[software architecture] several points to be considered in software architecture design

Software architecture design and system design are very different. Architecture design focuses on software framework construction, software quality characteristics and system decomposition, mainly involving the following aspects:

The goal of software architecture is very positioning, determine the market positioning of target software, etc.;

Software quality attributes and their priorities, such as high performance, scalability, openness, customization and other attributes to determine;

architectural constraints;

Architecture principles require clarity about what software is and isn't;

The overall design of the architecture

Software system decomposition and its responsibility definition, including system context and functional structure;

Subsystem design, including subsystem module division, interface design and key data design;

Physical deployment of software;

the composition of the software package and the installation method;
