Graph Databases for Generative AI
Graph databases have become a common starting point for generative AI applications, where large language models (LLMs) are used to talk to data. These databases allow users to store embeddings generated by LLMs in a vector database, enabling similarity searches. While vector databases are popular for their simplicity, graph databases offer the advantage of explicit relationships, which provide more accurate results. Combining the capabilities of both databases can enable a wide range of use cases, making them more relevant and accurate for enterprises.
Analytic Databases for Medium-Sized Data
Analytic databases like DuckDB are gaining popularity for their ability to handle medium-sized data workloads efficiently. These databases focus on analytics and optimization for online analytical processing (OLAP) workloads. They offer a low-cost storage system and allow users to run different query engines on the same data, providing flexibility and enabling interactive experiences for analysts and developers.
The Power of Lake Houses
Lake houses, like the concept of the Delta Lake, provide a vision for storing and processing large amounts of data in a cost-effective manner. They enable running different workloads on the same data, offering capabilities like SQL querying, Spark analytics, and machine learning on a single storage system. Lake houses also bring benefits such as data cataloging, governance, security, and orchestration, providing complete visibility and management for multimodal data.
Expanding the Potential of Knowledge Graphs
Knowledge graphs offer a powerful way to represent and traverse complex relationships in data. By using explicit relationships, these graphs provide accurate results and enable a wide range of use cases. While getting started with knowledge graphs may have a learning curve, efforts are being made to simplify the process and provide open-source tools to make them more accessible. Integrating knowledge graphs with AI frameworks like Languagemodels and improving tooling will further enhance their capabilities and ease of use.
