Overview

Legend Query is a platform component that provides for interactive data exploration. Using Legend Query, data producers expose datasets for consumption by data consumers. Data consumers can use the Legend Pure language in the Legend Query UI to navigate and explore the dataset.

Architecture

  • Query allows users to execute queries. These queries are stored in a MongoDb database.
  • The queries are executed by sending them to a Legend Engine server.
  • The queries refer to Legend models which are sourced from a Legend Metadata(Depot) server.
  • The Depot server sources Legend models from a Maven repository and indexes them in a MongoDb database.
