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.

TOP REVIEWS FROM JSON AND NATURAL LANGUAGE PROCESSING IN POSTGRESQL
Its awesome I can use it in my software development
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 :)
Week 4 was a titbit challenging, but I figure it out. On to the next one. Lol
Could use some more examples on WHY we need JSON in a SQL setup
About the PostgreSQL for Everybody Specialization
Across these four courses, you’ll learn how to use the PostgreSQL database and explore topics ranging from database design to database architecture and deployment. You’ll also compare and contrast SQL and NoSQL approaches to database design. The skills in this course will be useful to learners doing data mining or application development.
