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.
Examples of relational-database metadata include: 1  Tables of all tables in a database, their names, sizes and number of rows in each table. 2  Tables of columns in each database, what tables they are used in, and the type of data stored in each column.
