* Aqueduct
The old name for Z SQL Methods. Also connected to a commercial Client-Server model for Zope 1.x and RDBMSs, I believe. Might be deprecated by ZEO?
* Tabula
Now called ZTables, also a commercial Zope add-on. Fast datastorage for Zope, parts of wivh are now part of Zope. The Collector is build using ZTables. ZCatalog is build using the integrated parts.
* Pluggable Brains
Smarter Z SQL record objects. By default a result set of a SQL query consists of pretty dumb classes, but you can define a class (in a module in your Extensions directory) that can be mixed in. See the advanced tab of your Z SQL Method, and the source. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | T: +31 35 7502100 F: +31 35 7502111 | mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ---------------------------------------------
