Preface
On the low-level, SimpleOne is a big relational database that has an interface to manage this database.
The database consists of the tables and columns interconnected in many ways.
Tables are divided into two sets: system tables and functional tables.
The system tables are used for business logic implementation. They store the inner mechanisms placed there by administrators of the system.
Most of them are write-protected to prevent system disruption.
The purpose of functional tables is to store the data models used in the business logic implementation.
