Master MongoDB, the NOSQL leader with Clarity and Confidence

Explore MongoDB queries with comparison and logical operators, find with projection, and apply limit, skip, sort, as well as insert, update (set and increment), and delete operations.

Master MongoDB update queries by selecting matching documents, applying updates with the $set operator to modify fields, and using update one, update many, and upsert options for insert-or-update behavior.

Explore delete queries in MongoDB by using delete one for a single document, delete many for multiple documents, or the remove option for matching records.

Explore arrays in MongoDB by querying array fields (scores, grades) and updating arrays with push and addToSet, including handling single and multiple document updates and ensuring unique values.

Master MongoDB aggregation basics with pipeline, match, group, and distinct, and compare map-reduce versus aggregation for efficient data analysis.

Learn MongoDB replication by bootstrapping a primary and secondary, configuring a replica set, and validating reads, writes, and automatic failover through a simple demo.

Explore mapreduce in MongoDB with a simple map and reduce workflow, driven by a query and output stage, and see how it compares to aggregation.

Explore how MongoDB indexing, including default _id indexing, single and compound indexes, and create drop reindex operations, boosts find performance while noting trade-offs for inserts and updates.

Explore how TTL indexes in MongoDB automatically remove documents after a set number of seconds, demonstrated by creating an index on created_at with expireAfterSeconds of 100.

Learn the difference between save and insert in MongoDB, where insert creates a new document or errors on duplicates, while save updates or replaces an existing document using its id.

Master the MongoDB Java workflow: add Maven dependencies, connect with the Mongo driver, insert and find documents in collections, and perform tasks like drop database, create index, and run commands.

Install the MongoDB extension for PHP using composer or a direct download, then place the file in the extension directory and update php.ini to enable it, avoiding the legacy driver.

Master a MongoDB workflow with PHP: create databases and collections, insert, find with sorts and projections, update and delete, and drop collections or databases.

This lecture covers bulk operations in MongoDB with Node.js, including batch inserts and updates, and demonstrates aggregation pipelines with match, project, and group, plus file upload and read.
