user disconnects (the 11th to 20th connection), The connection will not be released immediately, but it will need to wait 10000 milliseconds (the maximum wait time) before it is released and 10 connections remain in the connection pool when no user is connected. In development, the connection pool fatigue error occurs when you use a connection pool without closing the connection (the Close method that invo

Data Mining (DW) is a very important part of business intelligence (BI) all week. What is the data mining in the end, this article will explore this. People often encounter this situation in their daily lives: supermarket operators want to be often bought together by the go

I remember that when I took the postgraduate entrance exam, my professional courses were data structures and C ++. In order to prepare for the exam, I found the classic data structure teaching material of teacher Yan Yumin, I used C ++ to implement all the algorithms mentioned above. Unfortunately, my blog didn't become so popular today. Otherwise, I could write some experiences like guojing.In the evening,

There is a huge amount of data generated every day in life, so what is the use of so much data? In the big data age, the deep combination of big data and cloud computing will have more

I have been chatting with several people recently and everyone has their own views on being active. In addition, many people who are unfamiliar with terms of analysis due to some standard issues have mixed up a lot of information such as being active and retaining. later I found that this is a very real problem.
