Systems Design and Architecture 🔥

Systems design is the process by which we as engineers make decisions regarding the elements of a complex application. These system elements-- such as the data models and structures, overall architecture, modules and components, and the different interfaces of those components-- have to be carefully contemplated to ensure speed, reliability, and stability down the line.

Databases are a critical component of modern web and native applications. They're used to store, retrieve and manipulate data. They can be found almost anywhere there's a need for storing and accessing large amounts of information.

In this section, we'll get to know databases really well. Starting with some theory, and then moving into building blocks, types of databases, and uses-- you'll learn what you need to use them well in interviews!

This section will consists of briefer architectures of certain products and companies at a higher level. These lessons are intended to get you to start thinking more holistically, before we dive into the deeper calculations and inner workings of complex systems.

Computing systems are composed of software and hardware. For a machine to work, these components need an intermediary to manage the communication between them. Operating system serves this purpose by allowing the user to interact with computer software and hardware.
