Converting to Drupal

I'm new to DRUPAL and need some guidance on which modules to use.

I wish to transfer a quite simple existing site on to DRUPAL

The current setup is english language only classic asp with just one aspx page.
The 2 small data bases are flat file csv, ie not really a database in the modern sense.

The current functionality is elementary.

1) One Form to collect minimal data to create a user profile and issue a password, user ID is email address.
2) Logon goes to a TABBED web page
2.1) change pass and update user profiles
2.2) Collect some data with classic asp page, submit returns an aspx page with a barcode to be printed.
2.3) Upload a File collecting data concerning where to deliver the file.

Additional fumctionality
Ability to access via a customer number or email address
Additional TAB to contain a table listing files and delivery details in a table

Behind the web pages are 16 daemons written in VB6 which process input from the above web pages, plus they extract/obtain

data from other sources. These data are also used to update the flat-file DATABASE.

The main issue with the changeover is that I do not immediately have the resources to change the VB6 daemons to run against

a 'proper' database, so I must adapt the data access module of drupal to use the current flat file database.

My route map is as follows.

Hello,

I am working on converting (and improving) my website (www.wiki-babel.org) from mediawiki to Drupal, as it seems the functionalities I want to add would be much easier to develop on Drupal than on the existing system. As it's my first Drupal attempt, I'm trying to get some advice on how to do the following:
I have content types 'lesson' and 'sentence', each with several fields. Sentences can live on their own, but can also be included in lessons.
A well known analogy would be a catalogue of products (sentences) which can be included in invoices (lessons), with quantities for each invoice line (I need to qualify each line with several fields). Lines are also ordered in my case. All of this must support revisions (both sentences, and lessons) like a wiki would.
The added difficulty is that sentences (products) can be created/updated while changing a lesson (invoice).

I've read quite a bit, explored several modules and options, and now my plan is to create a third content type (or a custom entity) ('line' like 'invoice line') that references both an invoice (lesson) and a product (sentence) (using module references). But that apparently means a fair bit of coding to get revisions to work, corresponding forms, etc...

I have a small group of sites from the same industry and which share much content. All of these sites share a single database and single tables. Table examples follow:

USER:
id -
fname -
lname -
email -
password
etc.

SITE: one record for each site I manage
id -
site_name - stores the site name
theme - used to select a theme
header - stores header text
footer - stores footer text
etc.

I'm not a developer and new to drupal, and I've been trying to import a csv exported from an Access DB using Feeds. I've tried everything and get nothing but errors.

Can anyone lead me in the right direction to get this working. The csv contains a lot html in the body mapping, and that seems to be causing the trouble. Here's my latest error. I've tried separator, text qualifier, etc. It's encoded utf-8:

SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'last_comment_uid' at row 1

Hi, I would like to convert my website from sunlight cms to drupal.

I know how to import articles however I am stuck with importing of users.

The problem is that in sunlight cms the database for password and salt looks like this:

Password | Salt
ae31b78cca21009274344c50ac45bcff | ranyx847

Both are tinytext.

However, only a certain users have Salt, some doesn't e.g. one user have only this for Password field

311d1466788c58771098c874a3add05a

and no Salt value at all.
