concern

In computer science, a concern is a particular set of information that has an effect on the code of a computer program. A concern can be as general as the details of database interaction or as specific as performing a primitive calculation, depending on the level of conversation between developers and the program being discussed. IBM uses the term concern space to describe the sectioning of conceptual information.

Usually the code can be separated into logical sections, each addressing [致力于] separate concerns, and so it hides the need for a given section to know particular information addressed by a different section. This leads to a modular program. Edsger W. Dijkstra coined the term "separation of concerns" to describe the mentality behind this modularization, which allows the programmer to reduce the complexity of the system being designed. “铁路警察各管一段”。

Two different concerns that intermingle [inter和mingle都是词] in the same section of code are called "highly coupled [耦合]". Sometimes the chosen module divisions do not allow for one concern to be completely separated from another, resulting in cross-cutting concerns. The various programming paradigms [范式] address the issue of cross-cutting concerns to different degrees.

耦：两个人在一起耕地。

grain: 纹理: cut a piece of wood along/across the grain 把木头顺着{对着}木纹截断

cross-cut

1. (of a saw, etc) with teeth designed for cutting across the grain of wood (锯子等)有为横割木纹而设计的锯齿的
2. 用那样的锯子cut

不是犬牙交错，也不是横七竖八。形容纹理的词语有哪些？

Data logging is a common cross-cutting concern, being used in many other parts of the program other than the particular module(s) that actually log the data. Since changes to the logging code can affect other sections, it could introduce bugs in the operation of the program.

four和for同音，two和to同音。log4是log for java的意思。B2C是Business to Consumer.

A Conceptual Information Model is a high level diagram describing the important information in an enterprise or system; it is typically useful for communicating ideas to a wide range of business and technical stakeholders.
