Description: The ‘View Schema’ refers to the structure of a view in a database, including its columns and data types. A view is a virtual representation of one or more tables in a database, allowing users to query data in a simplified and organized manner. Unlike a physical table, a view does not store data itself; instead, it relies on queries executed against underlying tables. This allows views to act as an abstraction layer, facilitating access to complex data and improving security by restricting access to certain columns or rows. Views can include calculations, joins, and filters, making them powerful tools for optimizing SQL queries and presenting data. Additionally, the schema of a view can be modified without affecting the original tables, providing flexibility in data management. In summary, the ‘View Schema’ is fundamental for organizing and manipulating data in database systems, enabling developers and administrators to create more efficient and secure solutions.
