Which database should I use for a medium SaaS CRM? nosql or relational database?
Oracle
Sql Server
CouchDB
etc.
Any suggestions?
Wow, not giving us much to go on there. There are many good DBMS systems out there from the relational to document based to object based. One of the reasons there are so many is they each have advantages and disadvantages in different application scenarios. With so little to go on I'd say use the one you're familiar with unless there's a driving reason to use another.
MYSQL would be a great idea as it is open source and is gaining acceptance in enterprise also.

What is the best database to start learning stored procedures.
Taking into account that each database has its own syntax. Like Postgresql has functions, SyBase, Oracle, MS SQL, DB2 has some sophisticated procedures..
Is there is some db, you think is good one to use, let's say, for students to demonstrate the principles, knowing which, the students could jump to some specific database without big problems? Something that stays at the middle of the popular set of dbs.
As you know that almost all modern DBMS support stored procedures and vary in syntax. So that's pretty much the personnel choice. But the most easy to use DBMS is MySQL. That can be comparatively more helpful then Oracle, MSSQL or DB2 especially for new students.

I am now struggling to find a best database for the following purpose:
1. Store the online data every 0.1 second!
2. Easy to access the data in the database
3. Compatible for windows system
4. No need to be OpenSource Solution
Any suggestions?
Well there is alot of nosql db systems, most simplest for me are redis and mongodb.
I use redis for highload apps, and mongodb for easier access to data (if you came from sql world). Both have windows versions, both open sourced.

I've recently been tasked with doing some "big data" stuff with an existing Oracle database. The relevant table has 300 million entries, and is ridiculously slow. Are there any good books out there that explain how various options in the DB construction effect the algorithmic scaling (O(n), etc) of various queries? And how different query operations themselves effect scalings?
I'd prefer to get an understanding of how the underlying algorithms work rather than just ad hoc suggestions.
Jonathan Lewis' book on Cost-Based Oracle Fundamentals may be what you're looking for.
For particular techniques regarding querying large data sets the Oracle Data Warehousing documentation would be a good start.

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/
