IBM Websphere Portal 8: Web Experience Factory and the Cloud

Overview of this book

IBM WebSphere® Portal is a cost- effective, scalable, and proven solution for the portal enterprise space. Given the depth and the breadth of WebSphere Portal and the challenges of developing a portal project, you need a book that covers all the nuances of the entire portal project lifecycle. This book accomplishes just that. In this book, we cover topics that range from portal assessment, governance, and architecture, to design and development. These topics are covered not only within these traditional areas, but also within the cloud environment context. Keeping both contexts in mind, several chapters are dedicated to portal and portlet testing, troubleshooting, performance monitoring, best practices, and tuning. The cloud option is also analyzed and discussed for hosting, developing, and publishing portal applications. We also cover Web Experience Factory (WEF) as the tool of choice for portlet development. We take you from the introduction to the development of advanced portlets in an intuitive and efficient manner. We cover not only common topics, such as builders, models, and user interface development, but also advanced topics, such as Dojo builders, Ajax techniques, and WEF performance. Within the WEF space, we cover other topics, which have never been covered before by any other competing book. You will learn how to develop multichannel applications, including web mobile applications and you will learn about the model types available for portlet development, including when and how to utilize them. We also present and discuss numerous aspects and facets of implementing a WEF project and what it takes to successfully deliver them. The richness and the profundity of the topics combined with an intuitive and well-structured presentation of the chapters will provide you with all the information you need to master your skills with the IBM WebSphere Portal project lifecycle and Web Experience Factory.

Preface

The Service Consumer and Service Provider patterns in WEF


The provider/consumer pattern is implemented through the usage of specialized models. As we saw in Chapter 7, Introduction to Web Experience Factory, models are comprised of builders. This being the case, by adding specific builders to a model, we can clearly define the tasks to be performed by these models. For instance, if we add UI-related builders such as Data Page, Link, Input Control, and so on to a model, it makes sense that this model will be responsible for handling the display and input of data. On the other hand, if we add builders such as Service Definition, Service Operation, Web Service Call, and other such builders, it makes sense that these models will be entirely responsible for data access and data manipulation.

The models responsible for data access and data manipulation play the role of Service Providers, and the ones responsible for the UI presentation are Service Consumers.
