Data-Oriented Design: Software Engineering for Limited Resources and Short Schedules 

Projects tackled by the software development industry have grown in scope and complexity. The cost increases with the number of developers. Electricity bills for distributed projects have literally reached the point of optimization of paying dividends. In the past 10 years, a software development movement has taken root, a movement founded on game development. The limited resources and complexity of the software and hardware needed to deliver modern titles necessitated a different approach. Data-driven design is inspired by high-performance computing techniques, database design, and functional programming values. It provides a practical method of reducing complexity while improving the performance of your product and development teams. Understand goals, understand data, understand hardware, develop solutions. This book presents the foundations and principles for a deeper understanding of data-driven design. It provides guidance on the thought processes involved when considering data as a key detail of any project.

Description of the book

The thinking behind data-driven design is very similar to how you would think about relational databases. Relational database optimization is also possible through more efficient use of cache, even if in this case the CPU cache is not the cache of cached pages in memory. A good database designer would probably separate infrequently accessed data into a separate table rather than creating a multi-column table where only a few columns are used.

This book is a practical guide for serious game developers. It’s aimed at game developers working to make triple-A titles across multiple platforms, indie developers trying to get the most out of their chosen target hardware, in fact. Practically anyone develops advanced software in limited documentation.

This is a book on how to code. It’s a book written to educate game developers about a coding model that’s right for the future, unlike the coding style we’re all too familiar with. This is a book based on C++, the language of choice for game developers over the past decade, and provides practical advice on how to get around without throwing away code and years of accumulated experience. . This book explains how you can transform your growth.
