Can all redundant information be deleted?

Redundant information refers to the duplication of information caused by the unreasonable design of data structure and storage, and the most common occurrence is in the design of the database.

Redundant information in a general database can be eliminated or reduced by schema decomposition, which may lead to some errors if it is deleted directly.

Is it redundant information found in the optimization master? If so, you can delete it!

It's the optimization master who found out that you can delete it, no problem. Rest assured.

Redundant duplication or verbosity (including information, language, structure, services, software, hardware, and so on) is called redundancy. Redundancy has two meanings, the first meaning refers to the redundant unwanted part, and the second meaning refers to the artificial increase of duplicate parts, the purpose of which is to be used to back up the original single part, in order to enhance its security, which has a wide range of applications in information and communication systems.

Redundancy means: redundant repetitive or verbose content (including information, language, knowledge, etc.).

Chinese language disorders. In Chinese language disease, the colloquial term for redundancy is "redundant ingredients". There are two cases of redundant ingredients:

One is that there are redundant elements in the sentence, but the meaning is still clearly expressed, for example: there are old masters, young young apprentices. With "young", there is no need to say "young". This is what is commonly referred to as repetition.

The other is that there are some elements in the sentence that cannot be there at all, so the meaning is not clear and difficult to understand. This redundancy is divided into redundant subject components, redundant predicate components, redundant object components, redundant definite components, adverbial redundancy, complement redundancy, etc.

Data redundancy. Data redundancy in a database roughly means duplicate data and wastes space.

For example, if there are two tables in a database, and one table has a field to store a person's **, if ** is stored again in the second table, it is a typical data redundancy. In fact, when we describe an object, the object has many properties.

When you use a database to store these attributes, you should put them appropriately in a specific table in the database. If the table is designed, the data redundancy and change will be small.

For example, if you describe a student's attributes, there are some basic information and grade information, etc., so that the basic information and grade information should be divided into two tables and stored separately, otherwise when you view the basic information and information, the grade information will be redundant, affecting performance and wasting time.

Redundancy refers to the redundant or repetitive part of the speculation that is more than is actually necessary or reasonable.

In all areas, redundancy represents a wasteful or unnecessary existence. Redundancy can refer to redundancy in matter or information. On the material side, redundancy usually refers to the presence of extra parts or resources in a product or system that exceeds the actual need.

For example, in a production process, too many spare parts, materials, or equipment can lead to wasted resources and increased costs.

In terms of information, redundancy can refer to the duplication, lengthiness, or unnecessary content of data or information, placing an additional burden on storage, transmission, and processing. Redundancy can also refer to duplication or redundancy in an organization or work.

In terms of organization, redundancy usually refers to duplication of people or responsibilities. When a job or responsibility is taken on by multiple people or departments, it can lead to inefficiencies, wasted resources, and chaotic decision-making. Because of this, in organizational design, a reasonable division of labor and clear responsibilities can effectively avoid redundancy.

The history of the word redundancy can be traced back to ancient Chinese. In ancient Chinese, redundant means redundant and complicated, while surplus means more than necessary. These two words come together to form the word redundancy.

In ancient times, people often used words to express different concepts and meanings. The combination of redundancy and redundancy is called redundancy, which is used to refer to the redundant or repetitive part that is more than is actually needed. The word has been preserved in the Chinese language and is widely used in modern languages.

The term redundancy has also been borrowed and translated into other languages. In English, redundancy is often translated as redundancy, in French it is redondance, in German it is redundanz, in Japanese it is verbose, etc.

Redundancy is the meaning of redundant repetition or wordiness. Redundancy has two meanings, the first meaning refers to the redundant unwanted part, and the second meaning refers to the artificial increase of duplicate parts, the purpose of which is to be used to back up the original single part, in order to enhance its security, which has a wide range of applications in information and communication systems.

Redundancy is the meaning of redundant repetition or wordiness. Redundancy has two meanings, the first meaning refers to the part that is needed to make the pants of the redundant non-celery, and the second meaning refers to the artificial increase of the duplicate part, the purpose of which is to use Hu Song to back up a single part of the original simplified version, so as to achieve the purpose of enhancing its security, which has a wide range of applications in the information and communication system.

Dear, here is the information for you to expand: **redundancy, that is, unnecessary ** paragraphs when programming. Generally speaking, a program can perform the established task, but after optimization, it can also achieve the purpose, the execution efficiency is stronger, and the number of ** is reduced, indicating that the ** deleted ** is the redundancy of the program**.

Redundancy is divided into two parts: redundant execution and quantity redundancy. For example, in the function of a certain program, the statement that appears has no effect on the returned parameters in the call, but is executed many times, it is redundant, this redundancy is the consumption of CPU, this redundancy should be eliminated, and it should be commented out.

The main thing is that there are too many comments in **, or some unused variables and functions in the program, and this redundancy will make ** less readable.

Redundant duplication or verbosity (including information, language, structure, services, software, hardware, etc.) is called redundancy.

Redundancy has two meanings, the first meaning refers to the redundant unwanted part, and the second meaning refers to the artificially increased duplication of the part, the purpose of which is to be used to back up the original single part, in order to enhance its security, which has a wide range of applications in information and communication systems.

Redundancy is a Chinese word, pinyin is rǒngyú, and in English it is redundancyredundance.
