Fusion is supposed to combine the best attributes of Oracle's other ERP (enterprise resource planning) lines, such as E-Business Suite and PeopleSoft, along with pervasive BI (business intelligence) functionality. "It's important for them to say 'we're open for business with Fusion' and show some customer adoption" at OpenWorld this year, said Forrester Research analyst Paul Hamerman. Oracle Senior Vice President Steve Miranda is expected to do something along those lines during a keynote address and customer panel discussion on Wednesday. There are other gaps for Oracle to fill in the Fusion Applications story, namely just how the reported SaaS (software-as-a-service) option will work and be priced. So far, pricing has only been released for the on-premises versions. Oracle also could make clearer what current E-Business Suite, JD Edwards and PeopleSoft customers are entitled to under their maintenance payments in terms of an upgrade to similar Fusion modules.
