Creating Sales order using Business Connector C# (C Sharp)

As the title says, I have to create the Sales order using Business connector and C#. I am able to connect AX using business connector but unable to find any help that how can I create a sales order.  I don't know which of the tables will be used and what are the fields which should be taken care of. I am using MS Dynamics AX 2012.

If any body can help?

Thanks in advance,
