Mathematica and MySQL work together beautifully. My connections look 
like this:

Needs["DatabaseLink`"];

jpDB = OpenSQLConnection[
    JDBC["MySQL(Connector/J)", "localhost:3306/whateverdb"],
    Username -> "whatevername", Password -> "whateverpass"];

SQLConnections[]
(* just to check that I have a good connection. If I do, it responds 
with something like "{SQLConnection[1, "Open", "Catalog" -> "whateverdb",
   "TransactionIsolationLevel" -> "RepeatableRead"]}"  *)

I generally design the tables with MySQL Workbench, and then use 
SQLInsert or SQLExecute to add data, and SQLSelect or SQLExecute to 
retrieve it. I'm not sure a detailed example would help much, as it 
would depend on the structure of your database, which is surely 
different from mine.

Good luck,

Michael
