Describe the merits of metadata
What will be an ideal response?
A database is self-describing in that it contains, within itself, a description of its contents. This is because it contains not only data, but also data about the data in the database. This data is known as metadata. It is the presence of metadata that makes databases much more useful than spreadsheets or data in other lists. Because of metadata, no one needs to guess, remember, or even record what is in a database. To find out what a database contains, we just look at the metadata inside the database.
