Read from sap tables

Hello,

I want to read data from sap tables (e.g. mm01). Can you get me some tutorials for that? And can you tell me where I can find the specific name of a sap table, that I need to read from it (I guess using a SELECT statement)? Maybe you know some example code that could help me out, cause in my abap basics book I didn't find a chapter about getting data from sap standard tables.

thank you.
