Native SQL query : it means querying directly using standard SQL statements or SQL for a particular database. The control of the native SQL query execution is done through
the CPU, so the CPU is a computer's soul and core. And the response CPU speed of the basis is the frequency, the higher the frequency, the CPU processing data faster. And the core frequency is when starting a running program, the processor will automatically accelerate to the appropriate frequency, and the original speed will enhance the 10%~20% to ensure the smooth operation of a program of technology. Here is the latest CPU performance ladder chart, and you can choose the CPU you want based o
