NAME

       Alzabo::Create::ColumnDefinition - Column definition object for schema creation

SYNOPSIS

         use Alzabo::Create::ColumnDefinition;

DESCRIPTION

       This object holds information on a column that might need to be shared with another
       column.  The reason this class exists is that if a column is a key in two or more tables,
       then some of the information related to that column should change automatically in
       multiple places whenever it changes at all.  Right now this is only type ('VARCHAR',
       'NUMBER', etc) and length/precision information.  This object also has an 'owner', which
       is the column which created it.

INHERITS FROM
