My 10 cents to the SqueakDBX list of actions......
Long time ago, when I learnt about the VW UI Builder, I attempted to run an existing sample code that was basically a dataset widget browsing a collection of objects, and then I wrote some code to make them persistent using ObjectLens and Oracle.
Later on time, I would say 12+ years later, I learnt about GLORP and wrote a morphic-based dialog to do the most simple CRUD model to teach myself persisting objects into PostgreSQL using Glorp and a GUI.
My suggestion to the SqueakDBX team is to incllude a working sample but this time based on the Morphic UI Designer.
Got it. And what about Seaside for example? Few years back, we used to have a Seaside + GlorpDBX + SqueakDBX example that we used for the university thesis. However, I guess it is quite outdated and note sure if it works. But maybe we should do that. I think it is a good idea. In addition, we can use the same example for the PBE chapter. Finally, I remember an ESUG project which idea was a open source application based in pharo, seaside, glorp, etc, to use as an example/learning. I don't remember the name right now....but it would be awesome if that app could be changed to use GlorpDBX + SqueakDBX instead :) thanks mariano

Certainly all the Smalltalk community should thank ESUG by the continous support to lot of initiatives.
And to ESUG sponsors :) and ESUG conference attendees...and...and..lots of people :)
Thanks ESUG.
2011/3/4 Mariano Martinez Peck <marianopeck@gmail.com>:
We are really happy to announce that ESUG will sponsor us once again through the ESUG Summer Talk project. This means that we have reached the ESUG expectations and that they still think that relational database access is an important matter in Smalltalk.
One important thing is that we are going to rename the project (we are still working on it) since SqueakDBX runs not only in Squeak but also in Pharo, and there have been even ports to Dolphin. What's the reason for this decision? Because we do not want to couple ourselves to a smalltalk dialect nor to OpenDBX, because our project is much more than that (later I will tell you about our plans). So, these are some of the possible names: ObjectPark, SmallParking, Parktalk, SmallValet, Valetalk, ValetST, NorayTalk, Ballard, Noray and Cruise. Please let us know which one is your favourite or help us find a new one.
Another important subject is the team. There will be three "mentors", Esteban Lorenzano, Diogenes Moreira and myself, Mariano Martinez Peck; and three students: Guillermo Polito, Nicolas Scarcella and Santiago Bragagnolo.
We are open to suggestions and ideas. In addition, we have defined a possible list of actions that I copy at the end of the email.
For the moment, the url remains www.squeakdbx.org and the mailing list squeakdbx@lists.squeakfoundation.org
Once again, we want to thank ESUG for their support and trust.
Thank you very much,
SqueakDBX team
Possible list of actions:
1) Change SqueakDBXâs name.
2) Update GLORP version since the actual one is 3 years old.
Port it again from VisualWorks, create a VW porting tool (may be). Complete support to Glorp. Today it works with PostgreSQL, Oracle and MySQL. Make it work with most databases OpenDBX supports.
3) Create a lightweight solution, alternatively to GLORP. There are some options:
Make SqueakSave work with SqueakDBX. SqueakSave developers already contacted us because they wanted to do it. SqueakSave seems to be 20% slower than Glorp but you don't need to write the mappings :) Adapt Ramon Leon's active record to use an abstract database driver, and create a driver for SqueakDBX. Port the new Glorpâs kind of active record to Pharo. (included in 2).
4) Write a Pharo By Example 2 chapter based on the card game Stef built ;).
5) Cog compatibility.
6) Use Alien instead of FFI. Eliot is working on a threaded CogVM. One of the projects of the GSoC of this year was to make something similar to a threaded FFI. What the student did is a modification in Alien (I think) that can be run in a multithreaded envirorment. He worked with Eliot. The idea is when Eliot releases the threaded CogVM, this FFI would work our of the box, and would avoid locking the WHOLE vm while a C function is being invoked (as it happens today with FFI).....So....when that VM is released, we MUST migrate to that).
7) Explore performance issues (maybe with our approach of "In thread execution plugin").
8) Complete integration with OpenDBX. For example, Oracle, for large objects (Clob, Blob, etc) use specific functions. There are specific functions in OpenDBX that have to be used if the database uses specific functions (oracle is the only one for the moment.). We don't manage those functions yet.
9) In this link http://www.squeakdbx.org/Targets%20and%20Features You can see a list of future possible features like Connection pooling (now it is done!), Prepared statement interface, Store procedures, Escape and avoid of SQL insertion, Authentication support: extends to other methods, not only user/password, Full text support, etc.
