Which kind of database corresponds to 'graph'?Select one:a.Networkb.Relationalc.Hierarchicald.Object-oriented

Break Down the Problem

1. Identify the characteristics of a graph database.
2. Examine the options provided: Network, Relational, Hierarchical, Object-oriented.

Relevant Concepts

• Graph Database: A database designed to treat the relationships between data as equally important to the data itself. It uses graph structures (nodes, edges) to represent and store data.
• Network Database: Similar to a graph but focuses more on navigable relationships.
• Relational Database: Uses tables and relationships based on foreign keys.
• Hierarchical Database: Organizes data in a tree-like structure.
• Object-oriented Database: Stores data in objects, similar to object-oriented programming.

Analysis and Detail

1. The key feature of a graph database is its ability to model complex relationships using nodes and edges, making it optimal for traversing connections between data points.
2. Among the given options:
   • Network databases can be somewhat related but are not structured as clearly as a graph.
   • Relational databases focus on tables and do not emphasize connections the way graph databases do.
   • Hierarchical databases organize data in a parent-child manner, which differs from a typical graph structure.
   • Object-oriented databases model data as objects but do not inherently focus on relationships like graph databases.

Verify and Summarize

Given the nature of graph databases and the analysis above, we conclude that while the Network database shares some characteristics with graph databases, it is not the direct answer.

Final Answer

The correct answer is: a. Network.
