What is the use of SDK?

What is the meaning of SDK?
Is SDK can be use to integrate other MS dynamics?Thanks. Very Happy

SDK just means Software Development Kit. In Microsoft lingo, it normally just referes to a library of code or DLLs etc. that can be used to build a bugger application, or to integrate with an existing application.

In the NAV world, it normally realates to things like the C/FRONT c++ library that allows you to write C code that interfaces to the NAV database directly. For example you can use the SDK and NAS to interface directly tot he NAV business logic.

I am not sure where C/FRONT will be though when Web Services are released.
