Lao Tzu's path to software-Article 21 enterprise application architecture

Abstract: Lao Tzu's philosophy, morality, software philosophy, and software reference: top ten programming rules for eliminating human wolf software in sequence

SAGE:Kong de's only path is from. The path is "thing", but "nothing. Which has an image. There is something in it. Some of them are excellent. Its essence is very real, and there is a letter in it. Since ancient times and today, its name has not been used to read the crowd. How can I be like a good person! .

The scientific enterprise application architecture (EAA) is built based on the software. Although its forms are diverse and varied, they all have a common framework (image) and Constructor (thing), which contains the most precise components, and the most basic metadata (information) that constitutes these Precision Components, only in this way can we grasp the fundamentals of the software. This data is the most basic and true. Through it, we can grasp the source of the Software. How can I understand the software path, it depends on this.

We can see from a higher abstraction level that any application system inputs, outputs, transfers, processes, searches, and stores data, if we cannot manage and use data in an application field, we will not grasp the foundation of the software. A specific data element will appear repeatedly in various parts of the software system, for example: tables, classes, variables, transmission parameters, interfaces, printing and output, etc., but most software development processes do not centrally manage and use data elements, each of which is manually written by programmers, therefore, it not only increases the workload of manual programming, but also leads to frequent inconsistencies, which leads to difficulties in various stages of development and testing, especially when the length of the Data Type changes, it will bring about a lot of modification and debugging workload. In an application system, the same data element has only one unique definition, and all other parts that use the data element are referenced by the unique definition. The problem is solved. I pointed out the direction for us two thousand years ago. "I believe it is very accurate ".
