The Oracle Enterprise Architecture Framework
The Oracle Enterprise Architecture Framework helps Oracle to collaboratively work with customers in developing strategic roadmaps and architecture solutions that enable business and IT alignment. Oracle emphasizes a "Just enough" and "Just in time" practical approach to Enterprise Architecture, which may be used standalone or as a complement a customer's selected EA methodology. By focusing on business results and leveraging Oracle's unique EA assets and reference architectures, the Oracle Enterprise Architecture Framework can be employed to efficiently create architecture roadmaps for implementing business-driven enterprise solutions.

IT organizations that are seeking to drive down operating costs while delivering business projects on time and on budget find they must manage their application portfolios to provide an optimal foundation for execution. Application Portfolio Management (APM) captures and organizes information about the application portfolio so that business and IT execs can make prudent decisions around investing/replacing/ retiring applications. When enterprise architecture is integrated with application portfolio management, the alignment with architecture road maps and business views improves the overall results for business and IT. This paper summarizes the results of a custom research project conducted for Forrester's Enterprise Architecture Council on best practices for integrating enterprise architecture with APM.

Service-Oriented Architecture (SOA) has been around a long time. But before adopting SOA corporate-wide, organizations justifiably want to be able to see the benefits of it. Many organizations and consulting firms have taken a variety of approaches when trying to demonstrate the value of SOA. In this paper learn how one can leverage SOA to systematically develop an organization's enterprise architecture and realize the benefits of SOA.

In this paper, learn about some fundamental challenges that IT teams face when working with enterprise architects, and find out how to apply enterprise architecture standards to application development and cooperate in project delivery to reach a desired outcome. The role of Enterprise Architecture (EA) is changing. Adoption of Service-Oriented Architecture (SOA), Web 2.0, and other technologies is changing the way software systems are built. Traditional EA concepts were developed before SOA and Web 2.0. They are more suited to large application development projects, rather than the agile, services-based development.

Enterprise Open Architecture (OA) is a pattern of nonfunctional requirements that can help one create and maintain more open and flexible complex systems, and systems of systems. Organizations with large, complex systems are looking to OA to help manage complexity, increase flexibility, and reduce their costs. Satisfying the OA nonfunctional requirements (open standards, modularity, interoperability, extensibility, reusability, composability, and maintainability) in system design and implementation is essential to OA at the enterprise level. In this paper, learn about the enterprise business drivers behind OA, and the OA nonfunctional requirements. Associated architectural principles that address the requirements are also covered.

In this paper, design a set of services that defines an enterprise architecture blueprint to support business goals. Discover how hierarchical decomposition can help the user align services to support both current and future business functions. One also learns how to define interfaces for services as part of the Service-Oriented Architecture (SOA) decomposition and use a semantic data model for maximum interoperability.

After successfully building the new IT enterprise architecture, it's time to test it. Testing proves that the hard work the user and his team has put in really works. By stressing the new architecture, one will know where its weaknesses are and how well it will serve the enterprise. Now that one has built the enterprise architecture, one must test it. New technology, especially technology that's on the bleeding edge, will have some kinks to work out. Testing the Information Technology (IT) architecture is all-inclusive. Testing should include the hardware, applications, and the people responsible for those systems. Testing is a great way to break things and get paid for it. While no one ever wants their IT systems to break, odds are that they will.

Building great IT architecture takes time and planning. By assessing what is already in place, then visualizing what it should be, one can make great enterprise architecture a reality. To achieve the dream architecture, learn what to build, how to build it, and what to build it on in this paper. In this paper, learn what to build and how to build it. Let's assume that as the IT architect, one is not lucky enough to work in a clean environment - a place in which one gets to build the enterprise IT architecture from scratch. Like most IT architects, one will be building around a current environment in which good intentions stopped short of being perfect.

When developing an enterprise architecture, multiple applications will require modeling support. To efficiently handle this task, one needs to establish a framework to contain and organize all modeling artifacts to enable collaborative work among dependent groups. This provides two main benefits: uniformity of model organization for maintenance and management of intermodel dependencies. In this paper, explore the structural and management issues around the creation of a robust enterprise architecture repository, which can allow the user to fully exploit the organization's existing assets.

This three-part series of papers covers the similarities and differences between SOA and EA, and shows how to address the potential problems that result from their overlap based on a real customer engagement. In this engagement, IBM provides a broad range of business transformation and IT outsourcing services and manages all of the client's IT operations - mainframe, midrange, desktop, help desk, voice and data network, application development, and maintenance. The engagement required both SOA and EA to be developed concurrently.
