This paper outlines the preliminary and detailed design process for an enterprise-level business information system. It evaluates trade-offs among cost, schedule, and performance across three major platforms — Oracle, Microsoft, and PeopleSoft — examining the pros and cons of each in terms of usability, security, scalability, and organizational fit. After analyzing these options, the paper recommends Oracle Grid Computing as the final design choice, citing its modular cost structure, server redundancy, and capacity to function as a unified organizational system. The paper also addresses standards for interdepartmental data sharing, security protocols, and human-computer interface considerations relevant to implementation.
This section specifies trade-offs among cost, schedule, and performance to be used in the final design choice for hardware, software, and human interface. It also includes a discussion of the rationale for these design choices and any known impact on achieving the confirmed system requirements.
Three major platforms were evaluated: Oracle, Microsoft, and PeopleSoft. Each was assessed for its suitability as the foundation of an enterprise-level business information system.
Oracle's grid system allows the coordinated use of servers and storage across an organization. Its "one computer" approach encourages greater unity in management structure, facilitates data sharing, and eliminates the problem of separate interfaces. Oracle's Linux technology is also an industry leader in website design, and its troubleshooting support would be critical in creating a new interactive website.
Oracle's grid architecture can turn 64 small servers into a single giant mainframe. It is fast, cost-effective, and highly reliable — when one server goes down, the overall system continues to run (Oracle, 2004).
The system could be intimidating for non-technical staff during training and in day-to-day use, which may require additional onboarding resources.
Microsoft is user-friendly and an industry leader. Because Windows is used by many other systems, adopting it could help expand the customer and vendor base through greater compatibility.
Microsoft systems are a frequent target for viruses. Creating a highly integrated database on a Microsoft platform could pose significant security risks, even with password protection in place for staff.
