Question

Data must possess some key characteristics. Using the example of Smart Cards or Automatic fare collection elaborate on the following: Reliable, Timely, Complete

Answer 1

Reliable: The data should be accurate, consistent and stable in order to provide data reliability. For the case of fare collection using smart card when the card is inserted the user record should be fetched properly. The fare amount should be deducted from the specific user only. The fare should be calculated without any error.

Timely: The timing should be proper in order to provide timely data. For the case of fare collection using smart card when the card is inserted then only the transaction will be processed and the amount will be charged. The transaction should not be completed long after the transaction initiation. Without proper timing the data will create confusion and will cost the user both time and money.

Complete: The data should be complete and proper in order to provide completeness of data. For the case of fare collection using smart card when the card is inserted the transaction should be completed. The fare amount must be deducted from the proper and correct user only. If the data is incomplete then the transaction will not be completed and it will cost time and money.

Hope this helps.
