body: <p>Does this kind of design come along with overhead or data redundancy?
  The structure of tables should <strong>remain</strong> able to do <strong>CRUD on tag</strong>, for something like manga/anime tag, allowing specific resources found-able through selection of tags. * representing primary key.</p>
  <pre><code>tag     (tagID*, tagName)
  tagMap  (tagSetID*, tagID*)
  tagSet  (tagSetID*)
  announce    (announceID*, tagSetID, title, content)
  </code></pre>
