body: <p>I have table with created on it materialized view log:</p>
  
  <pre><code>create table T1(A number primary key);
  create materialized view log on T1 with primary key;
  </code></pre>
  
  <p>Oracle additionally creates two tables for materialized view logs:</p>
  
  <pre><code>select TABLE_NAME from USER_TABLES
  
  |T1       |
  |MLOG$_T1 |
  |RUPD$_T1 |
  </code></pre>
  
  <p>How to determine that <code>RUPD$_T1</code> table is a table with the mview logs for <code>T1</code>?</p>
  
  <p>I can determine this for <code>MLOG$_T1</code>:</p>
  
  <pre><code>select MASTER, LOG_TABLE from USER_MVIEW_LOGS
  
  |T1       |MLOG$_T1 |
  </code></pre>
  
  <p>But where to find a reference to the table <code>RUPD$_T1</code>?</p>
