Open ODS View offers
• Metadata object as an abstraction layer for underlying source
object
• HANA virtual tables as supported source objects via SDA
• Querying on field level
• Supported for Teradata, Sybase ASE/IQ, Hadoop
• Optimized Query execution by pushing down to HANA
• Supported scenarios:
 Virtual Access
 Persistent Access *
o Switch from Virtual to Persistent *
o Based on Field based DSO including DTP and
Transformation
o Direct staging into DSO bypassing PSA
o No need to adjust existing queries
Easy assignment of semantics
• Underlying object (Table, DB View, DataSource) can be tagged
as Text, Master data or Facts
• Single fields of the object can be linked to already existing
Open ODS Views or InfoObjects
