I like to compare the process of creating a database solution to the construction of a house. If you start by hiring a contractor, you probably won’t get the house of your dreams. The first step is to hire an architect. You tell the architect you want five bedrooms, three bathrooms, a man cave and a swimming pool and he designs a house based on your specifications. The architect then shares the plans with you so you can validate his design. Maybe you decide to change a few things. The architect takes your input and create new plans. The process can go back and forth until the plans are satisfactory. The same process is necessary for proper database design so let me walk you through the steps to success.
