Persistency Library: Eiffel LIST-orientated XML Database

The Eiffel LIST-orientated XML Database library has 11 classes.

ECF: xml-db.ecf

Status: No longer maintained

A simple XML database based on VTD-XML xpath and XML parsing library. Supports transactions and encryption. Any list conforming to LIST [EL_STORABLE_XML_ELEMENT] can be turned into a database. This library has now been superceded by Eco-DB.ecf which is faster, more powerful and uses a binary format.

EL_STORABLE_XML_EDITIONS_LIST

Object to record to disk any editions made to current list of XML storable objects. If the list is reloaded the editions can be reapplied restoring the state of the previous application session.

The benefits are twofold:

1. A large list need not be saved each time the application exits as the most
                                              recent editions are recorded to disk.

2. If the application crashes unexpectedly, no data is lost.
