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. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

The last thing i can remember is, that i did an update of the JDBC sources to a recent version. I think that a new version has been released. I should update them again. I don't have the the sources of SAPDB itself. I don't even know, if they are in CVS already. What makes it worse is, that ftp.sap.com is closed for anonymous at the moment. What about the Sources of the Python and ODBC Driver? |

Hi! The studios screens are needing two urgent works: 1) Look and feel. I'm using "text" buttons for everything, and it could be nicely designed buttons 2) There are some weird bugs in the event handlers, this need much more tests. The other area is that I had no much time to implement the code to reverse procedures, triggers, UDF, UDT and so on. Another work to be done is integration with some syntax-capable editor (I'm using a JTextArea with some kind of "beatufy" work - someone already tryied to read a view from the database tables? SapDB make a "trash" with our code formatting). I'm using the studio in day-by-day operations, and worked fine (one boring bug is that a query window stay open after closing the connections). About the sources, I need to confess with should wait for a response from Sven... I think he updated CVS with latest code some days ago.

SAPDB 7.3 and 7.4 already were GPLed, only the client-libraries were LGPLed. So in the backend, there's no change from SAPDB to MaxDB. The license of the client-libs are the main difference. An example: you need to include the JDBC-driver with your web-app. your webapp would need to be under GPL if you include the MaxDB JDBC driver which is under GPL too. In order order to keep your code from being under GPL, you need to buy MaxDB. As the protocol of MaxDB hasn't changed since SAPDB 7.4, the old JDBC drivers will continue to work with MaxDB, but they will not be fixed, enhanced etc. So that's the point where this project comes in. We will maintain and perhaps restructure the JDBC, ODBC and Python libs, so that people have a free LGPLed product to use. |

Ok, main objective: maintain LGPL versions of all programming =
interfaces: JDBC Driver, ODBC driver, and so on. This is important to =
people who want's to develop comercial software that will use SapDB as =
backend server.
Steps:
1) Wait for latest releases from oficial Sap LGPL drivers;
2) Fix and internationalize, releasing new versions always in LGPL =
license.
3) Less important, create new tools to help database developers and =
administrators.
I expect to translate our wishes in few lines.

Yes, it could be a squirrel-sql modified. But we have some requirements: 1) The tool need to be extensible as SapDB/MaxDB is. It need to have support for all the features SapDB/MaxDB offer, now and in the future (ok, this can be acomplished using squirrel plugins); 2) The tool must follow a UI independence project, so we have by now Swing UI, but we will have JSP UI very, very near (to substitute WebSQL that simply doesn't work at all - is buggy and unstable); 3) It need to be fast, easy to understand, configure and work. More, work in the way SapDB people know it works; 4) Don't depend on JDBC Metadata info, but rely on SapDB System Tables; 5) Be able to design visually the database; 6) Be able to design visually the queries; 7) There is place for other databases in the future. In the way we work, I don't think will be hard to put support to other databases without increasy complexity. The version of Squirrel SQL I've used in the past was slow, hi memory consuming, and can't be extended to work on WEB environment. Maybe actually it's different from the one I've used. I should double-check. Actually, the tool is capable to connect to SapDB servers, execute multiple queries, and edit data directly over tables. We are working on getting objects from database (we already can view a list of tables, and views, and really near, procedures, UDT, sequences, and system tables). The query tool lack a good sql editor, with syntax hilighting, but due the nature of our project (GPL), there will not be hard to adapt (reuse) one from the web. At all, (talking just by me, not by the team) I must confess that has been so funny to implement the Sapforge Studio, and so easy to make it work with all the features I need from SapDB tool, that I think even group decides to create a plugin for Squirrel SQL, I'll continue to work on Sapforge Studio. Again, we can wait and see what the team think about your suggestion, and, of course, I'll accept any decision made by majority.

Hi Edson, Instead of writing SQL Studio from scratch it would be much easier to extend SQuirreL SQL Client <http://sourceforge.net/projects/squirrel-sql> to work specifically for SAPDB. As of now it works with any database through JDBC. If you can spare some time look at the link given above. The one advantage the new SQL Studio has is that, that it looks like SAP's SQL Studio.

Someone has tried to download CVS from sources and run the skeletum of = the new studio? Someone tried the query executor/data editor? I'll be away for a while, but I like if someone could test and = contribute some ideas about usability... AFAIK, our new studio is near to be a good replacement for WEBSQL (we = don`t have a "save command" or "command history" by now, neither a = multi-command script processing, but I think it can be easly put there). = And if someone has time, we can use the infrastructure to build a query = executor based on JSP (too mutch better than actual WEBSQL). ASAP I'll be wrinting a metadata analyzer that will be initially reading = from JDBC Metadata, but can be configured (in future) to read the = SapDB/MaxDB system tables.

