Course Description
MongoDB is a tool to explore data structured as you see fit. As a NoSQL database, it doesn't follow the strict relational format imposed by SQL. By providing capabilities that typically require adding layers to SQL, it collapses complexity. With dynamic schema, you can handle vastly different data together and consolidate analytics. The flexibility of MongoDB empowers you to keep improving and fix issues as your requirements evolve. In this course, you will learn the MongoDB language and apply it to search and analytics. Working with unprocessed data from the official nobelprize.org API, you will explore and answer questions about Nobel Laureates and prizes.

Flexibly Structured Data
FreeThis chapter is about getting a bird's-eye view of the Nobel Prize data's structure. You will relate MongoDB documents, collections, and databases to JSON and Python types. You'll then use filters, operators, and dot notation to explore substructure.

Working with Distinct Values and Sets
Now you have a sense of the data's structure. This chapter is about dipping your toes into the pools of values for various fields. You'll collect distinct values, test for membership in sets, and match values to patterns.

Get Only What You Need, and Fast
You can now query collections with ease and collect documents to examine and analyze with Python. But this process is sometimes slow and onerous for large collections and documents. This chapter is about various ways to speed up and simplify that process.

Aggregation Pipelines: Let the Server Do It For You
You've used projection, sorting, indexing, and limits to speed up data fetching. But there are still annoying performance bottlenecks in your analysis pipelines. You still need to fetch a ton of data. Thus, network bandwidth and downstream processing and memory capacity still impact performance. This chapter is about using MongoDB to perform aggregations for you on the server.
Intro to Aggregation50 xpSequencing stages50 xpAggregating a few individuals' country data100 xpPassing the aggregation baton to Python100 xpAggregation Operators and Grouping50 xpField Paths and Sets50 xpOrganizing prizes100 xpGap years, aggregated100 xpZoom into Array Fields50 xpEmbedding aggregation expressions50 xpHere and elsewhere100 xpCountries of birth by prize category100 xpSomething Extra: $addFields to Aid Analysis50 xp"...it's the life in your years"50 xpHow many prizes were awarded to immigrants?100 xpRefinement: filter out "unaffiliated" people100 xpWrap-Up50 xp
