No matter what your chief architect or technology person in charge or, you have to admit, all technical and infrastructure services are for business, out of business, architecture is a mass of paper.
Today gave you talk about business architecture, business architecture and construction from 0-1.
First-defined application architecture, can be learned from the Baidu Encyclopedia What is Application Architecture:
Application Architecture (Application Architecture) is a description of the contents of the IT system functionality and technology. Application architecture is divided into two different levels:
- Enterprise application architecture: enterprise-level application architecture plays a unified planning, the role of connecting up to undertake the corporate strategic direction and business model, positioning and function down planning and guidance of each enterprise IT systems. In enterprise architecture, application architecture is the most important and largest part of the work, including the content of his enterprise application architecture blueprint architecture standards / principles, boundaries and definitions of the system, such as relationships between systems.
- Application of a single system architecture: when developing or designing a single IT system, system design and function of the main modules point, technology systems is to show from the front end to business processing logic, to the background of how the data is architecture. Work in this area is generally within the project team, rather than the scope of the enterprise architecture, but the architecture of each system need to follow the general framework of the principle of enterprise applications.
In short, the application architecture diagram into two categories, one is a multi-system application architecture for hierarchical description service logical relationship between different systems, traffic, etc. the system boundary. One for the single-system application architecture, for sub-service logical relationship among the main components of the modules and functions described point system level.
Or by job description from the perspective of application architecture diagram, the system is divided into functional architecture diagram (or called business architecture diagram) and system-level architecture diagram (or call technical architecture diagram). Difference between the two is as follows:
In general, since the Internet is now increasingly focused on the company's product manager functional design and business decisions, while technical staff are more focused on the technical design. So for product managers, application architecture diagram focuses on the business architecture diagrams, technical architecture diagram by the technical manager in charge. Of course, product manager if there are technical background, we have the ability to better understand the technical architecture plans.
The following were cited showing an example of architecture of the Internet made the god to explain what is business architecture diagram, what is the technical architecture diagram.
Technical Chart
Technology architecture diagram, from the network, intrusion deleted
Seen from the figure, the characteristics of the architecture of FIG art techniques is that the language used to describe the seven-level system.
Business Chart
Business architecture diagram can be explained by multi-system business structure and single-system view of business architecture map.
Multi-system business architecture diagram
From "Deep | Speaking from a story, talk about the history of the evolution of Enterprise Application Architecture" by Yang Kun, invasion deleted)
, Business architecture diagram is the starting figure seen from the perspective of the business logic, product manager level and neatly show a relationship between the various categories of systems. Yang Kun in the Great God "depth | Speaking from a story, talk about the history of the evolution of enterprise application architecture," a paper, we describe the image for the business process architecture diagram from scratch, very worthy of our product people learn . Here the experience of the power of God say about their understanding of the business architecture map.
Business architecture diagram in accordance with the hierarchy can be divided into classic three-tier architecture: presentation layer, business logic and data layer, while the figure of the basis, they are for the presentation layer and business logic layer made segments. In fact, on the basis of FIG can also add one layer operation and maintenance system will be explained the hardware required conditions. Especially important in terms of a single system architecture diagram.
System Architecture FIG multi another advantage is that, whenever a new subsystem, which can predict in advance whether or unit need to share business logic. For example, whether to use the same set of accounts system, which is essential for early development products.
Single business system architecture diagram
For a product manager in addition to understanding the positioning of the project across the entire enterprise application architecture, but also have a clear hierarchical design and understanding of the modules and functions of the entire system from the project in terms of 0-1. So it is not only multi-product manager of business systems architecture diagram, also require a single business system architecture diagram.
Single-system application architecture diagram
Can be seen from the figure, single-layered system architecture diagram can be applied and consistent multi-system application architecture of FIG. But inside each level of description unit becomes functional modules, instead of subsystems.
Application architecture diagram looks not so much the specific function and design, but this time there is a mind map, you can go to design systems from the overall situation, the layout well in advance to avoid the late giant pit.
