Final answer:
For a video and animation-sharing website anticipating high server loads, an object-relational DBMS is the most appropriate choice due to its capability to manage a diverse range of data including multimedia content, and its blend of relational robustness with object-oriented flexibility.
Step-by-step explanation:
If you are creating a video and animation-sharing website with anticipated high loads on the server, selecting the right Database Management System (DBMS) is crucial. In your case, an object-relational DBMS (Option A) is most likely to serve your needs. Object-relational DBMSs are designed to handle a wide variety of data types including large binary objects like videos and animations. They combine the robustness of relational models with the flexibility of object-oriented programming, which is beneficial for handling multimedia content.
While relational DBMSs (Option B) are well-suited for structured data and complex queries, they might not be as efficient for handling large-sized multimedia files. Hierarchical DBMSs (Option C) follow a tree-like structure and are not flexible for the complex operations a video sharing site may require. Lastly, OODBMS (Option D) - Object-Oriented Database Management Systems are great for storing objects but might not perform as well under very high loads as object-relational DBMSs.
