[GENERAL] naked objects from stored procedures, interface generation
Hallo, there exist many framework that 'backward' engineer from a programming language to database to make the data persistent. so: code >> db (generated) eg. hibernate, turbogears many others My question is, from db point of view, do we have such frameworks that work the other way, ie that forward engineer from a database to a user interface (web or program), maybe using the stored procedures available on the database (eg in the same naked objects work) so: exisiting db (possible + stored procedures) >> user interface (eg crud or other) mvg, Wim -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
Re: [GENERAL] naked objects from stored procedures, interface generation
Hello I know about one similar project - Garuda, but this project isn't open. What it does: * OOP - objects, properties, methods - not based on PostgreSQL OOP * support of workflow - lifecycle for objects * support of collection of objects It was designed in plpgsql with special modules to PHP, where was possible to work with Garuda objects like PHP objects.

What's the easiest way, in PostgreSQL 9.0, to keep a duplicate database on my local machine updated at intervals from another on a remote machine without having to reset permissions after a backup/restore.

Re: [GENERAL] "could not accept SSPI security context"
thanks a lot for the hints. All connections I tried used the IP address of the pg server. Also the service name should be the default one. I tried setting the sspitarget in SSPIHandler.cs to all sorts of variations, including fully qualified names. The error remains exactly the same, even when I set sspitarget to nonsensical values. I'll discuss this with our IT in january. Maybe there IS some inconsistency in those AD accounts, only that the authentication from libpq can cope with that. From afar it seems that the calls to AcquireCredentialsHandle() and InitializeSecurityContext() in npgsql and libpq do the same thing though.

[GENERAL] Stitch Large Panorama
Hi, there, First of all, happy holidays to every one! I wish all of you the best in the coming 2011. I recently released a large panorama on Gigapan at http://www.gigapan.org/gigapans/66626/ . This panorama received many serious debate about the true pixel count. Since I used Autopano, my argument was, when there is no standard way to calculate the total pixel count, we should not manipulate the software output, rather, everyone use the same baseline. Then everyone should also provide theoretical estimation of the optical pixel count. In this case, 112G pixels. The questions here are: 1. Is there a way to stitch super size panorama in PTGUI? Can we emit raw files so that it is not subjected to image format limit? 2. Is there a way to import Autopano config file and process in PTGUI? 3. Can PTGUI accurately report the optical pixel count for super size panorama? Thanks!
