Synopsis
See Bio::DB::GFF
Description
This adaptor implements a specific mysql database schema that is
compatible with Bio::DB::GFF. It inherits from
Bio::DB::GFF::Adaptor::dbi, which itself inherits from Bio::DB::GFF.
The schema uses several tables:
    fdata
    This is the feature data table. Its columns are:
-
fid feature ID (integer)
fref reference sequence name (string)
fstart start position relative to reference (integer)
fstop stop postion relative to reference (integer)
ftypeid feature type ID (integer)
fscore feature score (float); may be null
fstrand strand; one of "+" or "-"; may be null
fphase phase; one of 0, 1 or 2; may be null
feature_id group ID used to be 'gid' (integer)
ftarget_start for similarity features, the target start position (integer)
ftarget_stop for similarity features, the target stop position (integer)
    Note that it would be desirable to normalize the reference sequence
name, since there are usually many features that share the same
reference feature. However, in the current schema, query performance
suffers dramatically when this additional join is added.
    cmap_feature (replaces fgroup)
    This is the group table. There is one row for each group. This is the
shared table between CMap and GBrowse. There are many CMap related
columns but only a few that GBrowse uses.
    GBrowse Columns:
    feature_id     the group ID (integer)
gclass the class of the group (string)
feature_name the name of the group (string)
    The group table serves multiple purposes. As you might expect, it is
used to cluster features that logically belong together, such as the
multiple exons of the same transcript. It is also used to assign a
name and class to a singleton feature. Finally, the group table is
used to identify the target of a similarity hit. This is consistent
with the way in which the group field is used in the GFF version 2
format.
    The cmap_feature.feature_id field joins with the fdata.feature_id field.
    Examples:
  mysql> select * from cmap_feature where feature_name='sjj_2L52.1';
+--------------+-------------+--------------+
| feature_id | gclass | feature_name |
+--------------+-------------+--------------+
| 69736 | PCR_product | sjj_2L52.1 |
+--------------+-------------+--------------+
1 row in set (0.70 sec)
mysql> select fref,fstart,fstop from fdata,cmap_feature where gclass='PCR_product' and feature_name = 'sjj_2L52.1' and fdata.feature_id=cmap_feature.feature_id; +---------------+--------+-------+ | fref | fstart | fstop | +---------------+--------+-------+ | CHROMOSOME_II | 1586 | 2355 | +---------------+--------+-------+ 1 row in set (0.03 sec)
    ftype
    This table contains the feature types, one per row. Columns are:
    ftypeid      the feature type ID (integer)
fmethod the feature type method name (string)
fsource the feature type source name (string)
    The ftype.ftypeid field joins with the fdata.ftypeid field. Example:
  mysql> select fref,fstart,fstop,fmethod,fsource from fdata,cmap_feature,ftype 
where gclass='PCR_product'
and feature_name = 'sjj_2L52.1'
and fdata.feature_id=cmap_feature.feature_id
and fdata.ftypeid=ftype.ftypeid;
+---------------+--------+-------+-------------+-----------+
| fref | fstart | fstop | fmethod | fsource |
+---------------+--------+-------+-------------+-----------+
| CHROMOSOME_II | 1586 | 2355 | PCR_product | GenePairs |
+---------------+--------+-------+-------------+-----------+
1 row in set (0.08 sec)
    fdna
    This table holds the raw DNA of the reference sequences. It has three
columns:
    fref          reference sequence name (string)
foffset offset of this sequence
fdna the DNA sequence (longblob)
    To overcome problems loading large blobs, DNA is automatically
fragmented into multiple segments when loading, and the position of
each segment is stored in foffset. The fragment size is controlled by
the -clump_size argument during initialization.
    fattribute_to_feature
    This table holds "attributes", which are tag/value pairs stuffed into
the GFF line. The first tag/value pair is treated as the group, and
anything else is treated as an attribute (weird, huh?).
 CHR_I assembly_tag Finished     2032 2036 . + . Note "Right: cTel33B"
CHR_I assembly_tag Polymorphism 668 668 . + . Note "A->C in cTel33B"
    The columns of this table are:
    fid                 feature ID (integer)
fattribute_id ID of the attribute (integer)
fattribute_value text of the attribute (text)
    The fdata.fid column joins with fattribute_to_feature.fid.
    fattribute
    This table holds the normalized names of the attributes. Fields are:
  fattribute_id      ID of the attribute (integer)
fattribute_name Name of the attribute (varchar)
In addition to implementing the abstract SQL-generating methods of
Bio::DB::GFF::Adaptor::dbi, this module also implements the data
loading functionality of Bio::DB::GFF.
 Title   : new
Usage : $db = Bio::DB::GFF->new(@args)
Function: create a new adaptor
Returns : a Bio::DB::GFF object
Args : see below
Status : Public
The new constructor is identical to the "dbi" adaptor's new() method,
except that the prefix "dbi:mysql" is added to the database DSN identifier
automatically if it is not there already.
  Argument       Description
-------- -----------
-dsn the DBI data source, e.g. 'dbi:mysql:ens0040' or "ens0040" -user username for authentication -pass the password for authentication

