One of the disadvantages of a centralized metadata structure is:

• A. Always current updates
• B. Simple processing of queries
• C. High costs of repository maintenance
• D. Limited query processing demands

Answer: (C)

A centralized metadata structure has several notable characteristics, and one significant disadvantage is indeed related to the high costs of repository maintenance. In this model, all metadata is stored in a single repository which can entail considerable investment in terms of infrastructure, technology, and the personnel required to manage and maintain the repository effectively. Maintaining a centralized metadata repository often requires ongoing investment in hardware and software updates, system backups, and security measures to protect the sensitive and vital metadata information. Additionally, as the volume of data and metadata grows, the complexity of maintaining this repository increases, which can lead to further costs associated with scaling the system and ensuring it remains performant. This centralized approach might also necessitate hiring specialized staff, thereby increasing operational expenses. In contrast, advantages such as always current updates, simple processing of queries, and limited query processing demands generally highlight the strengths of centralized systems. While these aspects are indeed beneficial, they do not mitigate the financial implications associated with maintaining such a centralized structure. Thus, the high costs of repository maintenance stand out as a critical disadvantage when considering data management strategies.
