Designing Data-Intensive Applications - Chapter 2 - Data Models and Query Languages

Designing Data-Intensive Applications - Chapter 2 - Data Models and Query Languages

Earlier this year the book club of our company has studied excellent book:

Martin Kleppmann - Designing Data-Intensive Applications

This is the best book I have read about building complex scalable software systems. 💪

As usually I prepared an overview and mind-map.

Chapter 2:

  • What is data model.
  • Different relations between the data.
  • Relational, Document, Graph data models. Which one is better and when.
  • Schema-on-write, schema-on-read (schemaless). Data locality.
  • Query languages: imperative, declarative, MapReduce. Why NoSQL is reinventing SQL 😀
  • Storing graphs. Query languages for graphs: Cypher, SPARQL, Datalog.
