Database Structure Reference

This page contains the reference documentation of RacksDB database structure, with all objects models and properties. The document starts with a legend of some symbols used for schematic representation of properties. Then, the root content of the database is described, followed by all subsequents objects. At the end, the defined types are described.

Symbols legend

Some icons are used in the tables of this page for symbolic representations of advanced data types:

Other symbols are used for attributes of properties:

The optional/required attribute is indicated in the Required column of properties definition table. When defined, the default value attribute is mentioned in the Description column.
