If the data are processed consequently as it is usually made when data amount is large, then the virtual memory pages will be loaded and stored also consequently. If it is not so, then I/O model faces same problem. Of course, for big, complex, concurrently accessed data structures there should be an interface to access them. Ada is very good for it.
