Vector vs. Graph Databases: Choosing the Right Backend for RAG AI

By PulseAugur Editorial · [1 sources] ·

The choice between vector databases and graph databases is critical for optimizing Retrieval-Augmented Generation (RAG) AI applications. Vector databases excel at semantic similarity searches, making them ideal for unstructured data like text and images, and are commonly used with LLMs like GPT for context retrieval. Graph databases, on the other hand, are suited for uncovering intricate relationships within data, making them valuable for applications where connections between entities are paramount, such as knowledge graphs or fraud detection.
