title: Multiple application using one database?
body: <p>Think Design: I have many applications that share the same user database! Other tables are shared as well such as user activity logs, purchases etc</p>
  
  <p>1) Anyways my question is if I was to make all applications just use 1 database for everything! Would I have any problems with scalability? Or any other problem doing this? Is it better to have 1 database ? ? Or worst?</p>
  
  <p>2) Or should I just let every application have their own database, then use web service to share the common tables between the applications?</p>
