Tell, Don't Ask - Design Defined | Bresslergroup

Описание: There are an infinite number of ways to write the software for an embedded system. How do you decide which way is the right way? Your number one priority should always be to write code that meets the system requirements. But how the code is written can have an immense impact on modularity, maintainability, and testability.

"Tell, Don't Ask," or "TDA" has been popular among object-oriented programmers for years. Essentially, it says objects should be responsible for their own data, and those objects should be the ones to make decisions based on that data, not the application at large. The principle lends itself well to IoT products that combine real-time data collection and an asynchronous networking module.

Learn more about TDA in this 'Design Defined' video with Senior Embedded Software Engineer, Ian Adam.
