Problem Domain, Objects, and the DOM

Problem Domain:

Problem domain (or problem space) is an engineering term referring to all information that defines the problem and constrains the solution (the constraints being part of the problem). There are many common answers to this question:

• Learning a new technology
• Naming things
• Testing your code
• Debugging
• Fixing bugs
• Making software maintainable

Why problem domains are hard?

because you can’t really see what you are trying to build very clearly.

• The more and more I write code, the more I learn that understanding the problem is the most critical piece to the equation.

What can you do about it? If understanding the problem domain is the hardest part of programming and you want to make programming easier, you can do one of two things:

1. Make the problem domain easier
2. Get better at understanding the problem domain
