<p>Spend most of my time in a db2 environment as a DA/DBA. From time to time I also work with other DBMS such as mysql, psql, mssql.</p>
<p>I have a couple of Db2-utilities at github, that you may or may not find useful:</p>
<p><a href="https://github.com/lelle1234/Db2Utils/" rel="nofollow noreferrer">https://github.com/lelle1234/Db2Utils/</a></p>
<ul>
<li><p>DBParser, creates ddl for a database. Output is supposed to be in topological order</p>
</li>
<li><p>IndexAdvisor, investigates all possible index combinations for a query</p>
</li>
</ul>
