Three Tier Architecture Presentation

Introduction to Three Tier Architecture
• Three tier architecture is a software design pattern that divides an application into three separate layers.
• The three layers are presentation layer, business logic layer, and data storage layer.
• This architecture provides modularity, scalability, and easier maintenance of the application.

Presentation Layer
• The presentation layer is responsible for the user interface of the application.
• It focuses on the interaction between the user and the application.
• This layer includes components like web browsers, mobile applications, and graphical user interfaces.

Business Logic Layer
• The business logic layer contains the core functionality and rules of the application.
• It handles the processing and manipulation of data.
• This layer is responsible for implementing the business rules and workflows.

Data Storage Layer
• The data storage layer manages the storage and retrieval of data.
• It includes databases, file systems, and any other data storage mechanisms.
• This layer ensures data integrity, security, and efficient data access.

Benefits of Three Tier Architecture
• Improved scalability: Each layer can be scaled independently, allowing for better performance and resource utilization.
• Enhanced modularity: The separation of concerns makes it easier to modify or replace individual layers without impacting the entire application.
• Simplified maintenance: With clear boundaries between layers, troubleshooting and debugging become easier, leading to faster maintenance and updates.
