Metadata is  data about data. Two types of metadata exist: structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.hile the metadata application is manyfold covering a large variety of fields, there are specialised and well-accepted models to specify types of metadata. Bretheron & Singley (1994) distinguish between two distinct classes: structural/control metadata and guide metadata.
Metadata was traditionally in the card catalogs of libraries. As information has become increasingly digital, metadata is also used to describe digital data using metadata standards specific to a particular discipline. The business metadata tell you what data you have, where they come from, what they mean and what their relationship is to other data in the data warehouse. 2  Business metadata may also serve as a documentation for the DW/BI system. 3  Users who browse the data warehouse are primarily viewing the business metadata.
