Object Oriented Programming to Data Oriented Programming

Description

After seeing many talks on Data Oriented Programming but few examples on how to actually get started with it I decided to make this repo. The goal is to provide easy to digest examples in OOP as well as DOP.

Running

Go

   cd go

Tests

   go test ./...

Benchmarks

  go test ./... -bench=. -benchmem

Rust

 cd rust

TODO

• Go Examples
• Rust Examples
• Zig Examples
• C++ Examples
• Others (Kotlin, Typescript, Java, C#)?
• Real-World Examples in each language (Web Server, CLI, etc possibly)

oop-to-dop's Issues

Add Concurrent Versions

It would be cool to have a concurrent version of each function, along with benchmarks, for both oop and dod.

Add Delete to Go

Want to have full CRUD capabilities for both OOP and DOP sides along with benchmarks to go with that.

Rust Optimizations

Rust DOD can still be optimized further, changes were made to the Posts but things can also be done to Author to improve over all performance even more.

Benchmark Config

Add a config file for benchmarks so that each set of benchmarks across all languages use the same values vs manually hard coding the values in per bench.

Add Rust Implementation

Add the same implementations for both oop style and dod style in Rust.

Go Add Unit Tests

Need to ensure the output is what I expect, so need to write unit tests for each function of the Dop and Oop packages.

Look into adding iai for rust fine grained benching

Github Actions

Setup github actions to at least run tests before allowing a PR merge.

Zig Implementation

Add an implementation in Zig to match the Go and Rust implementations
