anchor.diff:  === Connecting to OrientDB from WildFly
   The *orientdb* subsystem may define multiple OrientDB connection profiles, that are used to obtain 
   com.orientechnologies.orient.core.db.OPartitionedDatabasePool class instances that represent each defined profile.  The OPartitionedDatabasePool class
  -is thread safe and can be shared by multiple deployed applications.  If the defined profiles are updated
  -while deployed applications are using them, the applications will be restarted.

   WARNING: The OrientDB client API, is heavily dependent on keeping one OrientDB database open per Java thread.  When your application is done with the database, *you must close the OrientDB database* to disassociate it from the Java thread, or the open database will still be open by that Java thread, when the Java thread is returned to the Java thread pool.  A max of one OrientDB database can be open per Java thread, so if you open a different database, the current one will be automatically closed first.

  The *mongodb* subsystem may define multiple MongoDB connection profiles, that are used to obtain com.mongodb.MongoClient +
  com.mongodb.client.MongoDatabase class instances that represent each defined profile.  The MongoClient/MongoDatabase classes
  are thread safe and can be shared by multiple deployed applications.  If the defined profiles are updated
  while deployed applications are using them, the applications will be restarted.

  The *neo4jdriver* subsystem may define multiple Neo4j connection profiles, that are used to obtain org.neo4j.driver.v1.Driver class instance
