We have been involved in the development of a large number of pilot applications to form our own view on object-oriented methods. Although our experiences confirmed the claims about the benefits of object-oriented methods, we identified a number of important obstacles that are not addressed by current methods.

We have been involved in the development of a large number of pilot applications to form our own view on object-oriented methods. Although our experiences confirmed the claims about the benefits of object-oriented methods, we identified a number of important obstacles that are not addressed by current methods. This paper summarizes these obstacles and evaluates them with respect to our pilot applications. The aim of this paper is to make software engineers aware of problems they may encounter during object-oriented development, and to inspire researchers to initiate new research activities.</p><div class="ds-work-card--button-container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--work-card","attachmentId":31860874,"attachmentType":"pdf","workUrl":"https://www.academia.edu/4448291/Obstacles_in_object_oriented_software_development"}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--work-card","attachmentId":31860874,"attachmentType":"pdf","workUrl":"https://www.academia.edu/4448291/Obstacles_in_object_oriented_software_development"}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div><div class="ds-signup-banner-trigger-container"><div class="ds-signup-banner-trigger ds-signup-banner-trigger-control"></div></div><div class="ds-signup-banner ds-signup-banner-control"><div id="ds-signup-banner-close-button"><button class="ds2-5-button ds2-5-button--secondary ds2-5-button--inverse"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">close</span></button></div><div class="ds-signup-banner-ctas"><img src="//a.academia-assets.com/images/academia-logo-capital-white.svg" /><h4 class="ds2-5-heading-serif-sm">Sign up for access to the world's latest research</h4><button class="ds2-5-button ds2-5-button--inverse ds2-5-button--full-width js-swp-download-button" data-signup-modal="{"location":"signup-banner"}">Sign up for free<span class="material-symbols-outlined" style="font-size: 20px" translate="no">arrow_forward</span></button></div><div class="ds-signup-banner-divider"></div><div class="ds-signup-banner-reasons"><div class="ds-signup-banner-reasons-item"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">check</span><span>Get notified about relevant papers</span></div><div class="ds-signup-banner-reasons-item"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">check</span><span>Save papers to use in your research</span></div><div class="ds-signup-banner-reasons-item"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">check</span><span>Join the discussion with peers</span></div><div class="ds-signup-banner-reasons-item"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">check</span><span>Track your impact</span></div></div></div><script>(() => { // Set up signup banner show/hide behavior: // 1.

The road towards an object-oriented approach is described and several object-oriented programming languages are reviewed. Since the object-oriented paradigm promised to revolutionize software development, in the 1990s, demand for object-oriented software systems increased dramatically; consequently, several methodologies have been proposed to support software development based on that paradigm. Also presented are a survey and a classification scheme for object-oriented methodologies.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Brief History of the Object-Oriented Approach","attachmentId":30280254,"attachmentType":"pdf","work_url":"https://www.academia.edu/2227064/A_Brief_History_of_the_Object_Oriented_Approach","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/2227064/A_Brief_History_of_the_Object_Oriented_Approach"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="113049098" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/113049098/The_object_oriented_paradigm">The object-oriented paradigm</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="37715636" href="https://tno.academia.edu/PierreAmerica">Pierre America</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Computing science notes, 1994</p><p class="ds-related-work--abstract ds2-5-body-sm">In this paper we discuss the fundamental concepts present in the object-oriented methodology. First we concentrate on the notion of an object, the key concept in this approach. A (software) object is the abstract representation of a physical or conceptual object. It consists of a name, a specified set of data-elements and methods. Data-elements can have values attached to them. Data-hiding is the feature that certain data and methods can be kept invisible (= hidden) for the outside of an object, thus facilitating its description. Only knowledge on the nature of the visible data-elements and methods is required to make proper use of the object. This is called data-abstraction. A related concept is encapsulation, a technique for achieving both data-hiding and data-abstraction. A class is a template for a number of similar objects. Classes do not prescribe values for the data-elements nor fixed implementations for their methods. A class can be seen as a set of objects that satisfy the same specification for data-elements and method-behavior. An alternative grouping of objects may take place by means of object types, as we will describe. A type is a set of objects that satisfy the same ezternai specification, i.e., specification of the visible data-elements and methods. Thus, a classification via types differs from an ordering into classes, as we shall explain. The notion of type brings along a notion of subtyping. We also discuss different forms of inheritance between classes. By means of inheritance a class can use data-and method-descriptions from another class. We describe, among other things, single inheritance, multiple inheritance and overriding. We also discuss mUltiple preferred inheritance and runtime inheritance. Finally, we show how actual programming can take place in an object oriented approach. For that we need a description of inter-object communication by means of messages. Relevant aspects are: synchronous and asynchronous message passing, scheduling and delegation. The paper concludes with an overview and a number of summarizing remarks. "'This paper originates from Marc van der Kammen's master's thesis "The logic of objects; object oriented programming in a logical perspective". It is the revised version of his chapter 0, which contains an overview of the most important basic notions concerning object-oriented programming.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"The object-oriented paradigm","attachmentId":110113535,"attachmentType":"pdf","work_url":"https://www.academia.edu/113049098/The_object_oriented_paradigm","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/113049098/The_object_oriented_paradigm"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="271915" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/271915/A_Survey_of_Object_Oriented_Concepts">A Survey of Object-Oriented Concepts</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="146184" href="https://unibe-ch.academia.edu/OscarNierstrasz">Oscar Nierstrasz</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Object-Oriented Concepts, Databases and Applications, 1989</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Survey of Object-Oriented Concepts","attachmentId":1189611,"attachmentType":"pdf","work_url":"https://www.academia.edu/271915/A_Survey_of_Object_Oriented_Concepts","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/271915/A_Survey_of_Object_Oriented_Concepts"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="90846577" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/90846577/Object_Oriented_Programming_Approach_A_Panacea_for_Effective_Software_Development">Object Oriented Programming Approach: A Panacea for Effective Software Development</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="218742418" href="https://independent.academia.edu/AfropolitanJournals">Afropolitan Journals</a></div><p class="ds-related-work--metadata ds2-5-body-xs">African Journal of Advanced Sciences and Technology Research, 2022</p><p class="ds-related-work--abstract ds2-5-body-sm">This paper studied object-oriented programming (OOP) as an effective solution approach to software development.

