Sample code is going to be difficult in this stage.

First you need to get basic requirements like:

- how are you going to interface (file pick up from share or (s)ftp(s) / webservice / jdbc ) ?

- what kind of format, flatfile, xml, IDoc ?

- synchronous or asynchronous ?

- are you going to use a middleware solution like SAP PI or TIBCO or is it going to be direct connections between legacy and SAP ?

- frequency of interfacing and size of messages ?

- error handling, queueing and quality of service ( exactly Once , Exactly Once In Order) ?

Once you have these requirements clear you can start thinking about scenario's and after that it will be (sample) code.
