A Property Graph is a data structure used to represent and store information in a way that highlights relationships between different entities. In this model, data is organized into nodes (which represent entities like people, places, or products) and edges (which represent the relationships between these entities). Each node and edge can have associated properties, which are key-value pairs that provide additional information, such as a person's age or the weight of a product. This structure is particularly useful in applications like social networks, recommendation systems, and fraud detection, where understanding the connections and attributes of entities is crucial. By using a Property Graph, developers can efficiently query and analyze complex relationships, making it easier to derive insights from interconnected data.
