Sprint previously used a one-off approach to connect its departments, customers, and partners to its mainframe systems. Four years ago, the telecom provider began experimenting with a more modular approach, then reusable components in a service-oriented architecture. The company has found that its SOA keeps the company from reinventing the wheel when integrating a new project or initiative.

In "Part 1: Thinking Mobile," we described how interfaces to network services could be defined and implemented at a level of abstraction, regardless of the mobile network or underlying network protocol layers. This means that we can "talk" to network services directly from any cellular phone that has a standard Java implementation (Java ME) without any concern over whether we are using 2G, 2.5G, or 3G mobile networks, or whether the underlying network protocol is iMode, WAP, or HTTP. In this article, we are going to extend the facilities of our architecture by adding the ability for devices to become involved in atomic transactions. Transactions are vital in ensuring that all of the relevant resources that a system provides are coordinated and managed so that the overall state of the system remains consistent.

This article is written for readers looking at and considering efficient, flexible, and standards-based approaches to implementing real-world service-oriented architectures, or SOAs. With the proliferation of Web services and, hence, SOAs as viable approaches to developing and enhancing software architectures, it is imperative to acknowledge that the amount of SOA data will also continue to grow. Furthermore, as the Web services standards stack broadens in functionality, the number of SOA artifacts required to support these new standards grows by the day. We must recognize the obvious need to store, manage, query, manipulate, and transform SOA data. Also, requesting applications frequently access SOA data. A case can thus be made for a mid-tier cache that exposes technology-independent, reusable, and functionality-rich services, hence, improving SOA scalability and performance. Additionally, as enterprises engage in collaborations with trading partners, interaction with complex schemas becomes a challenge. Thus, more than just a simple XML persistence mechanism is needed. A native XML data management server lends itself seamlessly to such complex demands for SOA data management.

In recent times, Service Oriented Architectures (SOA) have become synonymous with web services, in which large enterprise systems communicate business-critical information. However, in this series of articles, we look at SOA as a wider design principle that can be applied to any distributed object-based system--casting the net wider to include devices that sit at the edge of the network, both fixed and mobile. In this first article, we describe how we have taken SOA onto mobile devices and show how to implement a simple messaging application using mobile SOA design principles and point to some of the security implications and how to handle them.

Use multiple Service-Oriented Architectures (SOA) to close enterprise system gaps. Judith M. Myerson shows you four scenarios that combine Web services into a composite application in a single SOA, multiple SOAs, a single SOA with multiple EAI applications, and multiple SOAs with EAI applications. While still considering various trade-offs, determining the maximum number of SOAs a system can carry helps you avoid SOA overloads.

The use of heterogeneous technologies and applications in corporations is a reality. At a time when resources are scarce, IT shops cannot just throw away their existing applications; rather, they must leverage their existing investments. service-oriented architecture (SOA) is popular because it lets you reuse applications and it promises interoperability between heterogeneous applications and technologies. In this article, I will introduce SOA from a Java developer perspective and examine the technologies available in the Java space to build service-oriented applications.
