Choosing the Right Database: Understanding Different Data Models and their Pros and Cons [00:02]Choosing the right database model is crucial for app performance and scalability. [02:35] Key-value databases are well-suited for in-memory storage, providing faster responses [05:17] Key value stores are optimized for high performance and low latency applications. [07:56] White columns databases store data in a normalized form [10:22] Cassandra databases offer horizontal scalability and fast writes. [12:48] Document databases, like MongoDB, provide a more convenient way to handle data. [15:24] Document databases offer scalability and easier integration with object-oriented programming, but lack features and integrity [17:53] Normalization is the process of organizing data into separate tables to improve data integrity. [20:07] Different database models have different challenges in complying with all acid properties. [22:16] Graph databases are difficult to model and distribute across multiple nodes.

That was amazing. Thank for you helping me in my prep. This should have way more views. That was the perfect level of detail and the diagrams and animations help solidify the detail you provide. Bravo!

You're amazing bro, thank you so much for making these videos! I'm preparing for a senior engineering interview and haven't been feeling very confident about it. Your videos are really helping me build a framework for understanding things at a more high level. I appreciate your effort. Thanks again!

Hello, I love this video. Perhaps a little feedback. On every of my device, your video audio is so soft. I think it would be nice, if the audio is a bit larger so that I can hear better. Thank you very much.
