title: Data Mapping between two different Database Schemas
body: <p>I have to design a system with an sql database whose work is to get data from different databases which may be in another database such as mysql or oracle etc. Then the system will map the attributes of that database with my database schema and store them..
  Example reference link: <a href="https://msdn.microsoft.com/en-us/library/aa728893(v=vs.71).aspx" rel="nofollow">https://msdn.microsoft.com/en-us/library/aa728893(v=vs.71).aspx</a>
  Since I am new, I can't attach images which is why I am providing links.</p>
  
  <p>All my searches end up with getting the mapping tools but what actually I want is how to create that tool myself. 
  I am not a professional but a little push will be enough for me and highly appreciated. Thanks in advance. </p>
