NAME

       Alzabo::Schema - Schema objects

SYNOPSIS

	 use base qw(Alzabo::Schema);

DESCRIPTION

       This is the base class for schema objects..

METHODS

       name

       Returns a string containing the name of the schema.

       table ($name)

       Returns an "Alzabo::Table" object representing the specified table.

       An "Alzabo::Exception::Params" exception is throws if the schema does not contain the table.

       tables (@optional_list)

       If no arguments are given, this method returns a list of all "Alzabo::Table" objects in the schema, or in a scalar context the number of
       such tables.  If one or more arguments are given, returns a list of table objects with those names, in the same order given (or the number
       of such tables in a scalar context, but this isn't terribly useful).

       An "Alzabo::Exception::Params" exception is throws if the schema does not contain one or more of the specified tables.

       has_table ($name)

       Returns a boolean value indicating whether the table exists in the schema.

       begin_work

       Starts a transaction.  Calls to this function may be nested and it will be handled properly.

       rollback

       Rollback a transaction.

       commit

       Finishes a transaction with a commit.  If you make multiple calls to "begin_work()", make sure to call this method the same number of
       times.

       run_in_transaction ( sub { code... } )

       This method takes a subroutine reference and wraps it in a transaction.

       It will preserve the context of the caller and returns whatever the wrapped code would have returned.

       driver

       Returns the "Alzabo::Driver" object for the schema.

       rules

       Returns the "Alzabo::RDBMSRules" object for the schema.

       sqlmaker

       Returns the "Alzabo::SQLMaker" object for the schema.
