Question about MSMQ and SQLite

The Diagnostics and Troubleshooting SCP Study Guide lists section 1.4.11, which says, "Recognize the difference between MSMQ and SQLite". Later in the document where specific URLs are listed where one can find information on each study topic, there is no such link for this topic. 

I googled "compare MSMQ and SQLite" and got no hits. I fact, it seems that "comparing" the two is meaningless. Can anyone tell me what is meant by this study topic and perhaps point me to SolarWinds documentation on the topic?

Thanks for any direction.
