In terms of personnel data management, where should personnel data be maintained?

The most effective method for managing personnel data is through centralized databases. Centralized databases allow for more efficient storage, retrieval, and management of personnel information. They provide a secure and organized system that can be easily updated, ensuring that information is current and accessible to authorized personnel. Furthermore, centralized databases facilitate better data analysis and reporting, making it easier for decision-makers to access and interpret data related to personnel management.

Maintaining personnel data on paper records is less efficient and poses risks such as loss, damage, or unauthorized access to sensitive information. Personal files can lead to fragmentation and inconsistencies in data, making it harder to manage and analyze.
