When explaining the new features of SQL Server Bi yesterday, I mentioned an enhancement of SQL Server 2008 database engine, namely, Change Data Capture (CDC): Change Data Capture. It seems that everyone is interested in this function, and many people ask questions. Let me sort out the key points. 1. What is the purpose of CDC? CDC is a mechanism that greatly f

Starting with 08, SQL Server provides a feature called change data capture CDC, which enables you to view the changes in the data of the table objects in the database by enabling this feature. (I feel like a bit of a data change function that SQL Server provides directly to the user.)According to the official statement. Using the CDC feature has the following benefits1, this is the database comes with the f

This makes it very inconvenient for many debugging personnel to use the mobile phone. Maybe you can buy a USB to 232 conversion line on the market, but the anti-interference of these lines is not very good, in some places where the interference is large, there will be connection interruption, so it is often necessary to add an optical coupling isolator
