Document Summary
Unit 1: section 1: discuss the difference between data, information, and metadata, data is the stored representations of objects and events that have meaning and importance in the user"s environment. Limited data sharing - users have little opportunity to share data outside their own applications. Identify three other columns for these data (i. e. , three other metadata characteristics for the listed attributes) and complete the entries of the table in table 1-1 for these three additional columns. Problem exercise 6: a driver"s license bureau maintains a database of licensed drivers. State whether each of the following represents data or metadata. If it represents data, state whether it is structured or unstructured data. If it represents metadata, state whether it is a fact describing a property of data or a fact describing the context of data: driver"s name, address, and birth date. Essential individual items of database, these are structured data.
