What is the main benefit of using Virtual Data Models in SAP HANA?

The main benefit of using Virtual Data Models (VDMs) in SAP HANA is enhanced reporting agility. VDMs allow users to create views over existing data in real-time without creating physical data copies. This leads to quicker access to insights and reports since users can work with the most up-to-date data directly from the source systems. The agility comes from the flexibility that VDMs offer in terms of combining data from multiple sources and providing a simplified view for reporting and analysis.

Additionally, by using VDMs, organizations can adapt their reporting to changing business requirements without the need for extensive data preparation processes, which can be time-consuming. This adaptability enhances decision-making capabilities as users can generate and modify reports on the fly, respond to new queries quickly, and align insights with current business scenarios more effectively.
