My company has decided to move into SharePoint 2010 for data warehousing and for use by many different departments. As it stands I have no experience in SharePoint and am need of some pointers. What I am trying to accomplish is to store all my lists in a single site or site collection to which I will grant the least amount of privileges to and then created other sites or site collections to which my users will actually go and work from. I need to find a way to allow users to access forms and data from the single “Lists” site(collection) and work with that data and have workflows run on that data across different lists. For instance, HR will need an Employees list where they enter employee info. When that is submitted I need it to email me in IT to create accounts and grant that user access, as well as notify Finance of the hire. When HR terms an employee or someone changes roles I need workflows to notify the responsible people to take the required actions, i.e. IT disables the employee’s accounts. Basic can anyone point me to a resource for someone new to SharePoint 2010 to connect lists to a different site or site collection?
