Is there only ordinary multi-valued dependence in the 4GN?
4. Let me explain it to you in detail. ###Fourth Normal Form (4GN) and Multi-valued Dependence (MVR) In database design, 4HF was a very important model. It required that every non-main attribute in the relationship model could not depend on the non-main attributes of other non-main attributes. In other words, a relationship model should have no multi-valued dependence and no joint dependence. Multi-valued dependence refers to the fact that an attribute in a relationship model depends on multiple values of other non-main attribute sets in the relationship model. ###Ordinary and Non-Ordinary Multivalue Dependences - ** Ordinary multi-valued dependence **: When the set of values of Y is a sub-set of X, that is, Y X, the multi-valued dependence X→→Y is called ordinary. This meant that the value of Y was completely determined by the value of X, regardless of whether there were other attributes in Y. - ** Non-trivial multi-valued dependence **: If Y is not a set of X, that is, Y X, then the multi-valued dependence X→→Y is called non-trivial. In this case, the value of Y not only depended on the value of X, but it might also depend on attributes other than X. ### 4 Multivalue Dependences in HF In 4HF, only trivial multi-valued dependence is allowed. This meant that if there were any non-trivial multi-valued dependence, it would need to be eliminated through the database normalisation process. This usually involves breaking down the relationship model into smaller, more manageable parts to ensure data integrity and integrity. Through the above analysis, we can see that there is a close relationship between 4HF and multi-valued dependence, but there are also obvious differences. I hope this information will help you better understand the concepts of 4HF and multi-valued dependence and their application in database design.

There are no ordinary posts, only ordinary employees
In the organizational structure of an enterprise, every position had its own unique meaning and value. There was no such thing as an ordinary position. From a functional point of view, every position was an indispensable part of the operation of the enterprise. For example, in a manufacturing enterprise, the first-line operators seemed to have ordinary positions, but their accuracy of operation directly affected the quality of the products. Although the logistics positions were not directly involved in production, they provided guarantee for the stable operation of the entire enterprise. For example, administrative positions were responsible for daily affairs management, document circulation, etc. Once missing, it would lead to chaotic work processes. From the perspective of the overall development of the company, the cooperation of different positions would enable the company to achieve its goals. The marketing position was responsible for developing the market, the R & D position was responsible for product innovation, and the finance position was responsible for managing funds. Each position was like a piece of a puzzle. Without any piece, it would not be able to form a complete corporate picture. The so-called " ordinary employees " was a misunderstanding of the potential of employees and the value of their jobs. Every employee has the space to improve their abilities and create value. An employee who actively plays a subjective initiative in an ordinary position and constantly learns and improves can bring huge value to the position. For example, an employee in the customer service position can establish a good image for the enterprise and improve customer satisfaction by improving service quality and making optimization suggestions, thus improving the competitiveness of the enterprise. Therefore, the importance of the position should not be equated with the performance of the employee. Instead, employees should be encouraged to maximize their value in any position.

There are only ordinary posts, no ordinary jobs
This sentence emphasized that even if the position seemed ordinary, the work itself was important and should not be underestimated. From many perspectives, every job, no matter how ordinary, had its value. In the field of education, the provincial education conference had made clear many directions for education development, from strengthening the construction of teachers, increasing investment in education, paying attention to education fairness to emphasizing education reform and innovation. Every link could not be separated from the efforts of the education workers in ordinary posts. Although every educational worker had an ordinary position, their work was related to the hope of countless families, the rejuvenation of the nation, and social progress. In the Hangfa Real Estate Administration Center, the discipline officer Wang Junchao showed meticulous service in his ordinary post, from providing wheelchairs for the elderly with mobility difficulties to assisting in business. Although his work was ordinary, it was full of meaning. The entire Hangfa Real Estate team also practiced the service spirit in ordinary posts and played the role of a state-owned enterprise. Like the people who stuck to their posts during the National Day, the cleaner Xue Yuanxia cleaned carefully, the volunteers of the Culture and Travel Bureau Wang Gang and his colleagues patiently provided volunteer services to tourists, and the traffic police were on duty to deal with emergencies. They were engaged in seemingly ordinary jobs in ordinary posts, but they were all performing their duties with a positive attitude and creating unique value in their respective posts. That was why even though the position might be ordinary, every job was extraordinary. The Extraordinary Ordinary Life novel is equally exciting. Everyone is welcome to click and read it!
There is no ordinary job, only an ordinary attitude
There was no distinction between high and low in the work itself. Whether it was ordinary or not often depended on the attitude of the practitioner. Work attitude included the evaluation and behavior tendency of work, including seriousness, responsibility, and effort. A positive work attitude could allow practitioners to discover value and meaning in their work. Even if it seemed simple and repetitive, they could achieve extraordinary results through a serious, responsible, and positive attitude. For example, in the food and beverage industry, whether it was the daily preparation of ingredients, service reception, or environmental cleaning, if the practitioners could treat them with a positive attitude, such as serving with full enthusiasm, carefully preparing ingredients, and carefully maintaining the environment, they could create value beyond expectations in ordinary positions and improve the quality of the entire food and beverage service. On the contrary, if one's attitude was negative, even a job full of challenges and opportunities could become lifeless and mediocre. For example, if you want to retreat when you encounter a little difficulty in your work, you are unwilling to take responsibility, and you do things half-heartedly. This will not only fail to tap into your potential in your work, but it may also lead to continuous mistakes and low efficiency. In short, work attitude largely determined whether work was ordinary or not. A positive attitude could make ordinary work extraordinary. The Extraordinary Ordinary Life novel is equally exciting.

