The contract helps to monitor architectural integrity, standards adherence, and risk avoidance in the solution implementation. Man Month from Fred Brooks is that conceptual integrity is the most important consideration in system design, and that conceptual integrity will only be achieved if the design comes from one,. A single chief architect (or a small number of architects), acting on the user's behalf, decides what goes in the system and what stays out. In the study, we explain the multi-view software architecture design step by step starting with identifying the system context, requirements, constraints, and quality expectations. The evolution of the architecture should be known to evaluate and analyze the software elements. It’s often used for traditional web applications and enterprise applications. Typically, a database designer creates a database schema to help programmers whose software will interact with the database. In particular, it is difficult to draw a sharp line between design and architecture-architecture is one aspect of design that concentrates on some.
