The text explores the fundamental differences and use cases of vector and graph databases, particularly in handling unstructured data alongside large language models (LLMs). It explains that vector databases store high-dimensional numerical embeddings derived from data like text, images, and audio, facilitating efficient similarity searches, while graph databases use nodes and edges to represent complex relationships between entities, making them ideal for queries about interconnected data. Both database types support AI-driven applications, yet they differ in data modeling, query capabilities, and scalability. Use cases highlighted include fraud detection, scientific research, ecommerce, and media, where vector databases excel in similarity searches and graph databases shine in relationship analysis. FalkorDB is introduced as a hybrid solution offering the benefits of both database types, along with tools for building and visualizing knowledge graphs. The text aims to guide developers in selecting the appropriate database technology based on their specific data and application needs.
