NAME

       Tangram::Springfield - classes and schema used in the Guided Tour

SYNOPSIS

	  use Tangram;
	  use Tangram::Springfield;

	  # deploy the storage
	  # store & retrieve objects

DESCRIPTION

       This modules contains the declarations of the classes used in the Guided Tour. It also creates Schema object for that class system, and
       stores it in the $schema variable. That variable is exported to the "main" package by default.

       The UML diagram for the classes can be found in Tangram.

SEE ALSO

       Tangram, Tangram::Schema, Tangram::Relational, Tangram::Storage, Tangram::Deploy.

NAME

       Tangram::Type::TimeAndDate - map date & time fields

SYNOPSIS

	  use Tangram;

	  # any of:
	  use Tangram::Type::Date;   # RAW - use with caution
	  use Tangram::Type::Time;
	  use Tangram::Type::Date::Cooked;   # pure ISO-8601
	  use Tangram::Type::Date::DateTime;
	  use Tangram::Type::Date::Manip;
	  use Tangram::Type::Date::TimePiece;

	  Tangram::Schema->new(
	     classes => {
		 NaturalPerson => {
		    fields => {
			rawdatetime => [ qw( birth death ) ],
			rawdate => [ qw( depart return ) ],
			rawtime => [ qw( breakfast lunch dinner ) ],
			cookeddatetime => [ qw( cooked ) ],
			dmdatetime => [ qw( datemanip ) ],
			timepiece => [ qw( fob ) ],
			datetime => [ qw( bloat ) ],

DESCRIPTION

       These classes are responsible for mapping strings to SQL date or time types. These classes are not imported by Tangram.pm, thus they must
       be explicitly imported via a "use" directive.

       The three typetags "rawdate", "rawtime" and "rawdatetime" are for mapping strings to SQL date/time types, for databases that differentiate
       between "dates" and "times".  'Raw' means that Tangram doesn't attempt to interpret the strings, it merely passes them down to DBI.

       "cookeddatetime" is like "rawdatetime" except that the date is converted from the DBMS format to ISO-8601 in the form :

	 YYYY-MM-DDTHH:MM:SS

       for example:

	 2004-12-25T13:14:15

       Other modules then further cook this ISO date into an object as is the convention for a particular module.  This only works with back-ends
       that allow per-connection settings for the default date format, such as Tangram::Driver::Oracle.

       On the way back out, the date is converted back to the DBMS format.  This is achieved via vendor-specific functions mentioned in "Tan-
       gram::Relational".

       The persistent fields may be specified either as a hash or as an array of field names.

       In the hash form, each entry consists in a field name and an associated option hash. The option hash may contain the following fields:

       * col
       * sql

       "col" sets the name of the column used to store the field's value. This field is optional, it defaults to the persistent field name. Over-
       ride if the field name is not an acceptable SQL column name.

       "sql" sets the SQL type of the column. Used by Schema::deploy() when initializing a database. Defaults to 'VARCHAR(255) NULL' for strings,
       'INT NULL' for ints and 'REAL NULL' for reals.

       The persistent fields may also be specified as an array of strings, in which case the defaults are used.
