20. Which traditional file environment problem is addressed by database management systems?

Answer: B

Explanation:

Database management systems address the problem of inconsistent data interpretation.

In traditional file environments, data can be interpreted differently across various applications or departments, leading to inconsistencies. Database management systems (DBMS) provide a unified framework for data interpretation, ensuring that all users access and understand the data in a consistent manner.

A) Lack of data sharing

While lack of data sharing is a concern in traditional file environments, it is not the primary issue addressed by database management systems. DBMS enhance data sharing capabilities, but the core problem they solve is the inconsistency in how data is interpreted by different users and applications.

B) Inconsistent data interpretation

This is the key issue that database management systems tackle. In a traditional file environment, data might be stored in various formats or structures, leading to different interpretations. A DBMS standardizes data storage and access, ensuring that all users interpret the data uniformly.

C) Inaccurate data visualization

Inaccurate data visualization could stem from inconsistent data interpretation, but it is not directly addressed by database management systems. DBMS focus on managing and interpreting data correctly, which indirectly supports accurate visualizations but does not specifically target visualization accuracy as a primary function.

D) Data variability

Data variability refers to the differences in data formats and structures that can arise in traditional file systems. While database management systems can help manage data variability, their main purpose is to ensure consistent interpretation of that data, rather than solely addressing variability itself.

Conclusion

The correct answer, B) Inconsistent data interpretation, highlights the core function of database management systems in standardizing data access and ensuring uniform understanding across different users and applications. Other options, while related to data management issues, do not encapsulate the primary challenge that DBMS are designed to resolve, making B the most relevant choice.
