According to Mircea and Andreescu (2009), a BI system monitors operational transactions (1), integrates BI data (2) for decision analysis (3) across multiple end user platforms (4), as conceptualized in Figure 1. Furthermore, modern BI systems integrate data by utilizing Extensible Markup Language (XML), a tagging methodology which eliminates barriers inherent in proprietary technology products (Mircea & Andreesci, 2009).

At the heart of a BI system is the BI access method (BAM) which employs Service Oriented Architecture (SOA) as a cross-platform application software communication standard to read, interpret and write BI data using XML (Mircea & Andreesci, 2009). Business Process Software (BPM) is used to apply decision rules for competitive prioritization and risk analysis, including encompassing the requirements needed for compliance with the Reserve Bank of India (RBI) requirements (Jafartarokha & Teymournejada, 2012). The BI data is output to email, workflow systems, and online executive 'dashboard' reports, using XML, as illustrated in Figure 1.
In a typical BI system implementation, on one side, there is a vendor or a system integrator (Zavodny, 2013). On the other side there is a user. Both the vendor and user complete a requirement analysis first to understand the business requirement at the top management level. Then they try to determine how the user can translate these requirements into a software and database design so that BI engine can answer all the questions that a future user might ask (Nandi, 2012).
