NAME

Bio::DB::EUtilities::einfo - NCBI database information

SYNOPSIS

   my $einfo = Bio::DB::EUtilities->new(
                                      -eutil    => 'einfo',
                                      -db       => 'pubmed'
                                       );
 
   print $einfo->get_response->content;
 
 

DESCRIPTION

EInfo queries provide information about NCBI databases. At this time, data is postprocessed for a complete list of Entrez databases (when '-"db"' is not set) or for specific database information, number of entries, date of the last update, or Field or Link information. Using the base URL with no parameters returns a list of all Entrez databases.

Parameters

The following are a general list of parameters that can be used to take advantage of EInfo. Up-to-date help for EInfo is available at this URL (the information below is a summary of the options found there):

   http://eutils.ncbi.nlm.nih.gov/entrez/query/static/einfo_help.html
 
 
"db"
Database parameter. This is optional; not setting this will return a list of all the available Entrez databases. If a database is specified, returned XML data will provide the following information : field names, index term counts, last update, and available links for each Entrez database.
