WHAT IS ORACLE BUSINESS INTELLIGENCE (BI) PUBLISHER?

• Oracle Business Intelligence Applications are complete, prebuilt BI solutions that deliver intuitive, role-based intelligence throughout an organization. 
• BI Publisher can be used as an alternative reporting solution to OTBI. Some of the data sources available are SQL Query, XML, HCM Extract, and View Object (brought in through web service, ADPI, etc.). 
•  BI Publisher works as an enterprise reporting solution for authoring, managing, and delivering reports from multiple data sources in multiple formats through multiple channels (E.g., checks, invoices, remittance, etc.). Utilize BI Publisher for writing your own SQL query, formatting reports, joining historical data with real-time information, and report bursting. Typical end users include Technical Human Resource Information System (HRIS) and IT Developers.

WHAT IS ORACLE TRANSACTIONAL BUSINESS INTELLIGENCE (OTBI)?

• OTBI provides a flexible and easy to use analysis tool that helps to gain real-time insight into transactional data.
• OTBI is aimed at business users and especially shines when the report creator is someone who does not know SQL and/or the underlying table structures. 
• OTBI’s core functionality allows users to simply drag and drop selected data from subject areas and use different graphical views. Data can be filtered, drill-down can be enabled, and action links can be created. Reports or dashboards can be scheduled for delivery and reports can be exported to Excel, Word, and other formats. A reporting wizard (BI Composer) is available to guide casual business users through a few simple steps to run, edit or create OTBI reports and queries. 
• Typical end users include Financial Analysts, Compensation Analysts, Benefit Analysts, and Human Resources Analysts.
