[Introduction] Any term that has been designed for databases, as long as it is not a newbie and has heard the word paradigm, the terms 1NF, 2NF, 3NF, and BCNF will pop up immediately in my mind, but if you want to describe the professional definitions of these things in detail ...... Well, at least most people will be dizzy about functional dependencies and function dependencies ,~! @ # ￥ % ...... * [Introduction] Any term that has been designed for d

Label:1. Why do you want to learn the database "paradigm"?When we are independent to complete a small project of their own, we must design the "appropriate" data model is the logical architecture, then, how do we know that our design data model is the most "appropriate"? There must be a standard to measure the data model of their design, see here, you know why to learn the paradigm.2. What problems can the

Standardization refers to the process of removing redundancy from your data storage. If the database design is fully standardized, when all the tables are connected by keywords, no data repetition will appear ). The advantage of standardization is obvious. It avoids data redundancy and naturally saves space. It also provides a fundamental guarantee for data consistency, this eliminates data inconsistency and increases efficiency. 1nf;First NormalForm) The first

Currently, the mainstream databases we use are relational databases, so I am recording some understanding and views on the paradigm in relational databases. Database paradigm is divided into six types (in fact there is a BCNF), from the first paradigm to the sixth paradigm. The high-level layer is based on all the lowe

Find some information on the Internet, record the following and add your own understanding. When designing the relational database, we should design a reasonable relational database to conform to different specifications, and the different norm requirements are called different paradigms, and the higher paradigm database redundancy is lower.
