.... looking at using dynamic information to identify class collaborations (as in UML) such collaborations could be expressed in rules as invariants [Luc97] It is much easier to codify rules of programming style [Wuy98] or structural design patterns [KP96] than to codify architectural patterns [BMR 96] A model for architectural evolution and drift. Our case study suggests that although algorithms changed (as for constraint solving) and patterns used change (as for tools) the domain concepts and their roles remained quite stable. This suggests that the software be viewed as layers which ....

....to be passed on to novices. A distinction could be made between a pattern and a design pattern in that the latter is concerned with communicating components, and is independent of the implementation language. Other types of patterns could be language dependent, or of a more general nature (see [6]) The focus of this work is on design patterns, where the pattern is not too abstract as a notion to be formally speci ed. However, the approach could be generalized outside of design patterns where appropriate. The basic parts of a design pattern is the pattern name, the problem the pattern ....

This approach consists in defining a set of solutions that can be applied by designers when facing specific design problems.

This language can be seen as a partially ordered collection of related patterns that work together in the context of Hypermedia Interfaces [17] They help to capture the abstract interaction model between the user and the application. We have chosen the pattern style defined in [3] for the specification of the patterns. This style, largely based on the Alexandrian style [1] is best suited for abstract patterns with several possible ways of implementation, which are common characteristics of the hypermedia patterns.

In fact, even the architecture of the method (separation of logic, interface and data) can be viewed as an application of the Model View Controller [3] pattern. In this article we have proposed an interface enrichment process driven by patterns. The Pattern Catalog covers some of the most relevant characteristics that should be present in hypermedia applications, and gives a set of alternative implementations.

In the manufacturing example, the pipeline organisation between agents expresses an organisational pattern that is likely to re appear in many applications (indeed it is one that is already widely exploited as an architectural pattern in traditional software systems [4]) The same can also be said of the hierarchical pipeline structure. In both cases, if a catalogue of patterns was available, the designer could rely on it to help de ne the system structure.

A possible way to model these applications is by the use of the pipes and filters architectural design pattern [1]. Each filter accepts a data structure, processes the data, stores its results in the data structure, and passes it on the next filter. In a framework environment, we would implement these filters to be small but welldefined tasks in order to obtain a set of highly reusable filters. Making an ....

To date, research on patterns has been mainly focussed on recovering patterns from existing software to establish various pattern catalogues [2, 3, 4]. In the meantime, incorporating design patterns into current software process models has been comprehensively neglected, although more systematic ways of representing and using patterns are emerging recently, e.g. BACKDOOR method [5] from the University of Maryland. 2.1 GOF s Pattern Catalogue ....

In practical terms, a design pattern describes a con guration of a small set of objects whose cooperative behavior solves a software design problem. There are several useful books that describe design patterns [5, 8, 15]; our discussion follows that of Gamma et al. 8] most closely. We have found design patterns to be very helpful in solving some key design problems that arose during the construction of the SAMRAI software architecture. Some of these patterns are covered in detail in the following ve sections. ....

Therefore it is necessary to restrict oneself to one standard including the syntactic representation of the patterns like the standard proposed by Gamma et al. 2] or Buschmann et al. [3]. Patterns are flexible. Much of this flexibility follows from the separation of classes interfaces from their implementations. A software architecture based on communication between interfaces places no constraints on the implementation of the interface methods. Different classes may use ....

....familiar with the notation these ideas should (we hope ) be accessible within this space. We can rely on standard literature for explanation of the patterns, since excellent, reliable texts already exist. Proponents of OODPs have never claimed invention of the techniques described by patterns [2, 3, 9]. Most patterns have long been used by experienced programmers. The new idea is to name these wellknown structures and see them as independent, stand alone mini architectures that help us to build heterogeneous software. A good example for a welldesigned application of OODPs can be found in the ....

Observe that not all design patterns are influenced by their implementation language. Some patterns, such as Producer Consumer [BM95, Meu95] can be described independent of the programming language. The reason the Producer Consumer pattern is language independent is that the language constructs and mechanism it relies on (arrays or lists and functions) are basic enough that they can be found in any language. 9 Many design ....

Each pattern depends on the smaller patterns it contains, on the patterns it interacts with, and on the larger patterns it is contained within [1]. TOPS are higher level patterns in that they build upon other patterns [2, 6] Some of TOPS are domain specific, whereas others are more generic. PLOTS intends to show how these patterns collaborate with each other to achieve specific tasks for transport applications. It is through pattern ....
