- Determines if the Network Server is running
 
- Creates the NSSimpleDB database if it is not already
created
 
- Obtains an embedded database connection 
 
- Tests the database connection by executing a sample query
 
- Allows client connections to connect to the server until you decide to
stop the server and exit the program
 
- Closes the connection
 
- Shuts down the Network Server before exiting the program
