What is Data Scheme? Data Scheme is a diagrammatic representation that illustrates data structures and data relationships to each other in the relational database within the data warehouse.
The data structures have their names defined with their data types.
Data Schemes are handy guides for database and data warehouse implementation.
The Data Scheme may or may not represent the real lay out of the database but just a structural representation of the physical database.
Data Schemes are useful in troubleshooting databases.
