the SX table and the SY table. If you create a view Student: CREATE VIEW Student（Sno，Sname，Ssex，Sage，Sdept）AS SELECT SX.Sno，SX.Sname，SY.Ssex，SX.Sage，SY.Sdept FROM SX，SY WHERE SX.Sno=SY.Sno；In this way, although the logical structure of the database has changed (to SX and SY tables), the application does not need to be modified because the newly created view is defined as the user's original relationship, keep the user's external mode unchanged, and the user's application can still search for da

Unlike automatic database backup, the system administrator must take certain actions to protect data from unauthorized users. If you are using MySQL, you can use some convenient functions to protect the system and greatly reduce the risk of unauthorized access to confidential data. The most valuable asset of an enterprise is usually the customer or product information in its database. Therefore, unlike automatic database backup, the system administrat

According to a report released today by the ponemon Institute, most companies are actively moving towards cloud computing, even in the absence of effective security protection, transfers confidential or sensitive data to the cloud.The report pointed out that the transfer speed of enterprises to cloud computing far exceeds the carrying capacity of the enterprise's cloud security environment. According to the survey, most respondents said they had uploa

1. Generally when we request resources across domains in Ajax, the browser console will report the following error:Code:$.ajax ({ URL:"http://127.0.0.1:8000/get_data.html", success: Function (response) { alert (response) }})Error:The reason is because, in the response of the cross-domain return value, a header value is missing: Access-control-allow-origin, which causes the browser to intercept .... This is called the browser's homologous policy.At this point, we offer 2 methods.M

A little bit confused about the public key and the private key, search for some information, do some sorting it, first look at this: Encryption--Public keyDecryption--Private keySignature--Private keyAuthentication--Public key Look at this. The private key may be used for signing, in fact, it is equivalent to the private key encryption, and public key authentication is to use the public key decryption, but not for confidential information. Because the

MD5 algorithm is widely used, and almost no algorithm implementation of the vulnerability, you can search through Google to a large number of implementation of the MD5 algorithm of the library, according to document instructions directly called.Of course, the MD5 algorithm also has its shortcomings, because the MD5 is completely irreversible, so a must be constant, once the cracked organization obtained a pair of legitimate u, R, they can trace the legal a, B value, so as to obtain

Views enable users to view the same data in multiple ways The view mechanism enables different users to view the same data in different ways, and this flexibility is necessary when many different kinds of users share the same database. 3.
