Ian,
This is a very good start. However, there are many, many more items
that could be addressed including:
1) gui mapping tool (for faster mapping)
2) auto-generation of DDL to create database tables
3) large object support (BLOBs/CLOBs)
4) multiple database support
5) two-phase commit
6) multiple inheritence
7) cursoring for large result sets
8) self-referential relations (an object of type Foo related to
another object of type Foo)
9) distributed object caching
10) Enterprise Information Systems support
11) subselect and parellel select support
12) raw SQL support
13) database independence
14) query language support (OQL, SQL, EJBQL, programmatic, etc.)
This list is by no means exhaustive. BTW, does anyone have more to
add? It is simply some of the items I included during the Summer
2001 when I researched object persistence tools, both commercial
and Open Source.
Also, I truly think that any such feature comparison between object
persistence tools should include Object Bridge
(http://objectbridge.sourceforge.net/). This tool is advancing very
quickly in both popularity and functionality.
