Hi,
I think you should try to have an open discussion with a Dynamics NAV partner to find out what you want to buy and what is it can they sell.
1- Does Nav come with BI tools and database ? if not ,is there third party company for MS BI tools and Database For NAV
A: yes; yes. My company recommends Bi4Dynamics for companies needing Bi tools and ready made reports.
2- What kind of Human resources we need in order to support the product after implementation.
My customers in the UK tend to be small companies with less than 50 employees. They usually have 1 or 2 power users, typically someone like a finance manager and an operations manager who "own" the NAV project in the company. These guys are champions of Dynamics NAV, forming a link between the company and the NAV partner chosen for the implementation.
3- what is the Licence price per user and how much the cost for annual support will be ?
The license prices are set by Microsoft and vary by country, like Nev said. The support provision will depend on the implementation partner you choose and the overall complexity of your NAV project. From memory, I'd say that all companies using NAV here have some sort of support plan, to ensure that when the power user has a question they can't answer there is always someone who can help out.
Hope this helps.