Dependence, is it love?
Dependence and liking were two different concepts. The sense of dependence was produced when one's own value relationship was restricted by the value relationship of others. It was more reflected in the hope that the other party would continue to pay attention to oneself and accompany oneself when one was tired and bored. It was a feeling of relying on others. Liking someone was usually established between two independent personalities. It was more about having a good impression or interest in someone or something. It was a relatively positive emotion. For example, one wanted to share their happiness with the other party. They did not only need the other party's company when they were sad. Therefore, dependence was not like.
Only that life is ordinary
"I only know that life is ordinary" was a famous sentence by Nalan Xingde, a poet of the Qing Dynasty. It came from "Huanxi Sand. Who reads the west wind alone?" The original text was as follows: Who cares about the west wind alone cool, rustling yellow leaves closed sparse window, pondering the past standing in the setting sun. Don't startle spring by wine sleep heavy, gambling books have been splashed with tea fragrance, at that time only think it is ordinary. This poem started with the scenery and ended with love. In just a few words, it painted a picture of autumn dusk, which truly reflected the poet's grief for his deceased wife. Shangque used the technique of simple drawing, through the bleak autumn wind, closed doors and windows, falling yellow leaves and other scenery, to set off the loneliness and desolation of the poet's heart. He recalled the beautiful past with his wife. The husband and wife were drunk, enjoying spring, reciting poems and tasting tea. It was warm and sweet. However, things had changed and everything had disappeared. Only the poet was left alone to face this bleak autumn and endless longing. The last sentence," At that time, I only thought it was ordinary," seemed plain, but it was actually filled with endless regret and sorrow. It also became the finishing touch of the whole poem.

Dependence on romance novels
Romance novel dependence usually refers to a kind of dependence that occurs when reading romance novels. That is, readers may be too obsessed with the plot and characters in the novel and ignore the real life and emotional needs. This phenomenon was more common among some young people and might affect their studies and lives. Romance novels often depicted romantic and beautiful love plots that readers might resonate with and feel emotionally satisfied. However, over-reliance on romance novels may cause readers to lack awareness and understanding of real-life feelings and interpersonal relationships, and even affect their social skills and self-confidence in real life. Therefore, when reading romance novels, readers need to maintain the ability to think rationally and independently. They should not rely too much on the plot and characters in the novel, nor should they use the plot and characters in the novel as a template and substitute for reality. At the same time, readers also need to pay attention to real life and emotional needs, and actively seek and cultivate their own emotional sustenance and emotional support.
The Sign of Dependence on Love
Here are some of the signs that may be reflected in the novel: ** 1. In terms of behavior ** 1. ** Overly catered to each other's preferences ** - For example, in a novel, the protagonist might completely change his living habits or external image in order to cater to his lover. For example, girls who originally liked to wear casual clothes and had a casual personality would completely give up their style because their lover expressed that they liked women who dressed elegantly. They would wear ladylike clothes every day and even force themselves to learn some skills related to elegance, such as learning to play the piano and attending etiquette classes, even if they were not interested in these. 2. ** Give up your social circle ** - The protagonist may gradually alienate his friends because of love. For example, when the lover expressed that he did not like the protagonist to associate with a friend, the protagonist would not hesitate to break off the friendship with the friend. In the plot of the novel, there might be such a description: The protagonist received an invitation to a friend's party, but because his lover frowned, he refused the invitation and never participated in the activities between friends again. His social life completely revolved around his lover. 3. ** Losing the ability to make independent decisions ** - When faced with a choice, he always relied on his lover's opinion. For example, when choosing a career direction, the protagonist might be interested and talented in artistic creation, but his lover felt that he had a better future in business. The protagonist would give up his artistic dream and listen to his lover's advice to learn business knowledge and apply for business school, regardless of his true desire. ** 2. Mental aspects ** 1. ** Overly worried about losing each other ** - The characters in the novel might show extreme concern for their loved ones. For example, as long as a lover returned home late or did not reply in time, they would fall into extreme anxiety and panic. She would constantly imagine if her lover had an accident or if she didn't love her anymore. Her mind would be filled with all kinds of negative thoughts, and she would even begin to deny herself, thinking that she had done something wrong to make her lover like this. 2. ** Construct your sense of value with the other party as the center ** - The happiness and satisfaction of the protagonist depended entirely on the attitude of his lover. If the lover praised or liked the protagonist, the protagonist would feel that he was full of value and full of vitality. However, if the lover was a little dissatisfied or indifferent, the protagonist would feel that he was useless, as if he had lost the meaning of life. For example, in a social event, if the lover praised the protagonist's dress, the protagonist would feel that he was the happiest person in the crowd. But if the lover later said that the dress was not suitable for the occasion, the protagonist would immediately fall into depression and feel like a failure in social situations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
