- Status: |

1.4 |
This library was left in pre-alpha stage and is currently not maintained. So it is to be considered dead. |

Please follow these links for similar more active/stable stuff on this topic: |

Note that DB_DataObject and EasyORM are actually RDBMS-OO mappers, |
16 |
|
|
we are currently investigating the persistency layer of MetaL to show what this library is about. |

- Features: |
20 |
|
|
- Abstract database wrapper library for accessing/storing data in an object-oriented way. |
21 |
|
|
- Modeled partly like Red Hat's Content and Collaboration Management Platform's data persistence part. |
22 |
|
|
- Uses a subset of the PDL Language for declaring classes and mapping object-fields to columns in relational databases. |
23 |
|
|
- Needs storage library (elib/storage) for handling the sql-related stuff, so this library is completely free of sql |
24 |
|
|
and just cares for a "relational nature" of the underlying storage. |
25 |
|

- Notes: |
28 |
|

|
|
This library was written in 2001 when CCM ( http://ccm.redhat.com/ ) still was |
30 |
|
|
ArsDigita ( http://developer.arsdigita.com/ ) , so the concepts used for storing data in CCM |
31 |
|
|
may or may not have changed since then. |
32 |
|
|
|
33 |
|
|
The PDL Language used in this context is neither "The Perl Data Language", the "Page Description Language", |
34 |
|
|
the "Programming Definition Language", the "Project Description Language" nor the "Physical Design Language". |
35 |
|
|
It is the "Persistence Definition Language", see "2.4.1. The PDL File" at |
36 |
|
|
http://ccm.redhat.com/doc/core-platform/5.0/infrastructure/persistence/doc/data-objects-tutorial-beginning.html#data-objects-tutorial-beginning-pdl-object-type-file |
37 |
|
|
There is already the "Persistency Definition Language", which seems to address the same things, |
38 |
|
|
see http://www.cs.ubc.ca/~kdvolder/Workshops/ASE2002/DMP/papers/02matar.pdf . |
