Prevayler OO DB

Sandro Groganz Leave a comment

From the Prevayler Web site [1]:

“Prevayler is the most reliable Free Software Prevalence layer we are capable of providing for Java.”

“With Prevalence we are finally free to create true object servers and use objects the way they were intended all along.

We are able to use any algorithm, data-structure and query language we please. We are no longer constrained to the ones provided by database and application servers which must run on disk data-blocks.

We believe the whole OO community is finally free to recover from the atrophy caused by database and application server restraints. We no longer have to distort and maim our object models to satisfy their limitations.

We no longer have DBAs imposing us database layout restrictions. We have freed them to do something more useful.

We have set fire to the table-models on our walls. We have deleted our database creation scripts. We no longer have to keep them updated.

We no longer have to license, install, configure and maintain a database and application server every single time we want to develop, demonstrate or deploy our systems for any of our clients. Give us a Java VM and we are good to go.”

The Next Round of WYSIWYG XML Editing?

Sandro Groganz Leave a comment

The development of two promising Open Source browser-based WYSIWYG XML editors come to the next round:

Giuseppe Bonelli is looking for developers joining him to (re-)start development [1] of the Xopus [2] Open Source version. This is a WYSIWYG XML editor based on MS Internet Explorer.

I am awaiting a profound rewrite of Bitfluxeditor [3], a Mozilla-based WYSIWYG XML editor, which hopefully might happen in the foreseeable future. This rewrite is called BXE-NG (Bitfluxeditor Next Generation) and might be based on Mozile [4]. See the threads in the BXE mailinglist for more infos. [5].
