Software architecture and design (VII) -- interactive architecture

Interactive architecture

The main goal of interaction oriented architecture is to separate the interaction between users and data abstraction and business data processing . The interaction oriented software architecture decomposes the system into three main partitions -

• Data module - The data module provides data abstraction and all business logic .

• Control module - The control module identifies the flow of control and system configuration actions .

• View the demo module - The view demonstration module is responsible for the visual or audio presentation of data output , And provide user input interface .

• There are two main styles of interaction oriented architecture - Model - View - controller （MVC） And render abstract control （PAC）.MVC and PAC Propose three component decomposition , And for interactive applications , Such as having multiple sessions and user interaction Web Applications . Their control and organizational mobility are different .PAC Is an agent-based hierarchy , but MVC There is no clear hierarchy .

Model view controller （MVC）

MVC Decompose a given software application into three interconnected parts , These parts help to separate the internal representation of information from the information presented or received to users .

modular	function
Model	Encapsulate basic data and business logic
controller	Respond to user actions and indicate application flow
View	Format and present the data from the model to the user .

Model

The model is MVC A central component of , Directly manage application data , Logic and
