3 min readJun 21, 2022

Below are my collection of resources to learn about system design/operating systems related concepts. As I continue on my journey of learning new things, I will keep on adding to this list ! :) Happy Learning !!

p.s. I have created a new post dedicated to “Databases related notes w.r.t system design” — https://svalaks.medium.com/system-design-my-notes-on-database-pros-and-cons-will-keep-updating-151e7be74c4b

Database choices:

Relational database

  • many-to-many relationships
  • data and data relationships need to strictly follow schema
  • consistent transactions are important
  • hard to scale because relationships are hard to partition effectively

Graph database

  • many-to-many relationships (graph structure)
  • fast at following graph edges
  • suited to complex network analytics
  • less mature technology than Relational

Document store

  • isolated documents
  • retrieve by a key
  • documents with different schemas that are easy to update
  • easy to scale

Key-value store / object store

  • opaque values
  • no schema or relationships known to the database
  • very simple operations
  • easy to scale

Column-family database

  • groups related columns for storage (easy to scale)
  • memory effective for sparse data

Search engine database

  • large amounts of unstructured data
  • full text search or fuzzy search service

Time series database

  • data is ordered by time
  • many data streams
  • real time entry ordering functionality
