Parse:
data coupling: A set of modules passing simple data with the help of parameter tables .
public coupling: Multiple modules all access the same common data environment .
external coupling: A group of modules all access the same global simple variable, and the information of the global variable is not passed through the parameter table .
content coupling: One module directly accesses the internal data of another module ; one module does not go through the normal entry to the inside of the other module ; some program codes of the two modules overlap ; one module has multiple entries .
