Converting to Drupal

After reading as much as I could find about managing relationships - cck node references, views, taxonomy, other modules, etc - I still haven't been able to get a solution that works in practice. I know exactly how I'd do this if I were working solely with SQL and PHP, but, of course, I want to work within the system.

Here's basically what I have:

Collection of node As that require flickr style tags.

Node Bs can have any number of node As, and node As can be added to any number of Node Bs.

Simple, right? If this were sql, I would have this:

table A (
id
name
etc
)

table B (
id
name
etc
)

table A_B (
id
A_id
B_id
)

The A_B table would management my relationships for me. What is the best way to accomplish this in Drupal? Are there any 'best practices' (naming conventions, modules to use, whatever) for this type of situation? How would *you* do this? I've tried (unsuccessfully) to get cck node references working. Sorry for asking such a basic question. :)

Additional details:

If it helps, here's what I'm actually trying to do.

1) Create a custom content type "Media" that accepts a file upload of a picture, swf, or movie and allows the user to add tags (terms, whatever).

Hi

I'm a complete newbie to Drupal. I am looking to build a new site with Joomla but the ecommerce extensions just don't cut it. I have also posted this over at the Ubercart forum - I need to get some answers quickly as I've lost so much time going down the Joomla path.

I want to create an integrated company web site with shopping cart. My requirements are a litte different from normal in that the site sells license codes to activate software, rather than physical products or even downloadable products. These license codes are emailed to customer after payment.

I've read through a lot of these forums but I'm still unsure if Drupal/e-Commerce can fulfill my needs.

The requirements for the shopping cart are:
1. All customers must register with site before purchasing ie. they have to log-in before making an order
2. Bypass entering of shipping details - not required.
3. Ability to "sell" free trial licenses - customer still needs to go through ordering process and checkout.
4. Bundled products eg Prod A $100, Prod B $100, Special bundle @ $150.
Support for WorldPay payment system.
5. Discounts specific to one customer, or all customers.
6. Invoice generation BEFORE purchase - this is a pro-forma invoice required by some companies before they make a purchase.

I have two different versions of phpmyadmin. With each I am exporting data to sql format. One backup used the asc char '10' as end of line character, but the other uses asc '0'. The settings for the type of backup appear to be the same in each case, does anybody know what accounts for this difference? ( I am capturing data from these sql backup files so I would like to always have a standard end of line indicator )

Thanks!

Hello everybody!

I would like to convert my internet site to Drupal 6. The old site was based on an proprietary CMS on base PHP and MySQL.
I have some functions like News, Guestbook and photo galleries, which I would like to take over into the new Drupal system.
I plan to use CCK-Content Types with similar fields like in the old CMS.

What is the best way for the migration, if I don't want to type in everything manually in Drupal or using cut'n'paste?

Hello,

I am working with a small nonprofit organization helping them migrate an old static/piecemeal site into a CMS. We are quite confident that Drupal is the right tool for the job, and I already have intermediate Drupal experience. We have mapped out most of the necessary specifics for their new Drupal framework, and related content migration processes, but there is one element from their current setup that I am not quite sure how to handle with Drupal, and I am seeking any insights I can find.

Their current site has a feature/section called the "payroll database", which is a simple listing of salary information for various government offices (made available by the Freedom of Information Act and part of their mission to encourage transparency in government). Site visitors can view, in a small table, a listing of salary details for government employees based on their office (each row contains "employee", "position", "salary", etc. headings). Currently this is powered by a custom ASP script and a MSSQL database. They populate the actual data via excel or access files provided by government.

its actually a simple thing ... i would just need some help by Permissions and groupsets .. (data in the usertable)

i want users to "automatically" getting signed up on the drupal system if they signing up on the control panel.
(this is done by a admin anyway)

so i simply do md5 the password and make a insert into the user table of drupal.

all works so far .. exept the permissions and/or groups.

how can i define a default permission set for this kind of users ?
