databases, intro, relational, Access tutorial

some INTRO resources on databases (database management systems, DMBS) especially the so called relational databases
- tutorial-like resources

1. databasics from scratch - instructional, very understandable (at geekgirls.com ....???)

2. types of databases -
flat spreadsheet / hierarchical / relational / object oriented
- a brief (minimal) theoretical intro with examples of structure and questions/queries - also (Funnel 2007, McGill Uni)

3. intro to Access - (basic relational db available as part of MS Office)
very instructional TUTORIAL - really click-by-click intro into designing creating, viewing, querying a relational database. (holowczak from Baruch College CUNY) with multiple screenshots.

4. designing and creating relational database - course/tutorial - looks comprehensible with multiple figures to describe problems with designing db, however some links broken (Newcastle 2004)
also some useful guides on software by administrators at Newcastle
eg access, excel, word, spss.
check using ACCESS and SPSS

5. Dilip´s brief intro to relationdal db (1998), schemes, screenshots + some syntax.
