Enterprise Application Integration (EAI) 101 HOW ORACLE RE-ARCHITECTS ITS GLOBAL INFRASTRUCTURE INTO A CENTRALIZED E-BUSINESS ARCHITECTURE Oracle Corporation, like other large corporations had built a huge, distributed, worldwide culture based upon a client/server-computing infrastructure. For example, the company had 60 disparate financial systems in 60 different countries and 120 e-mail databases globally. Oracle was spending $600 million annually on global IT operating costs and the support of 1500 IT personnel to maintain them. The profit margins of the company were only 20% rather than 60% that successful software companies usually experience. Through a closer scrutiny of their business processes, the management realized that the 60 independent profit centers of the company created expensive redundancy uncontrolled spending, lower productivity and huge maintenance bills. The company was spending uncontrollably, adding more databases, applications and client/server infrastructure to support the phenomenal growth, while exponentially increasing the complexity. Realizing this, the company began a rather tough, but rewarding journey of re-architecting its systems into a centralized e-business model that dramatically reduced maintenance on the desktops, inherently eliminated unnecessary servers and databases and greatly reduced IT and maintenance cost. For example, Oracle consolidated 97 e-mail servers and 120 databases into 4 servers running 4 databases and implemented a 'direct standards' model that allows it to maintain and update centralized applications worldwide from a single, centralized data center. Through this re-architecture of its systems, Oracle has reduced its operating budgets from $600 million to $440 million annually.

A word of caution Unfortunately, most IT shortcomings exist even today. One only needs to substitute the term 'Web-based' for 'client-server' to see this. The
102 B2B Integration — A Practical Guide to Collaborative E-commerce situation has never been more apparent than with the swift rise, and even swifter fall, of the Internet dot-coms. Both old and new economy companies rushed into the 'sexiest' Internet technologies without any regard for ROI, revenue or shareholder value. Today, with one eye on the enormous implementation costs and another eye on the failure of the dot-coms, many companies have taken a more cautious approach. As the saying goes: "the more things change, the more they stay the same." The benefits of EAI are great, but so are the pitfalls, if one does not approach it in a systematic, cost-effective manner. 4.5. Types of EAI EAI solutions can take on many forms and exist at many levels. The appropriate level of EAI can be dependent on many factors including company size, company industry, integration/project complexity and budget. There are three types of middleware solutions to EAI: • User Interface Integration; • Data Integration; • Function or Method Integration; and • Business Method Integration. A brief overview of each of these levels of EAI include: 4.5.1. User interface integration (Refacing) Refacing is the process of replacing the terminal screens of legacy systems and the graphical interfaces of PCs with one standardized interface, typically browser-based. Generally, the functionality of terminal screens applications can be mapped on a one-to-one basis with a browser-based graphical user interface. The new presentation layer is integrated with the existing business logic of the legacy systems. Enterprise business portals may also be considered a sophisticated refacing solution. A business portal consolidates the presentation of multiple applications into one customizable browser-based interface. A
