Architecture description

DTO

Data transfer objects are objects with all user input properties. DTOs should contain a static validate method which returns an array of express-validator rules for validating user input.

Response models

Response models are objects which are representations of response data.

Database entities

Database entities are sequelize models which are used to connect with the database.