 Title   : schema
Usage : $schema = $db->schema
Function: return the CREATE script for the schema
Returns : a list of CREATE statemetns
Args : none
Status : protected
This method returns a list containing the various CREATE statements
needed to initialize the database tables.
make_classes_querycodeprevnextTop
 Title   : make_classes_query
Usage : ($query,@args) = $db->make_classes_query
Function: return query fragment for generating list of reference classes
Returns : a query and args
Args : none
Status : public
setup_loadcodeprevnextTop
 Title   : setup_load
Usage : $db->setup_load
Function: called before load_gff_line()
Returns : void
Args : none
Status : protected
This method performs schema-specific initialization prior to loading a
set of GFF records. It prepares a set of DBI statement handlers to be
used in loading the data.
load_gff_linecodeprevnextTop
 Title   : load_gff_line
Usage : $db->load_gff_line($fields)
Function: called to load one parsed line of GFF
Returns : true if successfully inserted
Args : hashref containing GFF fields
Status : protected
This method is called once per line of the GFF and passed a series of
parsed data items that are stored into the hashref $fields. The keys are:
 ref          reference sequence
source annotation source
method annotation method
start annotation start
stop annotation stop
score annotation score (may be undef)
strand annotation strand (may be undef)
phase annotation phase (may be undef)
group_class class of annotation's group (may be undef)
group_name ID of annotation's group (may be undef)
target_start start of target of a similarity hit
target_stop stop of target of a similarity hit
attributes array reference of attributes, each of which is a [tag=>value] array ref
get_feature_idcodeprevnextTop
 Title   : get_feature_id
Usage : $integer = $db->get_feature_id($ref,$start,$stop,$typeid,$groupid)
Function: get the ID of a feature
Returns : an integer ID or undef
Args : none
Status : private
This internal method is called by load_gff_line to look up the integer
ID of an existing feature. It is ony needed when replacing a feature
with new information.
get_table_idcodeprevnextTop
 Title   : get_table_id
Usage : $integer = $db->get_table_id($table,@ids)

This internal method is called by load_gff_line to look up the integer
ID of an existing feature type or group. The arguments are the name
of the table, and two string identifiers. For feature types, the
identifiers are the method and source. For groups, the identifiers
are group name and class.
This method requires that a statement handler named lookup_$table,
have been created previously by setup_load(). It is here to overcome
deficiencies in mysql's INSERT syntax.

get_dnaTop
 Title   : get_dna
Usage : $string = $db->get_dna($name,$start,$stop,$class)
Function: get DNA string
Returns : a string
Args : name, class, start and stop of desired segment
Status : Public
This method performs the low-level fetch of a DNA substring given its
name, class and the desired range. This should probably be moved to
the parent class.
