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.
Each meta data object is given a name and the objects are arranged in the following object hierarchy: U-SQL metadata objects are name-scoped to their containers (e.g., views and tables are scoped to database schemas) which provide a single namespace for all object types within a container.
