Detailed Description

A dataset contains in data in a common structure that can be shared and transformed for different purposes easily, examples.

• transform associative arrays into (set-)xml and back (e.g. for import/export)
• transform assiciative arrays into json and back (e.g. for ajax requests)

The general structure is:

• entity name (many times this corresponds to a table name)
• structure (this is a set of field names and types pairs) currently supported types: text, integer, timestamp planned: date, time, clob types correspond to db types, see http://www.ilias.de/docu/goto.php?target=pg_25354_42&client_id=docu
• records (similar to records of a database query; associative arrays)
