Could someone out there please help me to answer these questions?
Thanks in advance.



1. What aspects of SQL Server allow it to reliably scale up to support
a large global enterprise? And, when does SQL Server reliability
begin to fail?

2. Given a role-based security model and without doing a benchmark,
are there potential performance issues of using a SQL Server database ?
How would this change if more of the security was moved to the
application level or moved to the database?

3. How does SQL Server manage access to data at the record and data
field level?

4. w do support and administration requirements compare between SQL
Server (or MSDE) and Oracle? Consider levels of expertise needed from
central server to desktop implementations.

If you have more specific questions after you've reviewed the
documentation, then feel free to ask. And don't forget that having good
staff, a good design and a good implementation plan is usually far more
important than whether to pick product A or product B.
