About the theoretical knowledge of database design, small part of the temporary introduction to here, next, we take a look at the past years of soft test real problem, see how we use theoretical knowledge in the actual use of the NIE? Analysis of typical examplesFirst, let's take a look at a November 2004 real topic, a

A successful management system is made up of: [50% of the Business + 50% software], and 50% of the success of the software has [25% database + 25% of the program], the database design is a good or bad is a key. The database design is the most important part of the applicatio

Introduction: I have been engaged in database development and design, and I have read some books. A long time ago, I wanted to sort out and summarize the relational database design. However, for various reasons, I was too late to start the work, mainly due to inertia. Today,

functions of the original user can be changed accordingly. Of course, this architecture design moves the function determination of the database management software to the front-end, making the front-end development more complex. However, when the number of users is large (more than 10) or the probability of software upgrade is high in the future, this price is worthwhile. Iv. Simple Batch m: n DesignWhen w

way, the original multi-to-many relationship is now two one-to-many relationships. The attributes of the original two entities should be reasonably allocated to the three entities. The third entity here is essentially a complex relationship, which corresponds to a basic table. Generally, database design tools cannot identify many-to-many relationships, but can process many-to-many relationships. [Example 3
