Object Data Base: Time Series (Monitoring) Data)
The object oriented data base in WaterWare is implemented on industry standard relational data base engines
(RDBMS) such as ORACLE, MySQL, or PostgreSQL, with a high level of normalization.
The data base implementation supports basic numerical, symbolic, and hypermedia formats (text, imagery, video),
as well as an easy-to-use interactive menu driven interface,
and display, editors, and analysis tools. OBJECTS are dynamically instantiated when accessed,
so the system is always up-to-data, in real time.

Time Series Data: WaterWare data management for monitoring time series includes a fully configurable
download option (interactive user interface) from SQL data bases;
alternative methods/strategies include data capture via any TCP/IP based protocol.
Download via dedicated dial-up connections with sensor/data logger specific protocols can be added,
provided a clear description of the required access methods and protocols is available.
Configuration includes stations, variables, time steps, and the protocol specific access parameters.
Data access is fully automatic, based on cron and an independent (parallel) watchdog
A range of tools support e.g., basic statistical analysis, quality control, outlier detection,
comparison between stations or against standards or target values, including model validation tasks.
The time series data include both monitoring data (historical and real-time), together with model
generated time series (flow, levels, evapo-transpiration, infiltration (all components of the water
cycle at the nodes and reaches of the river basin network representation), associated costs and benefits,
and water quality data.
