=head1 NAME
sqlt-graph - Automatically create a graph from a database schema
=head1 SYNOPSIS
./sqlt-graph -d|--db|-f|--from=db_parser [options] schema.sql
Options:
-l|--layout Layout schema for GraphViz
("dot," "neato," "twopi"; default "dot")
-n|--node-shape Shape of the nodes ("record," "plaintext,"
"ellipse," "circle," "egg," "triangle," "box,"
"diamond," "trapezium," "parallelogram," "house,"
"hexagon," "octagon," default "record")
-o|--output Output file name (default STDOUT)
-t|--output-type Output file type ("canon", "text," "ps," "hpgl,"
"pcl," "mif," "pic," "gd," "gd2," "gif," "jpeg,"
"png," "wbmp," "cmap," "ismap," "imap," "vrml,"
"vtx," "mp," "fig," "svg," "plain," default "png")
-c|--color Add colors
--cluster Cluster tables
--no-fields Don't show field names
--height Image height (in inches, default "11",
set to "0" to undefine)
--width Image width (in inches, default "8.5",
set to "0" to undefine)
--fontsize custom font size for node and edge labels
--fontname name of custom font (or full path to font file) for
node, edge, and graph labels
--nodeattr attribute name and value (in key=val syntax) for
nodes; this option may be repeated to specify
multiple node attributes
--edgeattr same as --nodeattr, but for edge attributes
--graphattr same as --nodeattr, but for graph attributes
--natural-join Perform natural joins
--natural-join-pk Perform natural joins from primary keys only
--show-datatypes Show datatype of each field
--show-sizes Show column sizes for VARCHAR and CHAR fields
--show-constraints Show list of constraints for each field
-s|--skip Fields to skip in natural joins
--skip-tables Comma-separated list of table names to exclude
--skip-tables-like Comma-separated list of regexen to exclude tables
--debug Print debugging information
--trace Print parser trace info
=head1 DESCRIPTION
This script will create a graph of your schema. Only the database
driver argument (for SQL::Translator) is required. If no output file
name is given, then image will be printed to STDOUT, so you should
redirect the output into a file.
The default action is to assume the presence of foreign key
relationships defined via "REFERNCES" or "FOREIGN KEY" constraints on
the tables. If you are parsing the schema of a file that does not
have these, you will find the natural join options helpful. With
natural joins, like-named fields will be considered foreign keys.
This can prove too permissive, however, as you probably don't want a
field called "name" to be considered a foreign key, so you could
include it in the "skip" option, and all fields called "name" will be
excluded from natural joins. A more efficient method, however, might
be to simply deduce the foreign keys from primary keys to other fields
named the same in other tables. Use the "natural-join-pk" option
to achieve this.
If the schema defines foreign keys, then the graph produced will be
directed showing the direction of the relationship. If the foreign
keys are intuited via natural joins, the graph will be undirected.
Clustering of tables allows you to group and box tables according to
function or domain or whatever criteria you choose. The syntax for
clustering tables is:
cluster1=table1,table2;cluster2=table3,table4
