This module is meant to be used a part of the OBDA system, e.g.:

  use Bio::DB::Registry;

  my $registry = Bio::DB::Registry->new;
  my $db = $registry->get_database('biosql');
  my $seq = $db->get_Seq_by_acc('P41932');


This module connects code that uses OBDA to the bioperl-db package and the underlying BioSQL database.

The Open Biological Database Access (OBDA) system was designed so that one could use the same application code to access data from multiple database types by simply changing a few lines in a configuration file. See for more information.


Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.


Please direct usage questions or support issues to the mailing list:

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
