Explanation of Ordinary Function Dependence Noun
In a relation, let the relation be R(U), and X and Y be a set of attributes on U. If X contains Y, then there must be X→ Y, which is called trivial functional dependence. For example, in employee relationships, the employee number could always determine itself (recorded as "employee number → employee number"), and the attribute set composed of employee number and gender could always determine the employee number or gender attribute (can be recorded as "(employee number, gender) → employee number" and "(employee number, gender) → gender" respectively). These were all trivial functional dependence. Simply put, one attribute (or set of attributes) was completely dependent on another attribute (or set of attributes). This dependence was obvious and direct. The Extraordinary Ordinary Life novel is equally exciting. Everyone is welcome to click and read it!
Ordinary Dependence and Extraordinary Dependence
Ordinary dependence refers to the dependence of a certain attribute set on itself in the relationship. For example, in a set composed of attributes A and B, the dependence of A and B on themselves (A→A and B→B) is trivial dependence. In a table that stores student performance information, the set of attributes {SNo, CNo, Score},{SNo} → SNo,{CNo, Score} → Score, etc. are also trivial dependence. Nontrivial dependence is if X → Y holds and Y does not belong to X. For example, in a student's report card,{SNo, CNo} → Score is a non-trivial dependence because Score does not belong to the combination key {SNo, CNo}.

Is ordinary dependence the same as extraordinary dependence?
Ordinary dependence was different from extraordinary dependence. A trivial dependence refers to a property or property set that is completely dependent on itself. For example, in the relationship R(A, B), A -> A and B -> B are trivial dependence. The non-ordinary dependence was not the dependence of this attribute collection on oneself. In the process of database normalisation, trivial dependence had no practical effect and would not affect the integrity or integrity of the database design. It was more used to define and identify more complex dependence relationships, such as functional dependence, partial dependence, and transitive dependence. Non-trivial dependence had different effects and meanings in the design of the database. The Extraordinary Ordinary Life novel is equally exciting. Everyone is welcome to click and read it!
The difference between ordinary dependence and extraordinary dependence
Ordinary Dependence referred to the fact that a certain attribute in the attribute set depended on itself and did not need to obtain information from other attributes. For example, in a table containing the property set {SNo, CNo, Score},{SNo} → SNo, {CNo, Score} → Score is a trivial dependence. A non-trivial dependence is a non-trivial dependence if X → Y is true and Y does not belong to X. For example, in the student report,{SNo, CNo} → Score is a non-trivial dependence, because the score Score does not belong to the combination key {SNo, CNo}. In summary, the main difference between the two was that ordinary dependence was the dependence of attributes on themselves, while non-ordinary dependence was the dependence of an attribute (set) on another attribute (set) that did not belong to itself.

A detailed explanation of functional dependence
A functional dependence was a term derived from mathematics. When a set of attributes determined another set of attributes, the other set of attributes depended on the set of attributes. It represents the dependence of the value of one attribute or set of attributes on the value of another attribute or set of attributes. This dependence is the semantical property of the information expressed by the relationship itself, and cannot be determined by the way the attributes form the relationship, nor can it be determined by the current content of the relationship. For example, in a complete functional dependence, if a non-main attribute data item depended on all keywords in a relationship, it was called a complete functional dependence.
