What it is

The Machine Learning Database is a specialized database that allows users to store data, explore it using SQL commands, train machine learning models, and expose these models as APIs over a RESTful interface. It's ideal for teams needing an integrated solution for both data storage and model deployment.

MLDB stands out as an open-source, self-hosted solution that integrates data storage with machine learning capabilities through RESTful APIs and SQL support.

When it fits — and when it doesn’t

A good fit for

  • Teams that need an integrated solution for storing, exploring, and deploying machine learning models

  • Developers who prefer a self-hosted, open-source tool with RESTful API capabilities

Look elsewhere if

  • Projects requiring cloud-based managed services without the need to host their own infrastructure

  • Users looking for a graphical user interface (GUI) for database management and model deployment
