Me again, sorry for the trouble!

Hi, Yep, me again, that pesky person with it's dumb questions. Sorry, about these questions, but I want to know everything and because nobody around me knows something of this stuff, I've to ask you... hope you don't mind too much. If you do, please say! Ok, reading the docs and getting your explenations I see that the choice of database (relational or object oriented) depends on the sort of data to store. Well, I don't get this fully... Suppose we've this data to store : Examination table : Examination, Rooms, FieldX, FieldY, FieldZ Rooms Table: Room, Equipements, FieldX, Subexams SubExams Table: .. .. .. This can be be put in a relational table : Examinations : Exa1, Room1, a, b, c Exa1, Room2, c, d, e Exa2, Room1, d, d, d ... But also can be put in a object-oriented way : Exa1 Room1 a b c Room2 c d e Exa2 Room1 d d d .... So what is the best choice???? Tom.

Zope!
by Tom Deprez 26 Apr '99

26 Apr '99

Hi all, Yep, I finally started writing an article about Zope.... I hope, some of you are willing to read/correct it. Oops, I almost forgot: Question to the creators of Zope. May I write an article about Zope? Hope I may. Writing about web-applications. Does somebody has good documentation on these? i.e. what is a web-application etc. At the moment I'm writing down my own thoughts. And last thing. Can we classify Active Server Pages of M$ as a web-application platform? I though so. Regards, Tom.

What happened to some contributed software?
by Philip Aylesworth 26 Apr '99

26 Apr '99

I just went to http://www.zope.org/Download/Contrib to download UserDB or something like that and I can't find it. I am sure there was a contribution that did user authentication using an SQL database. Now I want to do that and I can't find it. I also remember a MySQL insert wizard. Can't find it either! Anybody know where they are?? Phil A.

organizational questions
by Scott Lewis 26 Apr '99

26 Apr '99

hi folks, first off, thanks to the people who offered quick, helpful responses to my question yesterday. ok, i'm converted. i've started implementing in zope. i have a relational database of about 8 tables. it is used for a registry of trainings and trainers. we have ten centers that will offer trainings. each center needs a publicly accessible home page where people can search on data in the database. also, each center needs a management section, where they can insert/edit/delete data and more. this section is restricted to certain validated users. my question is how to structure this in zope. i started by creating a centers folder, and a subfolder for each center. i plan to place common DTML docs and SQL methods in the centers folder, letting each center acquire them. each center has an ID property, corresponding to its unique ID in the database. i just noticed this morning that this is the same way its done in the budget sample application in the HOWTO section. i must be going in the right direction. i expect to have a number of DTML documents that are access restricted. for organizational clarity and ease of managing the permissions, i'd like to put them in a folder. but if i put them in a folder in the centers folder, then they are parallel to the individual centers and can't be acquired. does this mean i'm stuck putting them all in the centers folder? any suggestions? lets say i put a DTML document called dtViewTrainings in the centers directory. it uses a SQL method and an ID property to get trainings from the database. so the user views http://.../centers/roswell/dtViewTrainings and the ID is acquired from the roswell folder. everything's ok. but what if they browse to http://..centers/dtViewTrainings. there's an error because ID is not defined. that's fine, because the request makes no sense. but is this problem? it just kind of bugs me that the user could browse to this URL and get a meaningless error. thanks in advance for any help, -scott ----- Scott Lewis Baltic Avenue Productions csl(a)balticave.com

DTML style & indentation
by Jordan B. Baker 26 Apr '99

26 Apr '99

Hi all: I am writing a DTML editing mode for emacs and I am curious about ideas for indentation style. It it, and should it be as simple as making a new line have the same indentation as the preceding DTML line, and the tab key just adding one level of indentation to this? If anyone has any thoughts on this please let me know as I am planning to make a preliminary release this week. Thanks, ----- Jordan B.

I think your initial idea is great to start with... After playing with it maybe people will have other bells and features but I for one think the above is a fine start... --Rob

[off topic] question?
by Tom Deprez 26 Apr '99

26 Apr '99

Hi, Another question to all you Python programmers. To tell you the truth, I never heard about Python before I heard of Zope! I knew of Java. Do, it looks like Python is older then Java... How comes that Python is not so popular like Java (or not so known in Windows environment)? Like Java, Python is multi-platform. It can work on Windows as on Unix as on .... Are there any fundamental differences between Python and Java? I see Python has it's Java module (JPython) also... So, I don't get it... Why is Java so popular, while Python seems to be the same and is born before Java... Can somebody give me a easy explenation? Thanks, Tom.
