GDB, or Graph Database, is a type of database designed to store and manage data in a graph format. This structure allows for the representation of complex relationships between data points, making it easier to visualize and query interconnected information. Unlike traditional databases that use tables, GDBs use nodes, edges, and properties to represent and store data. GDBs are particularly useful for applications that require deep relationship analysis, such as social networks, recommendation systems, and fraud detection. By leveraging graph theory, GDBs can efficiently handle queries that involve traversing relationships, providing faster insights into data connections compared to relational databases.
