title: how to define relationship between InfluxDB measurements (tables)
body: <p><strong>Need some explaination</strong>, </p>
  
  <ul>
  <li>How to define relation b/w (InfluxDB) time series database?</li>
  <li>Like N-hibernate support multiple databases, we can shift from mySQL to SQL 
  easy. Does Time series database have any similar ORM solution?</li>
  <li>I have worked on relational database in which we use primary key and foreign keys to define relation between tables, and there different type relation (One-one, one-to-many, many-to-many).</li>
  <li>Can we define similar relationship into InfluxDB? if, not how can we acheive relationship between tables (measurements)?</li>
  </ul>
  
  <p>Meanwhile, InfluxDB provide us Tag keys (indexed), should we use these to define relationship between tables or measurements?</p>
