KeyValueStructure¶
Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::DataDescription::KeyValue::KeyValueStructure
Definition¶
Structure of a key-value datastore (organized collection of key-value data). It is described by identifier, contextual, synthetic id, dimension, variable descriptor and variable value components.
Examples¶
The structure described by [Income distribution, Unit id, Period, Income] where Income distribution is the contextual component, Unit id identifies a statistical unit, period is a effective period and Income is the variable of interest.
