Database redundancy fields and suitability, database redundancy Fields
In my personal opinion, a redundant field is a field that exists in one table and also appears in another table.
For example, there are three tables: User table, product table, and order table. The user table has a field name, and the order table also has a field name.
Good or bad for this field R

Cyclic Redundancy check Cyclic Redundancy test is a set of verification codes based on data computing. It is used to check whether the data is changed or transmitted incorrectly during transmission.Algorithm principle
Assume that 15-bit binary information G = 101001110100001 needs to be sent during data transmission. The binary code can be expressed as an algebraic polynomial g (x) = x ^ 14 + x ^ 12 + x ^ 9
Background:With the information office becoming more and more popular, people's office relies on the Internet more and more, it, the network in the enterprise's influence is more and more big. Therefore, the reliability of the enterprise network becomes very important. For an internet company or a company that needs to use a network to work properly, a broken network means that employees cannot work properly and the company has a lot of money to lose. In such a context, large companies and the f
Meaning and purpose of data redundancyAfter digitizing video and audio signals, the volume of data is staggering, so storing large amounts of image and audio information needs to greatly improve the storage capacity of the system, usually by using a large disk or disc, but this is just one way to solve mass storage, and the role of data redundancy is to save additional data or data on a separate hard disk, to prevent data loss, the following explanati
Source: http://www.itechzero.com/dns-hijacking-dns-pollution-introduction-and-public-dns-recommend.htmlWe know that some network operators for some purposes, some of the DNS operation, resulting in the use of the ISP's normal Internet settings cannot obtain the correct IP address through the domain name. Common means a
Abstract:For the PC104 SCM/deth dual-port ethernet card, an intelligent dual-redundancy Network Driver Based on the Vxworks system is designed, the driver provides functions such as network communication fault diagnosis and intelligent switching between NICs. By testing the performance of the smart dual-redundancy driver, the correctness and effectiveness of the design are verified.Keywords:VxWorks operatin
With the gradual improvement of Ethernet stability, anti-interference and bandwidth problems, Ethernet is entering the industrial control field on a large scale. It is used in industrial process control, communication, spacecraft and navigation systems, and has extremely high requirements on the high speed of reliability and fault response. Currently, redundancy design has been widely used as an effective method to improve the reliabili
HypothesisThere is a "Reader table", and the table has a "borrow Certificate Status" field. This field should be set to "normal", "Report loss", or "cancel account", as shown in the following table:

What should I do if "redundancy" is used to prevent chain loss ?,
Murphy, the strongest man in history, once said: anything that may go wrong will surely go wrong!
So we are used to preparing various "redundancy" mechanisms to prevent the chain from dropping off at critical moments.

Designing and developing a distributed server-side program that can control the client is a blessing and can be done with a lot of things to the client, and it can be done elegantly. The role determines the fate, in the Internet architecture, the Web server must be charged before, destined to the multi-browser version and protocol compatibility with painstaking efforts. But if the Web server is backend, it will be much better, can let the service-side program to isolate, distributed features are
