Software Architecture Design-system Overall architecture design

The overall architecture of the system is very important, but it is different in expression, here are some common system architecture patterns for reference:

ASSF (access-service)-standard-fundation mode : Access-Service (business function)-standard-base, the system architecture at all levels are expressed, but the deployment of application patterns need to have a separate description, Organize the overall architecture of the system as shown below:

location mode : Suitable for group-level applications, the application of logical expression is clearer, as shown in the following figure:

3 Management-level Mode : Expresses the function that is used at all levels from the decision-making level-management layer-operation layer. For the system functional expression is more clear, to achieve a consistent understanding with the customer has a good effect, as shown in the following figure:

It is recommended that the ASSF mode be the main structure, and the location model and the 3management-level mode additional description system should be developed, and the system architecture should be expressed from various levels.
