Course Description

N-Tier and REST are both architectures used for developing applications. By using the N-tier architecture, model developers can create applications that are flexible and reusable. In this course you will explore how the N-tier architecture provides a means to separate an application into tiers to allow the developer to add or modify a specific layer instead of recreating the entire application. You will also learn about the Representational state transfer, or REST, architecture and how it utilizes HTTP requests to post, read, and delete data, and perform CRUD operations. Finally, you will learn how to design and build applications based on both the N-tier and REST architectures.
