Oh, weel. Earlier you wrote: "Im working on a FE (content) Plugin.  The 
user should be able to enter data in the plugin form", so I assumed that 
form is uploaded in FE!

Absolutely right.

Sure. What you need is to use one of hook inside TCEmain. TCEmain is 
where all BE data is processed. There is a function named 
process_datamap(). It includes several hook. Extension can use them to 
pre-, post- or reprocess the data. So when your hook is called, you just 
postprocess xml file and fill your tables.
