Webapplcation and Database in different location.

Hi All,

 

I need some help regarding the below scenario:

I have the web application and database in DMZ zone, now i need to bring database server in our domain but app server will remain in DMZ zone, and we need to connect the database via wcf service like : Web application (fron end) +--> +WCF Sevirce +--> Database.

1. my database is containing transaction and master data.

2. for master data can i use caching ???

 

please let me know the best approche how i will modify the application.

 

Thanks.
