This article provides only one programming idea, and the Code provided is for reference only. If you need to use it, please complete it yourself.We often need to process user input when making programs. as the main language of Chinese, full-width and half-width problems often occur, which will cause us a lot of trouble during query.This article uses an extension method to solve the problem of full-width switching,The Code is as follows:Public static void Example (string userInput){String

However, in the context of the adjustment to the configur

experts are going to study the so-called transaction isolation level. In fact, the definition of these four levels is to solve the problem caused by the high concurrency of data, then what are the problems? Dirty Read (dirty reading) unrepeatable Read (non-repeatable) Phantom Read (Phantom Read) First look at "dirty reading", see "dirty" the word, I think of nausea, dirty. How can data be dirty? In fact, we often say "junk data". For example, there are two transactions, wh

of this data. If the B transaction is rolled back, then the data read by a transaction is not recognized at all. Look at the cash-for-money transaction and the dirty read scene that was raised when the transfer transaction concurrency: Time Transfer Transaction A Withdrawal Service B T1 Start a transaction T2 Start a transaction T3 Inquiry account balance is 1000 yuan T4 Take out 500 yuan

understand the problems that are associated with transaction concurrency.In general, there are three types of data read problems and data update issues.Dirty ReadAn uncommitted data dependency occurs when a transaction is being modified on one record, but not committed, and another transaction reads the dirty data and processes it further.To give an example: time Transfer transaction a withdraw transaction B T1 start transac

Step 6 BOLT1 submits the ACK value of t1^t3^t4^t5 to the Acker Bolt when the ACK () method is called.None of the bolts in steps 5 and 7 produce new messages, so ACK () commits the ACK values of T2 and t3^t4^t5 to Acker Bolt respectively.In summary, the spout generated by the tuple tree corresponding to the ACK value of the operation is T1^T2^T1^T3^T

the so-called transaction isolation level. In fact, the four levels are defined to solve the problems caused by high concurrency of data. What are the problems? First, let's look at "Dirty reading". When I see the word "dirty", I think of disgusting and dirty. How can the data be dirty? This is what we often call "junk data. For example, two transactions are executed concurrently (that is, competition ). Take a look at the following table and you will understand what I'm talking about:

The cause is caused by a problem on csdn. (See http://topic.csdn.net/u/20071006/18/b5c31f64-ff1f-4f55-9caf-f3c680a469c7.html?
