NAME

Bio::DB::Universal - Artificial database that delegates to specific databases

SYNOPSIS

$uni = Bio::DB::Universal->new();

# by default connects to web databases. We can also
# substitute local databases

$embl = Bio::Index::EMBL->new( -filename => '/some/index/filename/locally/stored');
$uni->use_database('embl',$embl);

# treat it like a normal database. Recognises strings
# like gb|XXXXXX and embl:YYYYYY

$seq1 = $uni->get_Seq_by_id("embl:HSHNRNPA");
$seq2 = $uni->get_Seq_by_acc("gb|A000012");

# with no separator, tries to guess database. In this case the
# _ is considered to be indicative of swissprot
$seq3 = $uni->get_Seq_by_id('ROA1_HUMAN');

DESCRIPTION

Artificial database that delegates to specific databases, with a "smart" (well, smartish) guessing routine for what the ids. No doubt the smart routine can be made smarter.

The hope is that you can make this database and just throw ids at it - for most easy cases it will sort you out. Personally, I would be making sure I knew where each id came from and putting it into its own database first - but this is a quick and dirty solution.

By default this connects to web orientated databases, with all the reliability and network bandwidth costs this implies. However you can subsistute your own local databases - they could be Bio::Index databases (DBM file and flat file) or bioperl-db based (MySQL based) or biocorba-based (whatever you like behind the corba interface).

Internally the tags for the databases are

genbank - ncbi dna database
embl    - ebi's dna database (these two share accession number space)
swiss   - swissprot + sptrembl (EBI's protein database)

We should extend this for RefSeq and other sequence databases which are out there... ;)
