You are part of a team writing a system which keeps track of envelopes people send through the postal system. The process begins when a person gives the envelope to a post office, at which point a barcode (containing all necessary information) is generated, and the envelope is labelled. Then, it is possible to keep track of the envelope between different cities/offices. The software has the following functions: i. generateBarcode() ii. createDatabaseRecord() iii. updateDatabaseRecord() iv. decodeBarcodeAndUpdateEnvelopPosition() v. getEnvelopPosition() (a) State and describe TWO types of beneficial module couplings that may be present in this piece of software. (b) For each function, pick an example of possible module cohesion and explain the type of that module cohesion. (c) We know that function updateDatabaseRecord() alters the actions of function createDatabaseRecord(). State and describe the type of module coupling that exists in the code containing these two functions.

(b) For each function, pick an example of possible module cohesion and explain the type
of that module cohesion.
(c) We know that function updateDatabaseRecord() alters the actions of function
createDatabaseRecord(). State and describe the type of module coupling that exists in
the code containing these two functions.
