What is the difference between Explorer, formerly called Polestar, and the new accelerated version for BW?
SAP BusinessObjects Explorer is the new name for the intuitive search and exploration capabilities from the portfolio of SAP BusinessObjects BI solutions. The product was formerly called SAP BusinessObjects Polestar. It was recently renamed into SAP BusinessObjects Explorer to clearly describe the value it provides. Explorer is deployed with SAP BusinessObjects Enterprise and it can access any data via universes. It is important to note that although Explorer can access BW cubes via universes, SAP recommend customers to deploy search and exploration based on the accelerated version (see below) to benefit from optimal performance and scalability.
SAP BusinessObjects Explorer, accelerated version for SAP NetWeaver BW is a bundled offering that combines Explorer capabilities, as described above, with the high-performing, scalable in-memory analytics and acceleration capabilities from SAP NetWeaver BW Accelerator. The accelerated version provides direct access to BW cube data that has been indexed in BW Accelerator. It does not require universes to do so.
The accelerated version is available as a blade server appliance preloaded with all SAP NetWeaver BW Accelerator and SAP BusinessObjects software required. Series of blade servers certified for the accelerated version are available from the same hardware partners as for BW Accelerator (i.e., Fujitsu, HP, IBM, and SUN) and SAP customers are free to choose any of those. SAP recommends the blade server appliance approach for optimal performance and scalability.
Explorer and the accelerated version can be deployed together in the same SAP BusinessObjects Enterprise environment already in place and/or aimed at supporting an enterprise BI strategy. In such an enterprise-wide deployment all business users can search and explore all data sources in the organization, the full benefit of accelerated exploration will only apply when exploring the BW data sources, though.
