For my final year project, i would like to build decision support system that give suggestion to customer to build their house based on type of house and price. So, customer will select type of house that they like and also the budge money that they have. Then, the system will display the type of house that they want within their budget. This system will be similar as medical decision support system. My question is how to build decision support system using php? Can anyone give tutorial or example of code for making dss? What i need to know to build this system?
