Chris,
I myself am learning about all this: C#, CLR, mono, and libgda/gnome-db. =
It's rather exciting!
What is the difference between libgda and gnome-db?
Libgda is a non-GUI data access for Linux/Unix. Hence its name GDA =
stands for GNU Data Access.
It does not depend on gnome, but it does depend on glib, ORBit, bonobo, =
GConf, and the native database libraries.
The use of ORBit and Bonobo in libgda allow it to be used in other =
languages besides C. =20
Libgda does support databases that work on other platforms, such as, =
Oracle. If there isn't a provider for your database, libgda provides =
the infrastructure to create your own. =20
Libgda 0.2.9x is for Glib 1.x uses a similar concept that ADO uses while =
Libgda 0.8.x is for Glib 2.x uses a similar approach that ADO.NET uses. =
I'm not sure on the later libgda, but I am certain on the earlier =
libgda. I have programmed in ADO and libgda 0.2.95, and I think libgda =
compliments ADO very well. It is easy to use even though libgda is =
written in C.
Gnome-DB is the GUI data access for Linux/Unix. It uses Gnome and =
Libgda.
Gnome-DB 0.2.9x uses Gnome 1.x and libgda 0.2.9x while Gnome-DB 0.8.x =
uses Gnome 2.x and libgda 0.8.x.
I haven't played with the Gnome-DB 0.8.x that is for Gnome2, but I have =
played with Gnome-DB 0.2.9x for Gnome1.x, and it has many data bound =
controls (or in gtk-speak, many data bound widgets).
As for creating System.Data.Gda, I don't know if anyone else has started =
working on getting GDA to work in mono C#. I don't want to step on any =
toes. Is anybody? If not, does anybody have any objections to creating =
System.Data.Gda?
Thanks,
-=3D Daniel

Subject: Re: [Mono-list] System.Data
Daniel,
It would be great to have your assistance. I have been working on the =
System.Data namespace, and that is coming along great. However, I do =
not know enough to write any of the managed providers =
(System.Data.OleDB, System.Data.SqlClient, etc..)
I'm not familiar with libgda, but briefly looking at the api, I =
suppose writing System.Data.Gda as a wrapper would work fine, as well as =
System.Data.GnomeDB.
What are the differences between GnomeDB and libgda?
My comments earlier about GnomeDB not fitting into the new ADO.Net =
were somewhat of a misunderstanding. On the Mono website, it says that =
we could just write a wrapper to GnomeDB. This was only meant as =
creating a System.Data.GnomeDB namespace, where as I thought it meant =
System.Data. This confussion was due to my lack of knowledge about =
GnomeDB.
On the topic of managed providers, one of the things I would really =
like to see is, someone write (if possible) the SqlClient and OleDB =
providers. This hopefully would allow linux boxes to talk to MS SQL =
Server, and would open up new web application markets. I know alot of =
companies that use Win2k and IIS, only because they don't like the =
Databases that are available on Linux, and Linux doesnt talk to MS SQL =
Server. I believe that's correct anyway.
Well, once again, System.Data.Gda sounds like a good idea to me. I'll =
be watching the cvs tree for your code.
Thanks,
Chris Podurgiel

Subject: Re: [Mono-list] System.Data
Hello Chris,
I am interested in working in the System.Data namespace. Since =
Gnome-DB doesn't exactly fit into ADO.NET, couldn't we at least create a =
namespace to use libgda through C#? Such as, System.Data.Gda?
I don't know much about C# nor ADO.NET, but I have been playing with =
libgda 0.2.9x on Linux, and I like what I've seen so far. I haven't =
played with the Gnome2 version of libgda which is libgda 0.8.x.
I have seen the framework for System.Data in the mcs classes.
Would you like any help?
Thank you,
Daniel
