Today's Lesson: Searching Structured Data

Today, we are learning about searching through structured data.

A library catalogue is an excellent example of structured data.
Each item is associated with a fixed set of fields, such as the author, title, keywords, and call number.
You can select which field you want, and search for the occurrence of literal strings within that field.
