System design is the process of creating a system, which is a collection of components that work together to achieve a common goal. The system must be designed before it can be built, and the design process is critical to the success of the system. One of the most important aspects of system design is the architecture of the system.
The architecture of a system is the structure of the system, and it determines how the system will work. There are many different architectures, and each has its own advantages and disadvantages. One of the most popular architectures is the 3 tier architecture.
The 3 tier architecture is a client-server architecture that separates the system into three tiers: the client tier, the middle tier, and the server tier. The client tier is the tier that the users interact with, and it contains the user interface and the business logic. The middle tier is the tier that contains the business rules and the data access components. The server tier is the tier that contains the data and the application logic.
The 3 tier architecture is a popular architecture because it is scalable and it is easy to maintain. The client tier is thin, which means that it doesn’t contain any business logic or data. This makes it easy to update the client tier, and it also makes the system more scalable because the client tier can be distributed across multiple machines. The middle tier is thick, which means that it contains the business logic and the data access components. This makes the middle tier more reliable because it contains all of the essential components. The server tier is thick, which means that it contains the data and the application logic. This makes the server tier more reliable because it contains all of the essential components.
