# Bio::DB::GDB(3pm)

Bio::DB::GDB - Database object interface to GDB HTTP query

```
    use Bio::DB::GDB;
```

```
    $gdb = new Bio::DB::GDB;
```

```
    $info = $gdb->get_info(-type => 'marker',
                                          -id => 'D1S243'); # Marker name
```

```
   print "genbank id is ", $info->{'gdbid'},
    "\nprimers are (fwd, rev) ", join(",", @{$info->{'primers'}}),
    "\nproduct length is ", $info->{'length'}, "\n";
```

This class allows connections to the Genome Database (GDB) and queries to retrieve any database objects. See http://www.gdb.org/ or any mirror for details.\
