Differences Between Knowledge Graphs and Vector Databases

🔍**Knowledge Graphs** — Represent data as a network of nodes (entities) and edges (relationships), capturing complex relationships and dependencies. They are ideal for structured data and nuanced queries.
⚡**Vector Databases** — Store and manage unstructured data (text, images, audio) as high-dimensional vector embeddings, enabling fast and efficient similarity searches. Best for applications requiring immediate data retrieval.
📊**Use Cases for Knowledge Graphs** — Suitable for scenarios needing context-rich, explainable answers, such as financial analysis, enterprise applications, and complex data structuring.
🚀**Use Cases for Vector Databases** — Ideal for applications like customer service chatbots and product recommendation engines, where speed and handling large volumes of data are crucial.
💡**Key Differences** — Knowledge graphs excel in handling complex queries and providing explainability, while vector databases are faster and more efficient for similarity searches but may struggle with complex relationships.
