No, I do not agree with the statement said by ‘system analyst’ that maintaining source documents are unnecessary and the given input data should be directly fed into the computer. One can consider various scenarios of source documents which plays a vital role in data access.
Suppose, a person faces an issue in entering data which does not have direct access or he/she is not comfortable with system or he/she may want thorough check of data.
So it arise a need to maintain data manually as well as fed into the computer system which will help us in future references.
After all the data which is maintained is ultimately for the users interaction to be used easily and effectively by him without any problems and ‘system analyst’ should ensure that it is implemented in a well-defined manner.
