title: Page vs. Extent vs. Segment vs. Tablespace
body: <p>Mysql's Innodb has concepts of page, extent, segment, tablespace but I don't know how they interact with each other. How are they related? What does it mean a tablespace has 16K of pages? How does this relate to the physical rows and is 'pages' something in the memory?</p>
  
  <p>I would assume that Oracle might have the same concept but I'm not sure where to look for it. Is there a good reference / book that talks about this in detail?</p>
