WHY CDS VIEWS ARE USED
WHY CDS VIEWS ARE USED
A CDS view is a virtual table in the SAP Cloud Platform, CDS stands for Core Data Services, and the views serve as a way to expose data from various sources in a consistent manner.
The Benefits of Using CDS Views
There are several key benefits to using CDS views, including:
- Improved Data Access: CDS views provide a unified and centralized point of access to data from disparate sources, making it easier for developers and business users to query and report on data.
- Increased Data Security: CDS views can be used to restrict access to sensitive data by only exposing the data that is necessary for a particular user or role.
- Simplified Data Integration: CDS views can be used to integrate data from different sources into a single, cohesive view, making it easier to develop applications that use data from multiple sources.
- Enhanced Data Performance: CDS views can be used to optimize data performance by caching frequently accessed data and using indexing techniques to improve query performance.
How CDS Views Work
CDS views are created using the CDS view definition language, which is a declarative language that allows developers to define the structure and content of the view. CDS views can be based on existing tables, views, or other CDS views, and they can be used to perform a variety of data operations, including filtering, sorting, aggregation, and joining.
Types of CDS Views
There are two main types of CDS views:
- Entity CDS Views: Entity CDS views are used to represent data entities, such as customers, products, or orders. Entity CDS views can be used to perform CRUD (create, read, update, delete) operations on the underlying data.
- Calculation CDS Views: Calculation CDS views are used to perform calculations on data, such as calculating the total sales for a particular product or the average order size for a particular customer. Calculation CDS views can be used to create reports and dashboards.
Use Cases for CDS Views
CDS views can be used in a variety of scenarios, including:
- Reporting and Analytics: CDS views can be used to create reports and dashboards that provide insights into business data.
- Application Development: CDS views can be used to develop applications that use data from multiple sources.
- Data Integration: CDS views can be used to integrate data from different sources into a single, cohesive view.
- Data Security: CDS views can be used to restrict access to sensitive data by only exposing the data that is necessary for a particular user or role.
Conclusion
CDS views are a powerful tool that can be used to improve data access, security, integration, and performance. By using CDS views, developers and business users can gain a more comprehensive and accurate view of their data, which can lead to better decision-making and improved business outcomes.
