View Dependencies

Description: View dependencies refer to the relationships between a view and the underlying tables or other views it depends on. In the context of databases, a view is a virtual representation of one or more tables, allowing users to query data in a simpler and more structured way. View dependencies are crucial for understanding how data is updated and maintained in a database, as any changes to the underlying tables can affect the view. This implies that views are not independent entities; their existence and functionality depend on the integrity and structure of the tables from which they derive. Additionally, view dependencies are essential for optimizing SQL queries, as they allow database management systems (DBMS) to determine how to execute queries more efficiently, minimizing response time and resource usage. In summary, view dependencies are a fundamental component of database architecture, facilitating data management and improving efficiency in information retrieval.
