Hello everyone, welcome back to Performance tuning training . Last week we discussed some of the problems in the cardinality calculation process in SQL Server. Today we continue with a detailed discussion of the new cardinality calculations introduced in SQL Server 2014.New

party training institutions have not been able to provide any training on Oracle databases. Oracle sum the entire UNIX world is an attitude that makes it difficult for the outside world to get the information they hold. People who are fortunate enough to use some of these resources tell us that even if you can get the information, it is very difficult to find the information you need. You don't have that m

over.After building the mining structure we can deploy it to the SSAS server, and then look at the accuracy of the algorithm for the current mining model, the exact rate of the mining model we built in this example is only 16.67% very low, and one important reason is that we are using too little data for data training. This number can be significantly improved after the amount of data trained is increased.

Through the training samples of learning, to effectively classify. is to generate the central concept of training samples by training the attribute relationships in the sample, and to predict the unclassified data objects with these already gener

Project Team Project planning should define important tasks, but it takes time to educate team members and weigh expected goals against existing projects. Teams must include: Project supporters, project managers, database administrators, developers, network administrators, testers, and users. In the early stages of the project, be sure not to ignore any teams. Even if team members

network connections, but Windows 2000 provides such a security mechanism. You can use the operating system's own IPSec to implement the security of IP packets. Restrict IP connections to ensure that only the IP address can be accessed, and deny port connections from other IP addresses to effectively control security threats on the network. For Ipsec usage, see: http://www.microsoft.com/china/technet/security/ipsecloc.asp Some of the SQL

Restrictions on network connections The SQL Server 2000 database system itself does not provide a secure solution for network connectivity, but Windows 2000 provides such security. The security of IP packets can be achieved by using the operating system's own IPSec. Limit the IP connection to ensure that your IP is accessible and that other IP ports are connected, and that security threats from the networ

the port used by TCP/IP On the basis of the previous configuration, change the original default port 1433. Select the properties of the TCP/IP protocol in the network configuration in the instance properties to change the default port used by TCP/IP to a different port. 9. Reject probes from 1434 ports Because 1434-port probes are not limited, can be detected by others to some database information, but also may be a Dos attack to the database server
