Sometimes it is necessary to optimize the configuration of the operating system. Just like you optimize your computer settings; Environment classification: The operating job function email list environment also needs to distinguish between dev (development), test (test), product (production) and other environments; more rigorous and pre-release environments (using the data job function email list of the production environment, but the code has not been released to the production environment ),
Grayscale environment (can be seen by a small job function email list group of people) environment, etc.; Table building: Design the database table structure to store data according to the needs of business logic, which is mainly the work of back-end development, and may also be the work of DBA; Write to death: It means that the parameters or configuration contents are job function email list hard -coded, which means that these contents are to be written in the code, and the code needs to be republished for modification.
It saves the time of building tables and writing job function email list interfaces; The advant age of writing to death is that the development efficiency is high, and the disadvantage is job function email list that it is inconvenient to modify, and the version needs to be re-released; 2. What information does the developer say "can't do"? The existing technology cannot be realized at all, that is, it is often said that it exceeds the technical boundary, for example, if you want the download speed to reach 10G/s
