# Bio::DB::SeqFeature::Store::berkeleydb3(3pm)

## NAME

Bio::DB::SeqFeature::Store::berkeleydb3 -- Storage and retrieval of sequence annotation data in Berkeleydb files

## SYNOPSIS

```
  # Create a feature database from scratch
  $db     = Bio::DB::SeqFeature::Store->new( -adaptor => 'berkeleydb',
                                             -dsn     => '/var/databases/fly4.3',
                                             -create  => 1);
  # get a feature from somewhere
  my $feature = Bio::SeqFeature::Generic->new(...);
  # store it
  $db->store($feature) or die "Couldn't store!";
```

## DESCRIPTION

This is a faster version of the berkeleydb storage adaptor for Bio::DB::SeqFeature::Store. It is used automatically when you create a new database with the original berkeleydb adaptor. When opening a database created under the original adaptor, the old code is used for backward compatibility.

Please see Bio::DB::SeqFeature::Store::berkeleydb for full usage instructions.

## BUGS

This is an early version, so there are certainly some bugs. Please use the BioPerl bug tracking system to report bugs.
