Question

What problems could occur if a database that maintains financial data (such as a credit card database) has incorrect data?

Answer 1

Explanation:

If a database isn't retained then there may be major issues. If student information is in the database and records are not entered accurately the following issues that arise.

• The unwanted spaces will increased in the database.
• The problem of Data Redundancy will occur.
• The problem of misapprehension related to the following data.

If the students entered for a class and the database is not changed, they can appear but are not officially enrolled. Therefore, they will apply for that class, but if the data is updated wrongly, the program may have it in another class.
