4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
Primary Concern: It is easy to be too detailed by including many different needs in a single diagram. This should be avoided. It is better to draw multiple diagrams, one for each viewpoint, than to draw a 'mega diagram' that is extremely rich in content. Remember this: when building houses, the architect delivers many different diagrams.
Software architecture pattern is a reusable, proven solution to a specific, recurring problem focused on architectural design challenges, which can be applied within various architectural styles. [ 1 ]
High-level design (HLD) explains the architecture that would be used to develop a system.The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.
Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML) , Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE) .
Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. There are two fundamental laws in software architecture: [3] [4] Everything is a trade-off "Why is more important ...
Software architecture description is the set of practices for expressing, communicating and analysing software architectures (also called architectural rendering), and the result of applying such practices through a work product expressing a software architecture (ISO/IEC/IEEE 42010).
[1] An SDD usually accompanies an architecture diagram with pointers to detailed feature specifications of smaller pieces of the design. Practically, the description is required to coordinate a large team under a single vision, needs to be a stable reference, and outline all parts of the software and how they will work.
