< DATA >

~ typically the results of measurements and can be the basis of graphs, images, 
or observations of a set of variables.

~Data can exist in a variety of forms -- as numbers or text on pieces of paper, as bits 
and bytes stored in electronic memory, or as facts stored in a person's mind.

~ In database management systems, data files are the files that store the database information, whereas other files, such as index files and data dictionaries, store administrative information, known as metadata.
