- Simplification: Views can encapsulate complex SQL queries into a single, simple interface. This allows users to retrieve data without needing to understand the underlying query complexity. For example, instead of writing a complex join query every time, users can just query the view.
- Security: Views can restrict access to specific columns or rows in the underlying tables. This allows you to expose only the necessary data to users while keeping sensitive information hidden. For example, a view can include employee names and salaries but exclude sensitive data like social security numbers.
- Data Abstraction: Views provide an abstraction layer over the underlying data. Changes in the underlying tables do not necessarily affect how data is presented through the view, making it easier to adapt to changing business requirements.
- Consistency: Using views ensures that all users see a consistent representation of the data, even if the underlying data changes. This can be particularly useful in environments with multiple users needing to access data in similar formats.