It allows society to delegate special skills to institutions of religion, justice, and the preservation of liberty.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"OBJECT-ORIENTED ANALYSIS AND DESIGN With applications SECOND EDITION","attachmentId":56756916,"attachmentType":"pdf","work_url":"https://www.academia.edu/36807105/OBJECT_ORIENTED_ANALYSIS_AND_DESIGN_With_applications_SECOND_EDITION","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/36807105/OBJECT_ORIENTED_ANALYSIS_AND_DESIGN_With_applications_SECOND_EDITION"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="69211596" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/69211596/A_Study_of_In_depth_Issues_Surrounding_Object_Oriented_Languages_using_Object_Oriented_Design_Patterns">A Study of In-depth Issues Surrounding Object Oriented Languages using Object Oriented Design Patterns</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1138762" href="https://christuniversity.academia.edu/ClarenceTauro">Clarence Tauro</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2013</p><p class="ds-related-work--abstract ds2-5-body-sm">In this competitive world, all enterprises depend on the IT as their active support for various purposes. As a result the software projects are becoming larger and more complex. Hence the developers face challenge of developing the complex software’s more quickly. The best solution to this is the concept of Reuse [1]. Through object oriented analysis pattern it is possible to solve the problems occurring in software development through its reusable capacity [1]. Good OO designs are reusable and stable nature, this provides the ability of this pattern to be used in Other applications which share the same knowledge[7]. Patterns show you how to build systems with good OO design qualities. The main aim of “object oriented analysis pattern ” is to provide expert solution to recurring business problem and to produce more reliable conceptual design. In this paper, we formally give an overview on the state of Object-oriented modeling using patterns and classification of analysis pattern and...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Study of In-depth Issues Surrounding Object Oriented Languages using Object Oriented Design Patterns","attachmentId":79393282,"attachmentType":"pdf","work_url":"https://www.academia.edu/69211596/A_Study_of_In_depth_Issues_Surrounding_Object_Oriented_Languages_using_Object_Oriented_Design_Patterns","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/69211596/A_Study_of_In_depth_Issues_Surrounding_Object_Oriented_Languages_using_Object_Oriented_Design_Patterns"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="125490380" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/125490380/Object_oriented_systems_analysis_and_design">Object-oriented systems analysis and design</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="325421838" href="https://independent.academia.edu/HessamAshrafi">Hessam Ashrafi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2008</p><p class="ds-related-work--abstract ds2-5-body-sm">Orientation 30 1.

The central mechanisms of object-oriented programming appeared with Simula developed more than 30 years ago including class, subclass, virtual function, active object and the first application framework, Class Simulation. The core parts of object-oriented programming should be well understood, but there are still a large number of issues where there is no consensus. The term object-orientation has been applied to many subjects such as: analysis, design implementation, data modeling in databases, and distribution. In this paper the term object-oriented programming is meant to cover all these subjects, since one of the advantages of object-orientation is that it provides a unified approach to these subjects. The issues being discussed in this paper are: modeling versus reuse as the main benefit of object-orientation; the need for a language independent conceptual framework; abstraction mechanisms for suppor...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Open Issues in Object-Oriented Programming","attachmentId":100417515,"attachmentType":"pdf","work_url":"https://www.academia.edu/99286254/Open_Issues_in_Object_Oriented_Programming","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/99286254/Open_Issues_in_Object_Oriented_Programming"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":31860874,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":31860874,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_31860874" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
