physical design guide. (1) design mode and submode The Relational Database pattern design can be completed in four steps. ① Establish the initial Relationship Model ② Normalization ③ Model evaluation ④ Correction mode The final mode and sub-mode are determined through multiple mode evaluations and mode revisions.

, and the second part focuses on application implementation. When developers using the object-relational database management system (ordbms) adopt a more "holistic" approach than the typical relational DBMS Technology for database analysis and design, it will benefit the most from ordbms technology.

of responsibility to deal with the request, I believe we are often used. The advantages of this approach are straightforward, straightforward, and easier to maintain, but there are a few more troubling problems with this approach: Code bloat: The decision conditions in the actual application are usually not so simple as to determine whether it is 1 or 2, and may require complex computations. may need to query the

increases, you can upgrade the application server and database server respectively, this deployment method is a typical deployment method for small-scale websites.

With the application of the orm framework, development is more object-oriented, and there is no need to design a database specifically, instead of writing entities and object ing. Therefore, entity writing is a very basic and important task. Do not drag your development work back when you do it. For example, to verify the validity of data, we are used to doing it

partitions:A partition mapping relationship is created for each possible result of the partitioned index field, which is very large and needs to be written to the database.
