Hi Bill - Sorry I don't have any more info on this.
Of course, databases tend to concentrate on back-end processing, providing no UI components. I have a bit of an obsession with user-friendly data grids and visual query builders, and I've been searching for years for a decent open-source package which offers these. Many years ago I recall running across some VCL data grids for Delphi from companies like FIBPlus and Devrace which looked promising. (As we know, Delphi seems to have fallen by the wayside as a development tool for Windows.) These components from FIBPlus and Devrace may also be available in C++ editions so they may be usable in a VB environment rather than .NET. They may also offer open-source versions. There is a set of components for .NET and WPF from Xceed which has a bunch of really nice data-grids. I don't think they're open source. Finally in the browser area there is of course the recent plethora of open-source Ajax libraries (JQuery, YUI, MooTools, DWR, Tibco, ExtJS) which have started to appear, some of which offer some fairly sophisticated data grids. My personal favorite, in terms of sheer "wow" factor, is ExtJS. They have an excellent on-line demo here: http://www.extjs.com/deploy/dev/examples/ <http://www.extjs.com/deploy/dev/examples/>There's also a couple of libraries built on top of ExtJS: SmartClient / SmartGWT, and two other combos of Ext+GWT (I keep getting them mixed up - one is called GXT I think). I heard that ExtJS pissed off a lot of developers by changing their licencing from LGPL to GPL, but it does offer one of the most attractive-looking UIs for the web. I have no idea how any of these might work with J. I would love to be able to make browser-based databases with, say, ExtJS on the front-end and J on the back-end. I think I might be able to get the basics worked out, but I'm concerned I might not know how to handle important issues like validating and updating data from multiple concurrent users. 2010/6/10 bill lam <[email protected]> > Чтв, 10 Июн 2010, Stefan Scott Alexander писал(а): > > - provide a rich user interface including things like: > > - - - grids having custom cell editors (eg, a calendar control in a date > > cell, a multi-column combo-box control in a cell referencing a foreign > key, > > maybe even a graphic in a cell), "freezable" left-hand grid columns, etc. > - > > > - - - a user-friendly visual query builder similar to the one in > MS-Access > > I'm also interested to know which open-source databases provide these > functionalities.
