A Functional Pattern System for Object-Oriented Design
Content description, abstract and table of contents, by Thomas Kühne.
div table { font-family: Arial, Helvetica, sans-serif; font-size: small; } --> FPS Functional Pattern System FPS - Functional Pattern System A Functional Pattern System for Object-Oriented Design , Hamburg, Germany, 1999
Design patterns inspired by functional programming concepts can advance object-oriented design
This thesis promotes the idea that concepts from the world of functional programming can be captured with design pattern descriptions
The functional patterns are evaluated for their impact on language design and a new approach to a dual-paradigm language is presented
Content Description This book integrates the vital areas of object-orientation, functional programming, design patterns, and language design
The most important concepts from functional programming are captured with six design patterns
Pattern Description Function Object Black-box behavior parameterisation Lazy Object Evaluation-by-need semantics Value Object Immutable values Void Value Abandoning null references Transfold Combining internal & external iteration Translator Homomorphic mapping with multi-dispatch functions These patterns can be used with any object-oriented language to advance software design

Object-Oriented Analysis & Design: Methods Intro 'What is a methodology; and who needs one anyway? Is a methodology a notation; or a process; or neither; or both? Many practitioners mislead themselves into believing they are using a methodology, when all they are using is its notation
On the other hand, a notation is an important component of a methodology and cannot be selected arbitrarily, as we and others have pointed out - it needs to be designed for optimal useability

Object-Oriented Analysis & Design: Tools Intro 'CASE tools offer many benefits for developers building large-scale systems
As spiraling user requirements continue to drive system complexity to new levels, the CASE tools enable us to abstract away from the entanglement of source code, to a level where architecture and design become more apparent and easier to understand and modify
As developers interact with portions of a system designed by their colleagues, they must quickly seek a subset of classes and methods and assimilate an understanding of how to interface with them
In a similar sense, management must be able, in a timely fashion and from a high level, to look at a representation of a design and understand what's going on

Object Oriented Analysis and Design Using UML A white paper that takes a look at the Unified Modeling Language notation, by
Mark Collins-Cope.
Object Oriented Analysis and Design Using UML 1
Introduction You’re proficient in C++, Java or another OO language, you’re designing class hierarchies, using inheritance, and manipulating complex pointer relationships to store the necessary links between your classes
Perhaps you’re feeling the need for a more formal notation to express your designs - using something that is language independent, and that enables you to consider the important aspects of design leaving the detail for later
Alternatively, perhaps you’re a Project Manager, looking to formalise the OO design process a little to make sure you’re getting the most from your move to C++/Java or a similar language
In this paper, I take a look at the UML (Unified Modelling Language) notation for Object Oriented Analysis and Design - the emerging standard designed by Booch, Rumbaugh and Jacobson, each of whom previously had their own notations published independently
This can be shown more clearly by the following instance diagram (instance diagrams are used to assist in understanding and clarifying Object Models - they also give quite a hint as to how relationships can be implemented in C++!): Figure 3 - Instance Diagram Showing Branch and Account objects By now, you may be beginning to see how Object Models can assist the analysis/design process
Design of Object-Oriented Real-time Systems
Goal: develop method to design real-time systems that: is practical for large
scale, complex systems; includes support of OO techniques to achieve reuse in ...
Design of Object-Oriented Real-time Systems Design of Object-Oriented Real-time Systems In this directory you will find several papers that have been written as part of the DOORS (Design of Object-Oriented Real-time Systems) project at, Ottawa Canada
You will also find several papers from a related project called Formal Methods in Design that builds upon some of the ideas from DOORS
The general objective of DOORS is to develop a method for the design of real-time (RT) systems that: is practical for systems of large scale and complexity; includes support of object-oriented (OO) techniques for achieving reuseability in implementations; helps with visualizing and testing design concepts during the early stages when the big decisions are being made
This output will be useful to designers of real-time systems to help them do their job better, and to designers of future tools (including future versions of ObjecTime) to help them identify the capabilities required
Important tasks are: development of a new design method that focuses on a concept we call timethreads, the method is called Timethread-Driven design; visualization techniques for OO frameworks and design guidelines for frameworks; research into integrating the ideas of our design method into CASE tools; and new visualization techniques for displaying the structure and behaviour of a large system in a limited screen area
The Karlsruhe Library of Algorithms and Data Structures (Karla)
An object-oriented library of data structures and algorithms designed for reuse
for Sather-K.
The Karlsruhe Library of Algorithms and Data Structures (Karla) The Kar lsruhe L ibrary of A lgorithms and Data Structures ( Karla ) is an object-oriented library of data structures and algorithms designed for reuse
The main goal of this project is to design a reliable object-oriented library of algorithms and data structures
Further design goals include flexibility and efficiency
In order to achieve the design goals, we constructed Karla by consequently using the mechanisms of refinement, specialization and genericity of classes
In the implementation phase, we identified and consequently employed several design patterns
In addition to the library itself, we have designed a comprehensive information and configuration tool that allows for navigation in the library structure and the definition of projects
Availability The design of Karla is independent of a specific language
Overview There are several papers outlining the design rationale, documentation rules etc

