Building a 3-tier app using Python programming and Tkinter and SQLite RDBMS
A 3-tier architecture separates its tiers from each other based on the complexity of the users and how they use the data present in the database.
It is the most widely used architecture to design a DBMS. It is composed of Database Tier (data access), Application Tier (business logic) and User Tier (user interface).
The entity diagram of the database is shown below:
