But there has to be a regular collection of that data in a consistent way, because if data is not consistent, your conclusions that you draw from that data are fraught with error and mistakes. Construction Engineering and Management Certificate, Machine Learning for Analytics Certificate, Innovation Management & Entrepreneurship Certificate, Sustainabaility and Development Certificate, Spatial Data Analysis and Visualization Certificate, Master's of Innovation & Entrepreneurship. Thanks for watching this video. The data storage at that time with this massive machine was a whopping seven megabytes, which we, in our comfortable, modern world would giggle because seven megabytes isn't even a song download today, but at that time that was a tremendous advance.
