Now this way, you can see that there is a good share of modularity, organisation, cohesion, decoupling, isolation, reusability, and flexibility between the software components. Multitier architecture also encourages better discipline and makes it very convenient for collaborations by simplifying code maintenance without any complexities tangling the stack.
The layered architecture is a common practice in a client-server model. Most modern applications have at least three layers when a database is involved. Hence this architectural pattern is also called as a three-tier or n-tier architecture.
