What is DolphinDB?
DolphinDB is a distributed time-series database and stream processing platform used mainly for financial and industrial analytics. Its AI layer adds natural-language querying, RAG-based knowledge search, agents for stock research and an MCP interface for LLMs.
The core engine stores and queries very large time-series datasets and runs the same factor and indicator logic on both live streams and historical data. It ships with more than 2,000 functions and a SQL-compatible scripting language with Python-like syntax, and can run Monte Carlo simulations and genetic programming in the database with GPU acceleration.
On the AI side, chat-to-query turns plain-language questions into SQL, native MCP support lets LLMs query the database directly, and models can be loaded for in-database inference. The DolphinMind assistant answers questions and generates code for developers.
