The communication between system analysts and customers should be based on the use case diagram. the use case diagram is intended for customers.
Here, you should pay attention to it. Don't underestimate the use case diagram. You must save it and everyone will get it later!
The customer is willing to pay when he sees the use case diagram, and will forget what he said! As the saying goes, it's just plain-spoken and black!

5 Environment switching
In general, our framework will have several sets of environments: formal, test, local, sandbox, etc., different environment configuration will certainly be different. Laravel allows the current configuration environment to be specified at the start of the process, enabling automatic switching between different environments.

A core issue of software architecture design is the ability to use repetitive architectural patterns, that is, the ability to achieve architecture-level sof
architecture requires the architect to have good (rich) business knowledge in addition to technical and architectural design capabilities. From the perspective of software engineering, architects are required to participate in the requirements analysis phase, development, testing, release, commissioning phase, in addition to participating in the

elements that make up the system, the interactions of these elements, the patterns that guide the integration of elements, and the constraints of these patterns. The software architecture not only specifies the organizational structure and topology of the system, but also shows the correspondence between the system requirements and the elements that make up the system, and provides some basic principles of
Evolutionary architecture (evolutionary architecture) and emergency design (emergent) are agile technologies that postpone important decisions to the last-minute responsibility (responsible Moment). In the first installment of this series, Neal Ford, a series author, will define the architecture and
What is the architecture of the software System (architecture). Generally speaking, the architecture has two elements:• It is a software system from the overall to the part of the highest level of division.A system is usually made up of components, and how these elements for
