!CHAPTER HTTP Interface for Databases

!SUBSECTION Address of a Database

Any operation triggered via ArangoDB's HTTP REST API is executed in the context of exactly
one database. To explicitly specify the database in a request, the request URI must contain
the database name in front of the actual path:

    http://localhost:8529/_db/mydb/...

where `...` is the actual path to the accessed resource. In the example, the resource will be
accessed in the context of the database `mydb`. Actual URLs in the context of `mydb` could look
like this:

    http://localhost:8529/_db/mydb/_api/version
    http://localhost:8529/_db/mydb/_api/document/test/12345
    http://localhost:8529/_db/mydb/myapp/get
