I am developing a database-driven website, intended to be compatible with mobile devices.
I started developing it 5 years ago using .NET / SQL Server, and then layered AJAX on it to arrive at better query response time. However, queries currently run slow, and it's not compatible with mobile devices. It's now time for a re-design, utilizing latest technologies and frameworks.
Are there any particular platforms / frameworks that are currently well suited for database-driven web applications, that also work well on mobile devices?
