[Mydm-devel] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Mydm-devel] [ MyDM ] new hsqldb version

[<520...@t-...>]

Hi,=20

now we have the new version of hsqldb 1.7.2 in the cvs, it gives us lot =
of flexibilites in starting the db and stopping.
it resolveslot of bugs with the sequences.

you can update the local copies of
lib/java (dir)
conf (dir)
org.mydm.utilities.bin (package)
org.mydm.db.admin (package)

we have two classes to start and stop the database in server mode.
org.mydm.utilities.bin.StartDBServer
org.mydm.utilities.bin.StopDBServer

LoadData Script is moved away from the hsqldb script tool. Now the =
database is created with the normal SQL (jdbc) statements.
org.mydm.db.admin.CreateDBStructure

Cheers,
VJ.

Hi ,
I guess this is our new first mail in this mailing list, and it starts 
with a big discussion :-)
Last time i was doing some tests on the memory management of the 
Software, and its expensive,
as the XIndice itself is consuming lot of memory around 30 mb and our 
application itself (swing) is consuming
some 36mb. on the whole the application is using some 64mb, which is 
very high for a small Client Application.
we can not expect all users having enough system resources. And i am 
worried about it.

And i also noticed that XML Processing is also very CPU Consuming, so we 
should think about the backend.
I was looking for a light weight data store, which uses flat flat in 
some binary format, but not successful until now.

I found a light weight database engine which is written purely in Java 
and which is opensource.
http://hsqldb.sourceforge.net/
this can be intresting for us. Just to mention this database is not yet 
complete SQL92 complaint, but for us
it is enough if we have fast retrievals and good search possibilitites.

Using a full fledged database like MySQL will be an Overkill for the 
Application.
Any Ideas for the backend..

Cheers,
VJ.
