because, because these columns have very few values, such as the gender column of the personnel table, in the results of the query, the data rows of the result set occupy a large proportion of the data rows in the table, that is, the data rows that need to be searched in the table are large. Increase the index,Does not significantly speed up the retrieval. (3) For those columns that are defined as text, the image and bit data types should not increase the index. This is because the amount of da

The advantages of normalization: Normalization of update operations is usually faster than inverse normalization. When the data is well normalized, there is little or no duplication, so you only need to modify less data. A normalized table is usually smaller and better placed in memory, so it is faster to perform the operation. There is little extra data that means fewer distinct or group by statements are needed to retrieve list

processNodejs encountered I/O event will create a thread to execute, and then the main thread will continue to execute, therefore, take the action of profile to trigger an I/O event, will immediately execute the action of taking timeline, two actions parallel execution, if each need 1S, then the total time is 1S. After their I/O operations are completed, an event, profile, and timeline are emitted, and the event agent receives and continues to perform the subsequent logic, which is the feature

In the design of the database, there are paradigms and anti-paradigm of stress, summarized below. Advantages of the paradigm:1) The normalized database is updated more quickly;2) After normalization, only a small number of duplicate data, only need to modify less data;3) The normalized table is smaller and can be executed in memory;4) Less redundant data, requiring fewer distinct or group by statements when querying.
