title: Convert calls to read and write YAML data to MySQL
body: <p>I am editing Java code which stores data in a YAML file, but I need to make it use MySQL instead, but I'm not sure how to go about doing this. The code makes request to read and write data such as <code>SQLset("top.middle.nameleaf", "Joe")</code> or <code>SQLget("top.middle.ageleaf")</code>. These functions are defined by me. This would be simple with YAML, but I'm not sure how to implement this with SQL. Thanks in advance. Another thing is that if <code>top.middle</code> was set to null then <code>top.middle.nameleaf</code> would be removed, like it would in YAML.</p>
