I'm obviously not talking about a full solution, but just a good starting point for common applications for software architects. It could be for a CMS, e-commerce storefront, address book, etc. A UML diagram is not essential, but a table schema with data types in the least. Thanks!
Check out the Library of Free Data Models from DatabaseAnswers.org -- might be a good starting point. I can't vouch for the quality, but there is a lot here...
Open source?
DB-UML might work for you.
EDIT:
Oh! The MySQL Workbench is good.
The mondial database. Is used for learning about DBMSs. If you need something quick and dirty to bang around.
try this one... database design document template.
very good and usefull template.
but it isnt free.. you have to buy it.. :(

Is there any easy resource available online or a book which would allow a complete newbie how the database normalization process works and what one should do to perform the transformations on a given database leading it from 1NF to 5NF through all the in-between?
From my research, it seems that the Wikipedia article seems to be the closest to what I'm looking for but is there anything even easier?
This highly depends upon your taste. But I have found that the course in class2go offered by Stanford is quite good. It has a fairly good explanation of normalization up until NF4. For a complete newbie I think this would be quite useful.
You have to sign up but the material is supposed to be there:

Also have you seen this?

Does anyone know of a good web-based GUI I could use for database design? It is going painfully slow in Photoshop.
You can use MySQL Workbench to do this. There are many web-based apps as well. http://wb.mysql.com/
Try this web-based designer
Just had occasion to use this earlier today: http://www.dbvis.com/
Java/uses JDBC drivers so widely compatible
Produces reasonably pretty relationship diagrams
The free version is still pretty capable, and the cost is eminently reasonable
EDIT: Ah, not web-based, but...somethings you really can't fit into that box very well.

This can be community wiki.
I'm looking for a simple, multi-platform, free database browser (ODBC,etc). This is for those times when I want to interface with a database, and just need a simple way to quickly see what the heck is in it. Doesn't need to support any vendor-specific features.
Too much junk out there and I don't want to play with these things all day. What do you use?
I like SqlDbx - the personal edition is free. It supports most of the major databases, and the built in intellisense is useful for queries.
Dbvisualizer has a free version http://www.dbvis.com/products/dbvis/download/

I consider to use some NoSQL database in one of my project. Do you know some good starting points for a newbie in this topic?
Pick your particular "NoSQL" database first -- or at least type of "NoSQL" -- I'm going with the assumption that there is a reason why you want "NoSQL". Do you need object graph traversal? Explicit distributed clustering? Fast write/append? Dumb key/value associations? The selection should be based off more than a "I want something NoSQL" as different approaches can offer significant advantages (along with significant drawbacks) :-)
And, as often, google/wikipedia are a good place to start:
http://en.wikipedia.org/wiki/NoSQL
http://nosql-database.org/ has a long list of alternative databases, grouped in categories by type of technology. It has links to each product's website, lists of books, and forums, news, etc. about NoSQL.
Also see http://nosqlsummer.org/city/krakow. This is the Kraków chapter of a reading club for studying NoSQL concepts. I see from your profile that you live in Kraków.

I am a java developer and i will be interviewing sybase dbas along with my boss.
I know some basic stuff about sybase.
Iam looking for good interview questions that i can ask for a sybase dba.
they will be having a min of 4 years of experience.
I am looking for them to have really good knowledge in performance and tuning related areas like how to measure database performance and suggest ways to improve database design or sybase configuration etc.
Interview is through telephone.
Help much appreciated.
BR
This isn't a question, really, but I would set up a (possibly virtual) machine with a large-ish Sybase database on it and then set about screwing it up as badly as I could, and then sit the DBA candidate down in front of it and see what they can do with it.
I plan to do this for my next set of C# candidates, since I place a great deal of value on debugging ability and I can't think of any better way than testing it directly. As a programmer, I would love to do this if I were being interviewed myself. It's sure to weed out at least the people who know less than you do.
This is Microsoft focused but you should be able to glean something from it.
