Within this course, you’ll learn about how PostgreSQL creates and uses inverted indexes for JSON and natural language content. We will use various sources of data for our databases, including access to an online API and spidering its data and storing the data in a JSON column in PostgreSQL. Students will explore how full-text inverted indexes are structured. Students will build their own inverted indexes and then make use of PostgreSQL built-in capabilities to support full-text indexes.

来自JSON AND NATURAL LANGUAGE PROCESSING IN POSTGRESQL的热门评论
Its awesome I can use it in my software development
Could use some more examples on WHY we need JSON in a SQL setup
Week 3 and week 4 instructions can be a bit ambiguous, however the discussion form posts helped a lot.
This course teaches some niche applications. Not sure if i'll ever have to use them, but good to know what to look for in case it ever comes up at work :)
