This presentation was recorded at GOTO Aarhus 2023. #GOTOcon #GOTOaar https://gotoaarhus.com Yehonathan Sharvit - Author of Data-Oriented programming @viebel RESOURCES https://twitter.com/viebel https://github.com/viebel https://linkedin.com/in/viebel https://blog.klipse.tech ABSTRACT Complexity is one of the main difficulties in the development of successful software systems. Modern programming languages and frameworks make it easy to develop and deploy our code quickly, but as the code base grows, complexity makes it challenging to add new features. Data-Oriented programming is a paradigm that aims at reducing the complexity of information systems such as back-end applications, web services, web workers, and front-end applications by rethinking data. Data-Oriented programming treats data as an immutable value that is manipulated by general-purpose functions. Moreover, data is validated à la carte. In this talk, we illustrate the principles of Data-Oriented programming in the context of a software production system. After attending this talk, you will be able to apply Data-Oriented programming principles in your preferred programming language and reduce the complexity of the systems you build. Takeaways • Apply Data-Oriented Programming principles in your preferred programming language • Apply data validation techniques without using static types • Represent data with immutable data structures • Manipulate data with generic functions [...] TIMECODES 00:00 Intro 01:10 What is complexity? 03:00 Information systems 03:54 Principles of data-oriented programming 05:49 What makes a software system complex? 07:23 Principle No 1: Separate code from data 12:16 Principle No 2: Represent data with generic data structures 22:51 Principle No 3: Do not mutate data 28:42 Immutability in practice 29:42 What about data validation? 36:06 History of data-oriented programming 38:38 Summary 39:17 Outro Read the full abstract here: https://gotoaarhus.com/2023/sessions/2535 RECOMMENDED BOOKS Yehonathan Sharvit • Data-Oriented Programming • https://amzn.to/3NFPbSV Yehonathan Sharvit • The Clojure Workshop • https://amzn.to/3NfFN77 https://twitter.com/GOTOcon https://www.linkedin.com/company/goto- https://www.instagram.com/goto_con https://www.facebook.com/GOTOConferences #Complexity #DataOriented #DataOrientedProgramming #Programming #SoftwareEngineering #YehonathanSharvit #Viebel #Immutability #Clojure CHANNEL MEMBERSHIP BONUS Join this channel to get early access to videos & other perks: https://www.youtube.com/channel/UCs_tLP3AiwYKwdUHpltJPuA/join Looking for a unique learning experience?
