Conducting Business Analysis role in my internship

Firstly I am asked to restore a database of a Laos project. But I couldn't understand why is it. Then I am asked to study about the database that I have given. Then my supervisor told me that I have to conduct an interview with Laos client about the project that we are going to develop for him. 

There I have to use Skype for video conferencing with Laos client. Actually it will be a great chance for me in my life. Because there I can get the experience of handling foreign customers in my first glance of career life. But now I have some afraid about it, because it is the first experience of meeting clients. 

For collecting the client requirements, I have to have get the knowledge of Financial Accounting. Now a days, I use some inline materials for gaining Accounting knowledge. Accounting Coach.com web site is mostly used by me for achieving that purpose.
