What is the most practical way to implement camera/viewport to a 2D-game?

I've read, that I should store the object world position instead of position relative to the screen?

Current situation:

I have implemented a simple 2D-game where I load objects and levels from XML-files. Currently the level XML-file looks like this. All objects have a 2d-vector "position" storing their current location on the screen.

What I want it to be:

I made a picture to explain what I'm trying to achieve. In the picture:

• Camera is either 800x600 or 640x480
• Blocks and sprites are 16x16 pixels.
• World size may vary
• The coordinates probably should be normalized relative to the world, not to the screen?
• Viewport position relative to player's x, y and moves when the player reaches camera dead zone (similar to this).

I'm asking pseudo examples / articles, but if you need to know what I'm using for the development: SDL & C/C++.

<map>
   <tile obj="ground" x="0" y="555" />
   <tile obj="ground" x="16" y="555" />
   <tile obj="ground" x="32" y="555" />
   ...
</map>
