Source: https://www.simform.com/blog/software-architecture-patterns/ 1. Layered Architecture Pattern You’ve probably heard of multi-layered, aka tiered architecture, or n-tier architecture. This architecture has gained popularity amongst designers and software architects alike for its commonalities with the conventional arrangements of IT communications in many startups and established enterprises. Often, a layered architecture is classified into four distinct layers: presentation, business, persistence, and database; however, the pattern is not confined to the specified layers and there can be an application layer or service layer or data access layer. Popular frameworks like Java EE utilized this architecture pattern. Let’s say a software engineer is building a large application, and you employed all four layers to your architecture pattern. On the flip side, small businesses may combine the business and the persistence layers into a single unit, primarily when the latter is...
