BDC ...? . ? .. . ? Confused

Question

Hai Dear ABAP Pros..
As far as I know, BDC is used to Transfer data from legacy system to SAP system. I have newly started my career in SAP ABAP & I am the only guy for this company on ABAP & havenot yet worked on BDC yet.
I have gone thru the notes & material I have on BDC. I am confused with what exactly is it, 'coz at some places its given that we have <b>to start with SHDB to record Transaction (How come the Standard Transactions are used & what role do they Play in BDC(transfer data)??)</b> & in one Book its given as below & recording is not mentioned any where:
<b>1.To identify the Screens of the Transaction that the Program will Process.
2.To build the BDC table that will be used to submit the data to SAP.
3.To submit the to the BDC table to the system in Batch mode or as a single transaction thru CALL TRANSACTION command.</b>
Plzz help me out by clearing my doubts. If possible & if U have some docs or material or some real programs or exercises with solutions then Plzz forward them to "[email protected]". ..
Would higly appreciate & be thatnkful to U.
Thanks in advance.
Regards.
