Common knowledge for software development

Why is software development so difficult? The concept is inconsistent with the developed ones, inaccurate workload estimation, and many hidden quality problems ......

Is the requirement not clearly defined? Is the design document not accurate enough? Indeed, from the demand to the product, there are too many details to consider, there are too many variables, and the requirements and design documents are not comprehensive.

However, you cannot ask the architect to take every brick into consideration. Because many links in the building have formed an inherent Convention and have a habit of doing so. Therefore, you do not have
You will know how to describe it. It doesn't mean that the following links are simple, but they are relatively mature. Each link has its own detailed specifications, and relevant practitioners have been trained. Therefore, when
Zhu shi said that the door should be followed. When a sewer is to be dug there, everyone will know how to do it. If you want to describe how the door is shaped, how to install it, and what the door lock is, it's like the bird's nest
Who can do the design?

The software industry has been developing for a short period of time and is constantly changing. We have not yet reached a consensus on many things and have no unified concept. Therefore, when we say we want to do something, we still need to describe the relevant details with great effort, and we cannot guarantee whether it is what we want at last. We need to build more common sense to avoid misunderstanding and reduce communication costs.

DSL (collar
Domain-specific language) is an attempt to establish a dedicated modeling language for software applications in each industry. Because each domain has its own proprietary concept and specific domain knowledge, you can use a specific modeling language.
To be accurate and concise. With the deepening of industrial applications, everyone will naturally reach a consensus (common sense) to form standards. Everyone will know how the software applications in each industry look like, the results of software development become predictable, and the quality is guaranteed.

In our daily life, we also need to do things according to common sense and practice, so that individuals can perform their respective duties in order to be methodical.
