Architecture

Backend

• Project backend is based on a 3-layer architecture, specifically controllers, service, and DAO layer.
• Controllers exposes the API end-points. Controller class accepts all api request which are then passed to the service layer.
• Service layer takes care of the bussiness logic before doing database access.
• DAO layer acts as an interface between the database and the service layer.
• Basic authorization is implemented using Spring security

Frontend
