Open Analysis Interfaces
SAP NetWeaver Business Intelligence provides an open architecture in many areas: You can extract data from various systems into a BW system and evaluate this data for your reporting using various front-end tools.
SAP Business Explorer, the front-end component of SAP Business Warehouse, provides flexible reporting and analysis tools to support strategic analysis and decision making in your organization.
The following interfaces are available to connect third-party front-end tools:
- OLE DB for OLAP (ODBO)
- OLAP BAPI (Business Application Programming Interface)
- XML for Analysis (XML/A)
- Easy Query
- OData
The following table provides an overview of the various interfaces:
| Criterion | OLE DB for OLAP (ODBO) | OLAP BAPI | XML for Analysis (XML/A) | Easy Query | OData |
|---|---|---|---|---|---|
| Technical Protocol | COM(Component Object Model) protocol |

The following overview illustrates the options for accessing BW data using interfaces.
Platform Dependency
The interface used depends on the platform: OLE DB for OLAP requires MS Windows, OLAP BAPI requires an SAP platform. XML for Analysis, Easy Query and OData are non-platform dependent.
