A CSS Unit Deep Dive - Learn CSS Units & When To Use Them
00:00 intro
01:09 Pixel unit
06:15 em & rem
12:10 %, vh, vw
14:12 ch unit
Thereβs at least 40+ different length units in the CSS specification and initially I was going to go over literally each one of them until I realized how silly of an idea that was. The truth is, many of these units should either not be used at all or are rarely used for web design.

Advanced Queries: Use $and, $or, $not, and $nor. Query arrays and embedded documents.
Projections: Return specific fields using projections in queries.
4. Indexes
Purpose of Indexes: Speed up queries and optimize performance.
Create and Manage Indexes: Single field, compound, and text indexes.
Understand Index Impact: Use the explain() method to analyze query performance.
5. Aggregation Framework
Introduction: Understand the pipeline approach in aggregation.
Basic Stages: $match, $group, $sort, $limit, $project, and $lookup.
Advanced Stages: $unwind, $addFields, $replaceRoot, and $facet.
6. Data Modeling
Schema Design: Differences between embedding and referencing documents.
Relationships: One-to-One, One-to-Many, and Many-to-Many relationships.
Best Practices: Design schemas for scalability and performance.
7. Transactions
Multi-Document Transactions: Implement ACID transactions in MongoDB.
Use Cases: When to use transactions in NoSQL.
8. Working with MongoDB in Applications
MongoDB Drivers: Integrate MongoDB with programming languages like Node.js (Mongoose), Python (PyMongo), and Java.
CRUD Operations in Code: Perform database operations using drivers.
9. Administration and Optimization
Backup and Restore: Use mongodump and mongorestore for backups.
Performance Optimization: Optimize queries, manage indexes, and shard data for horizontal scaling.
Security: Configure authentication, roles, and encryption for secure access.
10. Build Projects
Beginner: Create a basic CRUD app (e.g., contact manager).
Intermediate: Build an inventory management system or blog backend.
Advanced: Design a scalable social media backend with user posts, comments, and likes.
Deploy on MongoDB Atlas or integrate with cloud platforms.
