The key building blocks of the Hadoop platform management layer is MapReduce programming which executes set of functions against a large amount of data in batch mode. The data source name (DSN) need not be the same as the filename for the database. Adding a source isn't enough to make data appear on the map because sources don't contain styling details like color or width. As the volume of data generated and stored by companies has started to explode, sophisticated but accessible systems and tools have been developed – such as Apache Hadoop DFS (distributed file system), which I cover in this article – or Google File System, to help with this task. This makes it possible to style the same source in different ways, like differentiating between types of roads in a highways layer.
