Some comments about the research, those with evidence, and those with the research have all seen the completion of the ccnp. Here I want to say a few words to my friends. I am a network administrator. After MCSE + ccnp, I have long wanted to post this post, but I have never had time to sort it out, because during the time of chrysanthemum, I have seen a lot of questions and opinions on the certificate, and

Now, what if you want to export a report that shows the data that is confusing to the user as a different entity?One solution is to move the data completely to another main table and then reference it through a foreign key. In the chart below you can see how we created a primary table called "standards" (course level), and then used the simple foreign key to connect to the p

One solution is to completely move the data to another primary table and reference it with a foreign key. In the following chart, you can see how we create a master table named "Standards" course level), and then connect it with a simple foreign key.

the original table uses the data as a reference. You can see that I have created a new table named "Standards" and connected the two tables with a foreign key.
Criterion 5: Be careful with the data separated by delimiters
The second article of the first paradigm stipulates that there cannot be multiple values in one position. Is an example of storing multiple values. After carefully observing the "Syllabus" field, we will find that we have inserted t

Compared to my college syllabus according to Xin Zou Teacher's outline set requirements, our school syllabus may need to make adjustments, what are the possible advantages or disadvantages?By comparing the two syllabus, I found that Xin Z
The System Architect exam is tested once a year, in the second half of the test. As soon as the second half of 2016 is ready, candidates preparing for the System architect exam are now ready to begin. The following is a more professional and more suitable test material for the system architect for exam preparation.Tutorial Classes(1) "System Architect" exam Guide (2nd edition)The System Architect Examination Guide (2nd edition) is the designated reference book for computer technology and softwar
what a "repeating group" looks like. If you look closely at the syllabus (course) field, you will find that there are too many data in this field. Like these fields are called "repeating groups." If we have to use this data again, then these queries will be very complex and I suspect that these queries will have performance problems.
These data columns that are stuffed with delimiters require special attention, and a better approach is to move the f
repeating groups. One of the examples of repeating groups is explained in the below diagram. If you see the Syllabus field closely, in one field we have too much data stuffed. These kinds of fields is termed as "repeating groups". If we have to manipulate this data, the query would is complex and also I doubt about the performance of the queries.These kinds of columns which has data stuffed with separators need special attention and a better approach
