The Access team is proud to introduce the Access 2013 public preview, which will make it easier than ever for everyday people to organize the data in their lives and businesses using Access apps. On this blog, you'll be able to learn about the improvements included in this new release.
Access has always been a great tool to help you organize and run a small business or a team. This release focuses on bringing Access databases to the web, making them more useful than ever. Your database can be hosted by Microsoft through Office 365 and securely accessed from any tablet or computer—even if the device doesn't have Access installed.
Getting started is easier, too, taking just 60 seconds to get your first Access app up and running. With little or no additional effort, you'll end up with a finished app that is both functional and beautiful—automatically—thanks to an enhanced user interface. Finally, we've made some big improvements under the covers to make your apps faster and more extensible. Your data is now stored in a full-fledged SQL Server database. When Microsoft hosts your database in the cloud, we'll use SQL Azure; when you host it yourself on your network, you can use SQL Server 2012. Advanced users will love the fact that they can directly connect to SQL Server with familiar tools for powerful analysis and integration.
Here's a peek of some of the things we'll be talking about:
