Relationship between pyORM and your RDBMSΒΆ

There is a direct one to one relationship between classes, _fields, instances and relationships and data structures within a relational database :

pyOrm construct Relational Database construct
Models Tables
Fields Columns
Field Attributes Column Constraints
Model instances Rows in Tables
Mappings between Models Joins and Keys between Tables

Using these Models, _fields, and relationships, the application will be able to build QuerySets which in most cases remove the need for the application writer to create SQL statements, since pyORM takes care of ALL of
