Terminology

• SubQuery Project (where the magic happens): A definition (@subql/cli) of how a SubQuery Node should traverse and aggregate a projects network and how the data should be transformed and stored to enable useful GraphQL queries.
• SubQuery Node (where the work is done): A package (@subql/node) that will accept a SubQuery project definiton, and run a node that constantly indexes a connected network to a database.
• SubQuery Query Service (where we get the data from): A package (@subql/query) that interacts with the GraphQL API of a deployed SubQuery node to query and view the indexed data.
• GraphQL (how we query the data): A query langage for APIs that is specifically suited for flexible graph based data - see graphql.org.
