+As part of Gatsby's data layer, GraphQL queries can be specified as tagged graphql expressions at the bottom of your component source file (e.g. [query for Gatsby frontpage](https://github.com/gatsbyjs/gatsby/blob/master/www/src/pages/index.js#L142)), StaticQueries within your components (e.g. [showcase site details](https://github.com/gatsbyjs/gatsby/blob/master/www/src/components/showcase-details.js#L96)), or fragments created by plugins (e.g. [gatsby-source-contentful](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby-source-contentful/src/fragments.js)).

It doesn't apply to queries involved in the creation of dynamic pages through your site's `gatsby-node.js` file (e.g. on [Gatsby's website](https://github.com/gatsbyjs/gatsby/blob/master/www/src/utils/node/docs.js#L42)).

-Almost all logic to do with queries is in the internal-plugin [query-runner](https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby/src/internal-plugins/query-runner). There are two steps involved in a Query's life time. The first is extracting it, and the second is running it. These are separated into two bootstrap phases.
