BDC allows you to perform database updates in the background using standard SAP transactions.
The resultant entries will be as if the user had manually entered the data via SAP. This means
that you do not bypass any of the standard SAP consistency checks, authorisations etc.
There are two main methods of ABAP BDC, these are Call Transaction and Batch Input.
Other methods of update include Direct update, Idoc and BAPI.
