How to Develop Android Database Applications in RAD Studio XE5

Not so long ago, in RAD Studio XE5 there was introduced support for Android application development. On the Internet there can be found a lot of information about Android application development in Delphi XE5, but when it comes to development of database applications, it becomes much more difficult.
