the database module of the Open Source project OpenOffice.
We (they) are having difficulties with the code in the Base module which allows updateable queries. See http://www.openoffice.org/issues/show_bug.cgi?id=53377 .
i have volunteered to comb the web and place announcements on different sites in order to encourage volunteers to help with the project mainly because i am not a programmer but someone who works in an office and want to be able to use Postgresql at the child development office where i work. We finally got an application working in Access about five years ago but it's not very stable or secure or multi-user ... or free. So, thinking about the taxpayers, we are trying to move away from Access and the MS suite and OpenOffice offers everything, including the gui that we could use to make up the db app., but we are stuck because the API or driver or whatever it is will not allow us to create, through the OOo wizard, an updateable query on two, one-to-many tables.
Pretty long-winded but that's how it is. If more of us non-programmers had access to some sort of gui with wizards, which OOo is striving to provide, we could make up our own database systems. Postgresql is not hard to download or even install (if i can do it...) but i have not been able to find any gui that is free (as in ...) which can be used like Access, i.e. without any knowledge of programming. Anyway, please contact me at the foundation's e-mail if you are interested. Have a great day! :)
