Building Enterprise Systems with ODP: An Introduction to by Peter F. Linington

By Peter F. Linington

The Reference version of Open allotted Processing (RM-ODP) is a global normal that gives a pretty good foundation for describing and development largely dispensed platforms and purposes in a scientific method. It stresses the necessity to construct those platforms with evolution in brain through picking out the troubles of significant stakeholders after which expressing the layout as a chain of associated viewpoints.

Although RM-ODP has been a regular for greater than ten years, many practitioners are nonetheless ignorant of it. Building company structures with ODP: An creation to Open allotted Processing deals a gradual pathway to the fundamental principles that represent ODP and indicates how those principles will be utilized whilst designing and construction tough platforms. It presents an obtainable creation to the layout ideas for software program engineers and company architects. The publication additionally explains the advantages of utilizing viewpoints to provide less complicated and extra versatile designs and the way ODP may be utilized to provider engineering, open company, and cloud computing.

The authors comprise directions for utilizing the Unified Modeling Language™ (UML) notation and for structuring and writing approach standards. They elucidate how this matches into the model-driven engineering device chain through methods, reminiscent of Model-Driven Architecture® (MDA). additionally they reveal the facility of RM-ODP for the layout and association of advanced allotted IT platforms in e-government, e-health, and effort and transportation industries.

All suggestions and ideas within the publication are illustrated via a unmarried operating instance that describes the IT aid wanted by way of a medium-sized corporation because it grows and develops. entire UML versions and extra can be found at http://theodpbook.lcc.uma.es/

Sample text

Since ODP system designs are typically large collaborative efforts, it is likely that the actual process will be iterative, filling in detail in different parts of the specification as ideas evolve and requirements are better understood. However, the sequence in which this is done will depend on circumstances. In a green field, design may follow a classical top-down, waterfall-style pattern. In a legacy migration exercise, it will start by capturing existing constraints. In an agile or rapid prototyping environment, design will stress modularization and fine-grained iteration.

The specification of an interaction concentrates on the objects participating in it. However, in some circumstances, we may want to focus on exactly where the interaction takes place and how it might be observed. This is done by introducing the concept of an interaction point, which is concerned with where, in time and space, the interaction happens. We shall see later, in chapter 8, how this concept leads to the more specific ideas of reference point and conformance point when we are concerned with ensuring that some interactions are observable during testing.