Hi, today MaxDB was released. i downloaded latest sources for JDBC, DBMGUI and SQL-Studio. All others should download sources for their part too. The text on http://www.heise.de/newsticker/data/hos-18.11.03-000/ sound very much like MySQL will not provide downloads for SAPDB 7.4 for a very long time. I don't know for how long the sources on ftp.sap.com will continue to exist. |

I agree... As I stated, this is a early coding... There is a lot of "to-d= o" here... A abstraction layer for database access is something I was thinking last night... Several information that is important to studio cannot be obtain= ed just using JDBC. An example was to dected if a resultset is editable or n= ot just before trying to open the resultset. Will give us an error if the resultset is readonly :( But the operations is delegated to a specialized plataform class (in case= , SapDbFactory - this is not the best name, right?). I think we can assume that the abstraction base class is the net.sourceforge.sapforge.studio.session.Session, or we need to refactor s= ome code to avoid high dependency from Session class (besides it's not linked with UI, and it's at heart of the studio). I was able to connect to several SapDB servers at my site (event throught= a firewall and the internet), but remember: you need the SapDB jdbc driver = in class path. After hours of searching the web by confortable XUL implementation to wor= k, I concluded I've wasted my time, and started coding in Swing by my self. = I will not use NetBeans to generate (crappy) swing code. I think someone else should start research XUL or anything else. I've use= d Swing because I work with Swing day-by-day, and is easier to me. SWT isn'= t hard, but then we will need the swt DLL distributed with the app, what ma= ke our app not so portable (besides I think SWT presently has a more professional look). SWT has a pretty editor (SWT Designer, if I not mistake myself), but generate crappy code too, and can't edit menus, so need conding by the wa= y. Interesting the link for pgAdmin. I've looked, and belive me, I've starte= d the Swing UI with a really near approach in mind (even I never got to tha= t site before). We will have a tree at left to see connections and objects, and a desktop pane which content derives from context (select in the tree= ). ----- Original Message -----=20 From: Sven K=F6hler To: sap...@li...

I wasn't abled to connect to my DB (i guess i am to dump at the moment. i've took some medcine to defeat my cold) so i couldn't test it yet. I'll do some code-review in the next days. What about the Database-Abstraction-Layer (DAL)? Is JDBC our database-abstraction-layer? I think we'll miss several things if we continue using JDBC. A DAL would be an extension to the JDBC-API that provides more tools and information. We would have to provide DAL-modules for each Database that's supported. A DAL-module that's based only on JDBC would be possible, but would only provide limited support. ------------------------------------------------------- This SF.net email is sponsored by OSDN developer relations Here's your chance to show off your extensive product knowledge We want to know what you know.

I wasn't abled to connect to my DB (i guess i am to dump at the moment. i've took some medcine to defeat my cold) so i couldn't test it yet. I'll do some code-review in the next days. What about the Database-Abstraction-Layer (DAL)? Is JDBC our database-abstraction-layer? I think we'll miss several things if we continue using JDBC. A DAL would be an extension to the JDBC-API that provides more tools and information. We would have to provide DAL-modules for each Database that's supported. A DAL-module that's based only on JDBC would be possible, but would only provide limited support. |

Hi! You asked, you get it! (kidding about the query executor/data editor). Uau, takes a long time since I last touched our studio source code. Since I think people like to see something (an image is thousand valuable than a million of words), I started to create a simple Swing UI to studio. Execute the net.sourceforge.sapforge.studio.swingui.Main class. By now, we are able to open multiple connections, and keep separate desktop panes for each. The unique real utility avaliable by now is a query executor with data editor (based on javax.swing.TableModel, so don't blame me if it now work like you expect). The data editor is based on type 3 jdbc connections, so it should work fine with our JDBC driver (checkout CVS head from our repository, and compile it). I need too much help on Visual styling (huh, I'm acting as developer, so don't expect beatifull windows from me!). Adding images to buttons, menus and so on. Someone could code a Look and Fell chooser (like the one in Metal sample from Sun)? May be we need to store the user personal preferences for window and split sizes... Next week, I'll be coding the reverse engineer tool to retrieve database structure. Thanks for your attention. Edson Richter --- Outgoing mail is certified Virus Free.

I think we need to put our own software to stop using mis-coded ones =
(the software really need to be so complex? Check JDBC driver... It's =
crazy coded... Just because we need to use Pascal records is not reason =
to not make a OO approach)...
But critisize is easy... Let's see if we can do better ;-)
Someone has seen the code in CVS for the studio? I need volunteers to =
code the Factories for SapDB (starting with DataTypes).
I think a good XML structure for a data type should be like:
<datatype name=3D'VARCHAR'
nullable=3D'ALLOW'
unicode=3D'ALLOW'
internalName=3D'varchar'
encodings=3D'ALLOW' >
<dimensions>
<dimension name=3D'size'
minValue=3D'0'
maxValue=3D'4000' />
</dimensions>
<defaultEncoding>ASCII</defaultEncoding>
</datatype>
And so on (the other characteristcs must be taken from the code).
What do you think?
Edson

Hi, today i received the Announce of DBM 7.4.3.30 - nothing special i thought, but the program installed calls inself "Database Manager Second Edition" and installs inself into the directory DBM2 instead of DBM. I didn't find the sources on ftp.sap.com - is this still a VB program? Well, it takes 20-30 seconds with 100% CPU usage to start DBM2 on a Pentium3 800MHz. I don't know what they did to the good old DBM, but after the GUI is loaded, it takes 30-40 seconds to start the Log-Settings Wizard - again with 100% CPU usage. On a Athlion XP 2000+ this works much better (about 2-5 seconds for each step above). Do you have the same problems? |
