title: Why so few full database schemas sample online?
body: <p>It is a bit strange to me about database schemas sample which I think most of the projects will need to design a database for it. but when I try to find sample online, it is really rare (eg. full database schema for Inventory Management, School Management, HumanResource management). I know that each database design is depends on the project requirement, but I don't think it is much different. </p>
  
  <p>I just wonder why there is so few people kick it online as other source code.</p>
  
  <p>Could anyone pointing me out where to get it or any advice?</p>
  
  <p>Thanks in advance</p>