Upcoming: A two day session, Eiffel and Design by Contract by Dr
The seminar brochure in PDF format is available at: Overview The notion of Design by Contract is central in the systematic approach to object-oriented software construction, as embodied in the Eiffel method
This article introduces such a method, known as Design by Contract
Under the Design by Contract theory, a software system is viewed as a set of communicating components whose interaction is based on precisely defined specifications of the mutual obligations -- contracts
The benefits of Design by Contract include the following: A better understanding of the object-oriented method and, more generally, of software construction
The Design by Contract theory, then, suggests associating a specification with every software element
This has the advantage that the specification language is embedded in the design and programming language (here Eiffel), whereas formal specification languages are typically non-executable or, if they are executable, can only be used for prototypes
Christopher Alexander: An Introduction for Object-Oriented Designers
A review of Christopher Alexander's major texts, interspersed with remarks about
the architect's methodological and pragmatic concerns and software design.
Christopher Alexander: An Introduction for Object-Oriented Designers SUNY Oswego / NY CASE Center Last Content Change: 11 December 1993 (Reformatted 2 January 1997) Contents Introduction Software developers lament ``If only software engineering could be more like X ...'' , where X is any design-intensive profession with a longer and apparently more successful history than software
In part because it is considered as much artistry as engineering, writings about architecture have most extensively explored and argued out the basic underpinnings of design
Even within this context, the ideas of the architect Christopher Alexander stand out as penetrating, and bear compelling implications for software design
Alexander is increasingly well-known in object-oriented (OO) design circles for his influential work on ``patterns''
This paper considers patterns within a broader review of Alexander's prolific writings on design
The format is mainly topical, roughly in historical order, interspersed and concluded with remarks about connections to software design
Alexander's central premise, driving over thirty years of thoughts, actions, and writings, is that there is something fundamentally wrong with twentieth century architectural design methods and practices
Introducing Demeter and its Laws
Adaptive Programming - specifying the connections between objects as loosely as
possible. Makes programs more flexible, more resilient to change, ...
It is a design-style rule for object-oriented programs
There are also several design patterns for adaptive programming
The Demeter tools for Java make use of ' Adaptive Visitors ' objects which are AP analogs of the 'Visitor' pattern from the now famous Design Patterns book by the 'gang of four' (or GoF): Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides
They present a bunch of design/programming guidelines and rules for writing classes and class libraries to make them into reusable class frameworks (usable by client subclasses as well as 'normal' clients)
Pattern tools
Tool support for object-oriented (design) patterns.
Tool support for object-oriented (design) patterns This page gives some information about the patterns tools we have worked on at the
Background I believe that patterns make it possible to talk about (and perhaps also think about) designs on a higher level of abstraction
In early design it is enough to know that you're using a pattern at some point
design patterns vs
language-idioms) it should be possible to combine and glue together patterns into a design that can be mapped to different programming languages
They suggest a general solution and give you freedom as to how to put them in the design and how to implement them
the design level: where you see the structure of your design in terms of classes, methods, association and inheritance relationships, etc
The fragment model/database store the program being developed as a graph of design elements such as classes, method definitions, inheritance relations, etc.
The suite of design elements can be extended easily through the introduction of new fragment types
Design patterns are also design elements and represented as fragments
DBMS - June 1996 - Object-Oriented Analysis and Design
A June 1996 article by Michael Gora comparing several major methodologies.
Object-Oriented Analysis and Design By Michael Gora DBMS , May 1996 The good, the bad, and the ugly of OOAD methodologies, and various approaches to using them
This implies that an OO analysis and design (OOAD) methodology should be an effective guide to applying these tools to business problems
My most common approach to OO methodology involves fairly strict adherence to OO design and construction guidelines as appropriate to a particular language, but a very loose and flexible approach to OO analysis
The architecture of the EIS/DSS system we designed was based on LISP-based OO and artificial intelligence (AI) systems that Brown created for NASA and the Department of Defense while he was at Mitre
For the last three years, however, almost all my technical work (that is, some of the analysis and all of the design and development) has been object oriented
According to Donald Firesmith in his book Dictionary of Object Technology (SIGS Books, 1995), analysis is 'the development activity consisting of the discovery, modeling, specification and evaluation of requirements, ' while OO analysis is 'the discovery, analysis and specification of requirements in terms of objects with identity that encapsulate properties and operations, message passing, classes, inheritance, polymorphism and dynamic binding.' Firesmith also states that OO design is 'the design of an application in terms of objects, classes, clusters, frameworks and their interactions.' In comparing the definition of traditional analysis with that of OOAD, the only aspect that is really new is thinking of the world or the problem in terms of objects and object classes
Object Oriented Programming in C
Paul Field's fine, clear paper, published in C Vu 4:1 (November 1991), on how to
use an object-like discipline with a procedural language.
It seems to be a common myth that you need an object-oriented language to implement an object-oriented design and, although languages such as C++ and Smalltalk provide many features that encourage this style of design, you can benefit equally well from the use of objects in imperative languages such as C
Although this article has concentrated on the use of C to implement an object-oriented design, there are advantages of using an object-oriented language
If you are interested in object-oriented programming I would suggest playing with a real object-oriented language such as Smalltalk (there is a PD version called 'Little Smalltalk' that I believe is available on various micros including the Archimedes and probably the IBM PC and Macintosh) - even if you still use C to implement your object-oriented designs you will have a much better feel for defining objects from the problem requirements in the first place
Finally, and perhaps most importantly, beware the dogma of object-oriented design
Classic Design Pattern Solutions
A collection of patterns that can be used to describe classic solutions to common
object oriented design problems.
Design Patterns Design patterns form a cohesive language that can be used to describe classic solutions to common object oriented design problems
By using design patterns to solve programming problems, the proper perspective on the design process can be maintained
These pattern discussions, except for the Null and Model-View-Controller patterns are adapted from the classic text, Design Patterns by Gamma, Helm, Johnson and Vlissides (Addison Wesley Longman, 1995
