DESCRIPTION
DBD::Amazon provides a DBI and SQL syntax abstraction for the Amazon(R)
E-Commerce Services 4.0 API *aka* ECS. .
Using the REST interface, and a limited SQL dialect, it provides a
DBI-friendly interface to ECS.
Be advised that this is ALPHA release software and subject to change at
the whim of the author(s).
Prerequisites
Perl 5.8.0
DBI 1.42 minimum
SQL::Statement 1.14
SQL::Amazon 0.10 (included in this bundle)
Clone 0.15
Testing Considerations
To run the test package, you'll need
An Amazon ECS User ID
An environment variable DBD_AMZN_USER must be set to an Amazon ECS
user ID in order to connect and execute ECS requests. Registration
at the Amazon Web Services site is required to acquire a user ID.
An Internet Connection
Obviously.
Patience
Some of these tests download large amounts of Amazon catalog data,
which can take some time (esp. since a minimum 1 second delay
between requests is required).
Also, be prepared for possible intermittent 'Internal Error' reports;
these are problems within the Amazon ECS system, not failures in
DBD::Amazon itself.
Installation
For Unix:
*gunzip/untar as usual, then*
cd DBD-Amazon-0.10
perl Makefile.PL
make
make test
make install
Note that you probably need root or administrator permissions to
install. Refer to ExtUtils::MakeMaker for details on installing in your
own local directories.
For Windows:
*Unzip with your favorite utility, e.g., WinZIP, then*
cd DBD-Amazon-0.10
perl Makefile.PL
nmake
nmake test
nmake install
SQL Dialect
DBD::Amazon supports a subset of standard SQL, and additional predicate
functions for keyword searches. Review SQL::Amazon::Parser and
SQL::Statement for syntax details.
Use "table_info()" to retrieve the metadata for any of the defined
tables/views.
Currently, only the following tables are defined:
Books
Offers
CustomerReviews
EditorialReviews
BrowseNodes
ListManiaLists
Merchants

ACKNOWLEDGEMENTS
Many thanks to Jeff Zucker for his guidance/patience, and adding some
nice new features to SQL::Statement to help make DBD::Amazon a reality.
