This is what Microsoft should have done some versions back and have an Access database easily uploaded to the web – a big CHEER please!!!
You do need to have web services in place and Microsoft Sharepoint is the obvious choice here. Ryan (the author of this video) makes it look easy – and it is.
Remember, the web version and its functionality will never be as rich as the LAN version (client interface) and therefore you still need to design a good Access database system as its back-end.
Thanks Ryan for the heads up
