Ans: Zachman Framework is an Enterprise Architecture framework that was developed by IBM during the 1980s. It allows a way to define an enterprise based on a 6x6 matrix of the architecture documentation. The questions like what, when, where, why, who, how are asked by the matrix columns. The rows examine these questions at various levels of detail like conceptual, contextual, physical, logical, and detailed. The Zachman Framework offers a view to planners, designers, owners, subcontractors, and builders. The main objective is that the same can be described for various purposes in various ways. It will create a holistic view. It enables various people to view the Enterprise from various perspectives. The Zachman framework has been integrated into a number of Enterprise Architecture frameworks.
Ans: The involvement of projects during the initial phase is important to make sure that the architecture compliance processes are covered in project planning. When the solution architecture is defined, the compliance assessment must be carried out. The compliance assessment guarantees the project compliance to the enterprise architecture defined. It is a chance to involve project members and obtain feedback for enterprise architecture. The compliance assessment will cover software, information, applications, security, checklists for hardware, system management, and tools and methods. A brief overview of the architecture and design of the project is also documented.
Ans: ISO/IEC 42010:2007 defines architecture as the basic organization of a system, included in its components, their relations with one another and the environment, and the principles by which it is designed and evolved. This definition is supported by TOGAF while maintaining consistency with the terminology of ISO/IEC 42010:2007 but sees the significance of the architecture in a different way depending on the context used. For TOGAF, the architectures are A system's formal description or a system's detailed plan at the component level to guide the implementation.

Ans: During the initial phase of the project, the architecture vision is created. The vision aims to agree right from the beginning on the desired result for the architecture. It is the elevator pitch of enterprise architecture. It must sell the benefits of the proposed architecture simply and powerfully to the decision-makers. It should also demonstrate how the proposed architecture supports the goals and the strategy of the business and the concerns and objectives of the stakeholders.
General contents of the architecture vision are process description, problem description, roles and actors, objectives, architecture overview, IT principles, constraints, and mapping of proposed architecture to the processes and the requirements.
Ans: SOA design patterns are the reusable solutions for SOA design problems that arise frequently. Following are some of the common SOA patterns:
File gateway: It is placed in between the service and the legacy flat file. The gateway will act as the mediator and may carry out the data transformations.
Enterprise Service Bus: It is a tool which promotes service communication by delivering messaging queuing, reliable messaging, service broker functionality, and data transformations.
Service Callback: The service needs customers to communicate with the service in an asynchronous manner. Consumers offer a callback address where the service may send reply messages.
Event-driven messaging: The service informs the customers of relevant events by sending messages.
Service Grid: The service state will be stored on the grid of service, which supports both replication and redundancy.
Ans: It system a set of components designed for providing a particular function or a set of functions.
Architecture: It is the basic organization of the components of the systems, their relations with one another, and the guiding principles of design and growth.
