What model enables secure searching of several different databases?

1. Centralized Model

2. Federated Model

3. Hierarchical Model

4. Collaborative Model

The correct answer is: Federated Model

The federated model is designed to enable secure and efficient searching across multiple databases. This is achieved by allowing each database to maintain its autonomy while participating in a unified search process. In this model, search queries can be executed across various databases simultaneously, and these databases share their results with the user in a coherent manner. This approach is particularly beneficial in environments where data is distributed across different locations or systems, as it supports interoperability without requiring data to be consolidated into a single repository. The federated model ensures that sensitive information remains secure by not transferring data unnecessarily, thus allowing users to access diverse sources while maintaining compliance with data privacy and security protocols. In contrast, other models like the centralized model have a single point of access, the hierarchical model organizes data in a tree-like structure without the direct capability to search different databases simultaneously, and the collaborative model typically focuses on joint efforts rather than database searching. This clear distinction highlights the appropriateness of the federated model for the scenario provided.
