Compare traditional databases and vector databases to understand exact, Boolean queries and deterministic results versus similarity-based, probabilistic ranking using dense meaning vectors.
Create and manage databases with Python classes, including setting up the database, adding tables and elements, and viewing tables via a reusable SQL classes script.
Install MongoDB Atlas and Compass for the database and data exploration. Add Python pip packages, Node.js and npm, OpenAI and HuggingFace SDKs, and Atlas Search for semantic retrieval.
Explore basic MongoDB operations in the mongo shell, including creating databases and collections, inserting documents, querying with conditions and operators like $gt, projecting fields, sorting, and limiting results.
Explore how to model relationships in MongoDB, including one-to-one, one-to-many, and many-to-many, to optimize performance and data loading.
Part 6 of the MongoDB tutorial explains how indexing speeds queries by adding indexes on author, tags, and the body text, including text search with $text and $search.
