What is Multi-tier Architecture ?
The most important problems for a programmer are how to access the data in applications, what applications will be made on it and how to present to the user side. The multi-tier architectural approach also separates this complex structure according to responsibilities, functionalities, tasks, thus enabling simpler and more manageable applications. Because in the programs prepared by separating into layers, each action is designed separately and it is clear what is where. Thus, in cases where intervention is required, this process is performed easily and without wasting time.
