Questions and Answers

What is multi-tier architecture in software engineering?

Multi-tier architecture is a client-server architecture in which presentation, application processing, and data management functions are logically separated.

What is the purpose of using multi-tier architecture?

The purpose of using multi-tier architecture is to create flexible and reusable applications by segregating an application into tiers.

What is the most common form of multi-tier architecture?

The most common form of multi-tier architecture is the three-tier architecture.

What are the three tiers in a typical three-tier architecture?

<p>The three tiers in a typical three-tier architecture are the presentation tier, the business or data access tier, and the data tier.</p> Signup and view all the answers

Why is the use of N-tier architecture beneficial?

<p>The use of N-tier architecture allows developers to modify or add a specific layer instead of reworking the entire application, making it more flexible and scalable.</p> Signup and view all the answers

Study Notes

Multi-Tier Architecture in Software Engineering

  • Multi-tier architecture is a software architecture pattern that separates an application into multiple layers or tiers, each responsible for a specific function or set of functions.

Purpose of Multi-Tier Architecture

  • The primary purpose of using multi-tier architecture is to improve scalability, maintainability, and reusability of an application by dividing it into independent layers that can be developed, updated, and scaled independently.

Common Form of Multi-Tier Architecture

  • The most common form of multi-tier architecture is the three-tier architecture, which consists of three separate layers: presentation, application, and data storage.

Three-Tier Architecture

  • In a typical three-tier architecture, the three tiers are:
    • Presentation Tier: responsible for handling user input and output, and providing a user interface for the application.
    • Application Tier: responsible for executing business logic, processing data, and implementing functionality.
    • Data Storage Tier: responsible for storing and retrieving data, and providing data access to the application.

Benefits of N-Tier Architecture

  • Using N-tier architecture is beneficial because it:
    • Improves scalability and flexibility by allowing each tier to be developed and updated independently.
    • Enhances reusability by allowing components to be reused across different applications.
    • Facilitates easier maintenance and troubleshooting by isolating issues to specific tiers.
    • Provides better security by separating sensitive data and business logic into separate tiers.
