Database
Data Model
The database is made up of user-facing views and their underlying tables -
Views (in the public schema):
devices - a list of available devices
dataitems - a list of all device dataitems
history_all - history containing both text and numeric values
history_text - history with only text values
history_float - history with only numeric values
Tables (in the raw schema):
nodes - stores device and dataitem definitions
edges - will store connections between nodes
history - stores historical values for dataitems
meta - stores database version information
