   Using and managing an NDB Cluster requires several specialized
    programs, which we describe in this chapter. We discuss the purposes
    of these programs in an NDB Cluster, how to use the programs, and
    what startup options are available for each of them.
  </p>
  <p>
   These programs include the NDB Cluster data, management, and SQL
    node processes (
