Final answer:
The table exhibits serious data redundancy problems due to the duplication of information within each row. This redundancy leads to inefficiency in storage and can cause difficulties in data management and updating.
Step-by-step explanation:
Redundancy Problems in the Given File Structure
The table exhibits serious data redundancy problems due to the duplication of information within each table. Each row in the table represents a different subtopic, but the same data is repeated in multiple rows. This redundancy leads to inefficiency in storage and can cause difficulties in data management and updating.
For example, in the given table, the 'Subtopic' column has duplicate entries for 'Advantages' and 'Disadvantages'. Instead of repeating this information for each subtopic, it could be grouped differently by having a separate table for 'Advantages' and 'Disadvantages' with columns representing different subtopics. This would eliminate redundancy and make the data structure more efficient.
Redundancy problems in the file structure can also make it more challenging to maintain consistency and accuracy in the data. If the same information is stored in multiple places, any updates or changes need to be made in all instances, which can be prone to errors.
