Editor to share with you the database design process does not include which designs, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's take a look at it!

Database design process does not include algorithm design, database design process mainly includes requirement analysis, conceptual structure design, logical structure analysis, database physical design, database implementation, database operation and maintenance stage.

This article operating environment: Windows7 system, Dell G3 computer.

The database design process does not include algorithm design.

The process of database design mainly includes requirement analysis, conceptual structure design, logical structure analysis, database physical design, database implementation, database operation and maintenance.

Introduction to database design:

Database design (Database Design) refers to the construction of an optimal database schema and the establishment of a database and its application system for a given application environment, so that it can effectively store data and meet the application needs of various users (information requirements and processing requirements). In the field of database, all kinds of systems that use database are often referred to as database application system.

The design content of database design includes: requirement analysis, conceptual structure design, logical structure design, physical structure design, database implementation and database operation and maintenance.

Design principle

1. One-to-one design principles

In the process of software development, it is necessary to follow the one-to-one relationship design principle to carry out data maintenance work. By using this principle, we can minimize the occurrence of maintenance problems, ensure the smooth development of data maintenance work and reduce the difficulty of maintenance work. In this process, try to avoid the phenomenon of large data and miscellaneous data, otherwise it will not only affect the progress of software development, but also increase the difficulty of work and affect the quality of its products. Therefore, the design staff must pay attention to this problem. At the same time, fully understand the inevitable relationship between entities, and then achieve the goal of decentralized information and data, and on this basis to improve the overall work efficiency of staff, improve the reliability, science, security and self-performance of software applications.

2. Unique naming principle

The application of the unique naming principle is to reduce the phenomenon of repeated naming and standard naming in the process of database design. Through the application of this principle, we can reduce data redundancy, maintain data consistency, and maintain the corresponding relationship between keywords. The unique naming principle can exercise the staff's proficiency in the operation of uppercase and lowercase letters, which is conducive to the development of standardized background code work.

3. The principle of two-way use

The principle of two-way use includes the principle of transaction use and the principle of index function. First of all, the two-way use principle realizes its form of expression on the basis of logical work unit mode, which not only provides basic guarantee for non-transactional unit operation, but also ensures that it can update and obtain data resources in time. The effective use of the principle of indexing function makes it obtain more attribute column data information and sort it flexibly. At present, the common index modes in the software market are: multi-row retrieval clustered index and single-row retrieval non-clustered index.

The above is all the contents of the article "which designs are not included in the database design process". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
