title: A relational database shared by an android app and a website - the easy way
body: <p>I have a project where I will develop an android application and a website. They both should share the same database.
  I am trying to explore all the options and I am really confused.</p>
  
  <p>Here are my requirements:
  1- I need an extremely simple and <strong>EASY</strong> way. I am not trying to learn; I am just trying to get things done.</p>
  
  <p>2- The database design includes relationships and foreign keys. Therefore, I need a <strong>relational</strong> database.</p>
  
  <p>3- The <strong>users</strong> of the android app are <strong>limited</strong>; as it is not an app that will be on the store. And the <strong>rate</strong> of querying the database is <strong>not extensive</strong>, but the data stored will continuously increase. So, I guess <strong>scalability</strong> is important.</p>
  
  <p>4- I do not have complex data types. Probably just text and numbers, although storing images would be nice, too.</p>
  
  <p>5- I also want to mention that push notifications are needed.</p>
  
  <p>I appreciate if you can provide me with <strong>examples</strong> for the option you recommend. I need to start as soon as possible.</p>
  
  <p>Thank you</p>
