trivial functional dependence and partial functional dependenceBased on context alone
1. ** Ordinary Function Dependence **
- In a database, let R(U) be a relation pattern on a set of attributes U, and X and Y be a set of attributes U. If Y is a sub-set of X (that is, Y X), then X→Y is a trivial functional dependence.
- For example, in the relationship mode of students (student number, name, gender),{student number, name}→{name} is a trivial functional dependence, because the name itself is a part of {student number, name}. Semantically speaking, trivial functional dependence represented an obviously established dependence relationship. This dependence relationship did not actually contain much meaningful new information, because it only indicated that the dependence of a set of attributes on its own set must exist.
2. ** Part of Function Dependence **
- Let (X,Y) be the property set of the relation pattern (R). If (X→Y) exists a proper set of (X ') such that (X'→Y), then (Y) is partially dependent on (X).
- For example, in the Relational Mode course selection (student number, course number, grades, course name),{student number, course number}→{course name}, but in fact,{course number}→{course name}, which meant that the course name only depended on the student number and the course number in the course number, not the entire {student number, course number}, so the course name was partially dependent on {student number, course number}. Partial functional dependence may cause data redundancy-like problems. In the standardized design of a database, it is usually necessary to eliminate partial functional dependence to achieve a higher standard.

Multi-functional apartmentThere were many key points in the design of a small multi-functional apartment.
First, the spatial layout. Most of them adopted open designs, such as open kitchen, living room, kitchen, dining room, etc., which broke the traditional partition, made the space transparent, improved the overall sense of spaciousness, and allowed sunlight to penetrate freely. For example, some small apartments adopted a horizontal pattern to achieve full functionality through reasonable layout. Extremely small apartments (about 40 - 50 square meters) must first ensure basic sleeping, cooking, dining, and washing space. On this basis, find ways to integrate the multi-functional room with the living room and other spaces. He could also adjust the layout of the room, such as changing the vertical layout of the bathroom to horizontal, using the corner to make a cut to let in natural light, or using a three-dimensional structure to remove excess walls.
Secondly, the choice of furniture. The application of multi-functional furniture was the key, such as storage under the bed, folding tables on the wall, invisible cabinets, etc., which could be used as a living room during the day and a bedroom at night. In the design of the multi-functional room, in addition to the custom-made whole house, movable furniture and finished furniture could be used to create a "growable space" that could cope with the changes in needs at different stages.
Furthermore, the colors and materials matched well. Often choose bright colors and simple furniture, such as bright wood tones or white, to enhance the sense of space and vitality, so that the residents feel more comfortable in a small space.
Finally, in terms of functional integration. The functional rooms of the small multi-functional apartment could take into account a variety of functions, such as storage room, study room, tea room, mobile display, etc. It could also take into account the functions of piano room, studio, cloakroom, etc. according to the needs of different residents. The common tatami + storage cabinet + desk form could make the small room have the functions of study, bedroom, and storage room. There were also many creative designs in the kitchen, bathroom, and other areas. For example, the white floating box in the kitchen contained complete equipment, and the bathroom used dry and wet separation and color to create an atmosphere.

13:"Red Heart Sky Patrol": -[Excellent Series-]--Top 3500 likes next time!
It was a rather exciting Xianxia novel, written by one of the twelve heavenly kings in the year 2022,"Why Do I Feel So Formidable?" Why did this book stand out among so many Xianxia writings? I think there are three reasons.
First, the author's writing skills were outstanding. Not to mention the various exciting plots at the end, many readers would be attracted from the first chapter. The first chapter was about the duel between two masters. The writing was excellent, but the emotional fluctuations were even better. Everyone thought that Zuo Guanglie would burn himself and die with his pursuers, but in the end, he was beheaded with a light sword. This kind of treatment showed the gap between cultivators and was fascinating.
Secondly, the character was attractive. The main character was a tenacious cultivator. No matter what the situation was, he would have the spirit to fight. Moreover, he was not a saint. For example, when he was betrayed by his good brother, he would kill him regardless of what others said. As for the other characters, even if they were villains, they were not brainless. The descriptions of the small characters were also very appropriate and vivid.
Third, excellent control of rhythm. For example, in the opening story, after the protagonist killed his old friend who had betrayed him in a duel, the author did not mention the matter at all. Instead, he described the outcome of the traitor and the sadness of his brother's betrayal through the actions of the protagonist's other brothers. This way, the readers were immersed in the aftertaste of the incident. In the next chapter, there was a sudden change in the situation and a battle scene. It could be said that the control of the rhythm was extremely outstanding.
Overall, this book was worth reading and was highly recommended.

"Who's in Love After Rebirth?""Who's in Love After Rebirth?" was an unforgettable novel. At the beginning of the story, the readers thought that the heroine would pursue the goal of being the richest man in the world, but they did not expect that the heroine would give up so quickly. In the story, the part about his career almost became the background, but this did not affect the overall sweet atmosphere. The way the author handled the two main characters was outstanding, making people envious of their friendship. The writing style of this book was excellent, the plot was smooth, and the author's style was admirable. It was one of the few well-written works. After the readers finished reading, they couldn't help but sigh. This book could be said to be the most popular novel in the world of sweet literature recently, and it was unforgettable. I hope the author can get better and better!
