Is there a way that we can connect an Android application to a central database server (e.g. MSSQLServer 2008)?
I have a MySQL database that is accessed by both webs
An other approach, musch simpler than Web Service, is to use a Virtual JDBC Driver that uses a three-tier architecture: your JDBC code is sent through HTTP to a remote Servlet that filters the JDBC code (configuration & security) before passing it to the SQL Server JDBC Driver. The result is sent you back through HTTP. There are some free software that use this technique. Just Google "Android JDBC Driver over HTTP".
