Framework System of Enterprise architecture

Basic concepts

FRAME (framework): is to deal with a certain type/certain aspects of the idea/approach, through a large number of early research, try, adjust, refine, validate, design and summarize a set of common, feasible methods and knowledge of the organizational structure, can help others to deal with similar problems. is a macro, high-level guidance, but the framework is not a standard answer, there is no direct result, need to understand the basis of flexible use.

Methodology (Mehtodology): is a method and tool of a specific problem, the methodology will be a series of specific methods of analysis, systematic summary and finally put forward more general principles. Methodology is an integral part of the enterprise Architecture framework, and the breadth and height of the framework require support from many methodologies.

Enterprise Architecture Scenario (approach): An enterprise or project that, according to its own circumstances, refers to a wide range of enterprise architecture frameworks and methodologies, tailored to a solution. With floor-to-ceiling, more detailed and enriched.

Business Architecture

The business architecture is the most influential part of the entire enterprise architecture, but also the most controversial part. As the initial enterprise architecture includes only the content of it, as the theory continues to evolve and improve, the business architecture is gradually becoming part of the enterprise architecture. But more companies have yet to incorporate the business architecture into the enterprise architecture.

The business architecture is the foundation of a comprehensive IT strategy and it architecture, as the business architecture is driven by applications, data/information, and technology. Before you begin to design your IT architecture, you need to have a deep understanding of your business architecture.

How to design a business architecture: business Processes

Many frameworks, such as FEAF (Federated Enterprise Architecture), use business processes directly to represent business architectures, and there are many mature process methodologies that can be consulted, such as APQC, which divides processes into core processes and ancillary processes, and provides a common process framework for reference.

Application Architecture

The application Architecture (application Architure) is a description of what IT system functions and technology implementation. The application architecture is divided into the following two different levels:

Enterprise-level Application Architecture: Enterprise-level application architecture plays a unified planning, connecting the role of the enterprise to undertake the strategic direction of development and business model, downward planning and guidance of enterprise each IT system positioning and function. In the enterprise architecture, the application architecture is the most important and the most workload part, he includes the Enterprise Application Architecture Blueprint, architectural standards/principles, system boundaries and definitions, the relationship between the system and other aspects of the content.

Application architecture for a single system: when developing or designing a single IT system, the main modules and function points of the system are designed, and the system technology implementation is from the front-end to the business processing logic, to the background data is how to structure. This work is generally part of the project team, not the enterprise architecture, but the architecture design of each system needs to follow the enterprise's overall application architecture principles.

The application architecture mainly describes the composition and framework of the system in the form of architecture diagram, which is generally designed from two architectural perspectives: system function and system technical level.

Data architecture

The data architecture mainly involves the classification of enterprise data (which belongs to the work of data standardization), the distribution and circulation of data, and other contents.

One: Data classification

Second: data storage and circulation

Technology architecture

The technical architecture contains a wide range of content, from the development framework, operating system, middleware, security, equipment, network to deployment, disaster preparedness, and so on, depending on the circumstances of different companies and projects to determine the extent of technical framework and control. For more complex and mature enterprises, infrastructure such as equipment and networks can be excluded from the technical architecture. is one of the most comprehensive technical framework scope, can refer to the scope of the enterprise:
