Key Differences
Data refers to raw facts and figures without context. It can be numbers, words, measurements, observations, or even just descriptions of things. Metadata, on the other hand, is data that provides information about other data. It's like a descriptor or a guide to understand data better.
In a database, data is the content in the records and fields - such as names, dates, and measurements. Metadata in a database might include the date a record was created, who created it, and file format details.
In research, data is the information collected during the experiment, like survey responses or experimental results. For the same research, metadata could include the methodology of how the data was collected, the instruments used, or the conditions under which data was collected.
In photography, the data is the image itself – the visual content captured in the photograph. In the same context, metadata includes the camera settings, the date the photo was taken, the file size, and the location if available.
In the context of a book, the data is the text – the story, information, or content written on the pages. For a book, metadata would be the publication date, author name, ISBN number, and genre.
