Oracle BI Publisher Interview Questions - Part I
What is BI Publisher?
BI Publisher is a reporting tool for generating the reports. More than tool it is an engine that can be integrated with systems supporting the business.
What is XML Publisher?
Oracle XML Publisher is a template-based publishing solution delivered with the Oracle E-Business Suite. It provides a new approach to report design and publishing by integrating familiar desktop word processing tools with existing E-Business Suite data reporting. At runtime, XML Publisher merges the custom templates with the concurrent request data extracts to generate output in PDF, HTML, RTF, EXCEL (HTML), or even TEXT for use with EFT and EDI transmissions.
What is the difference between XML publisher and BI Publisher?
XML Pub operates entirely within EBS and can only be used within EBS. BIP can be installed as a standalone version running off of several OC4J compliant engines, such as Application Server and Tomcat. BIP can be pointed anywhere, so you could do reports out of an OLTP or warehouse database, MSSQL and even within EBS. Licensing is already included in EBS, and the standalone costs whatever plus maintenance.
