So I have this peculiar solution that I want to develop using PHP and MySQL, and since I do not have ASP.NET running on this hosting package PHP and MySQL are the obvious options at this stage. The first step in creating a solution is to define it. You define a solution by describing what it is you want to achieve, and in so-doing determine all the variables and objects that might exist within your solution. Once you have described the solution you can start analysing it and start breaking it down into small usable pieces. I follow a practice whereby I develop small pieces of code at a time and test them as I go along (with your desired goal in mind).

I want to develop a breadcrumb navigation system for my website. That is the solution I want. How do I go about defining it? What is the purpose behind building a breadcrumb navigation system?
