  - isRemote
```
boolean isRemote()
```
    Returns boolean indication of remote or not
    Returns:true if the server denotes a REMOYTE connection, false if LOCAL connection
  - getConfiguration
```
EDMRow getConfiguration()
                 throws EdmiException

    Retrieve a memory instance representing EDM internal configuration for this interface. Use getAttrBN and setAttrBN to modify data in memory, and "flush()" to write back to database/interface.
    Returns:internal settings wrapper.Throws:EdmiException - if the method fails
  - communication
```
EDMRow communication()
              throws EdmiException
```
    Retrieve communication paramneter set
    Returns:communication parameter wrapperThrows:EdmiException - if the method fails
  - isConnected
```
boolean isConnected()
             throws EdmiException
```
    Check connection status for server
    Returns:true if the server is connectedThrows:EdmiException - If the method fails.
  - connect
```
void connect(java.lang.String password)
      throws EdmiException
```
    Connect to the EDMServer
    Parameters:password - superuser password, null if not relevantThrows:EdmiException - If the method fails.
  - disconnect
```
void disconnect()
         throws EdmiException
```
    Disconnecti from the the EDMserver
    Throws:EdmiException - If the method fails.
  - getDatabase
```
EDMDatabase getDatabase(java.lang.String location,
                        java.lang.String database_name,
                        java.lang.String password)
                 throws EdmiException
```
    Get a wrapper for an existing or non-existing EDM database.
    Parameters:location - Specifies the path to the directory where the database is located. The location can be specified as an absolute path or as a relative path to the working directory of the actual EDMserver. The location argument can be specified with and without the directory delimiter character as the last character in the directory path. The directory delimiter character is '\\' on the Windows platforms and '/' on the Unix platforms.database_name - Specifies the name of the EDMdatabase. EDMdatabase names are case sensitive on the UNIX platforms and case insensitive on the Windows platforms.password - Specifies the password for the actual database. The password for the database is defined when a new EDMdatabase is created.Returns:Database wrapperThrows:EdmiException - If the method fails.
  - isDatabaseOpen
```
boolean isDatabaseOpen()
                throws EdmiException
```
    Check if the database is open
    Returns:trtrue if the database is open false elseThrows:EdmiException - If the method fails
