Time Series Databases(TSDBs)

A new tool for storing time series data within InfoWorks ICM and ICMLive

Provides intermediate storage between external data sources (e.g. telemetry, RADAR and loggers) and the hydraulic simulation engine in InfoWorks ICM.

Stores different types of times series data:• Scalar (1D) and spatial (2D)• Observed data and forecast data

Supports user editing:• Add missing data or delete/change invalid data • Create custom overrides of the base data (what-if scenarios)

Time Series DatabasesBenefits

High performanceRetrieving data from external data sources for every run would be impractical and inefficient

Preserves historical dataRuns can use recent and historical data for analysis of past events

Quality controlProvides a place in which to flag and correct errors in the data for future runs

Version controlEnables use of data as it existed in the TSDB at any past time, makes it possible for any run to use exactly the same input data as any previous run

ICM Live users can create ‘what-if’ edits of future inputs and control settings and mix’n’match these to simulate different forecast and response scenarios
