger equation computation Determine threat level Automate river forecasting Finished data exported to other agencies (NWS) Data edit

14 Database reads and writes can be done from any database server Web page browsers connect to one of the NovaStar 5 database servers to read and write data User login determines role for database access Users have unique login names or share a global name Login names are assigned to one or more user roles A guest role prevents write access to the database User groups limit access to the database Stations, sensors, maps, plots, and reports can be limited to a user group or user name NovaStar 5 User Access Advantages

15 Client side user interface Web page browser user interface requires no training User preferences are kept on user workstation Browser shortcuts provide quick access to pages NovaScore feature of database flags significant data Alarm triggers set data report score values Score values highlight data on maps and in data tables Links on data provide drill down functionality Edit data reports Check point parameters Recalibrate data NovaStar 5 User Interface Advantages

26 Data can be shared by NovaStar 5 web page Scheduled reports can prepare data for public access Reports can be text, xml, html, graphic maps, plots. Reports can be pushed to another server Reports can be pulled from another server Public web page hosting Customized web page hosting with Apache server Limit public access to prevent denial of service attacks Pull data from NovaStar 5 database for public page display or google maps Create control pages for roadway signs.
