Overview

Are you looking for one go-to place to learn Low level design in a structured and practice-oriented way? You are at the right place.

Designing Object oriented design or Low level design isn't just a skill; it's an art. Mastering it means not only knowing the concepts but applying them with clarity and confidence, especially in the interviews. And that clarity and confidence come from planning, learning and practising which is exactly I am going to help you with in this course.

What is Low-Level System Design?

Imagine you have been asked to build a city. What would you do first? At a high level, you would sketch roads, schools, and where hospitals should be constructed, that's high-level design - Big picture.

Now, as an engineer, you need to build the city from that sketch, and you should decide on how wide a road should be and how traffic lights talk to each other. What materials should go into bridges, how to connect underground cables to each house, and the list goes on. Now you are thinking about minute details and the implementation level. That's low-level design.

In the software development process, low-level design is a step where vision turns into reality with actual building blocks, which are classes, their properties and the relationship between the objects, how they communicate with each other.

In the next section, we will go through the structure of this course.
