Hi boggyboy,
First of all: welcome to umbraco.
Answer to your question: umbraco comes with a bunch of data types already available. A list of available datatypes can be found in the 'Developer' section, under the 'Data Types' node.
It's even possible to create custom datatypes.
You see, umbraco is all about extensibility.
Good luck on your umbraco journey and feel free to ask more questions when moving along.
Regards,
/Dirk
