Object-oriented analysis and design OOAD is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming , as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality. OOAD in modern software engineering is typically conducted in an iterative and incremental way. The intention is for these to be continuously refined and evolved, driven by key factors like risks and business value.

Object Oriented Analysis and Design: Do We Need More UML in the Classroom

Show all documents This approach is the most common approach to information modeling.. ER diagrams are readily converted into a database implementation. The ERD is especially useful for application in which data and relationships, that govern data, are complex. The ER model consists of the data, object and the relationship that connect data object to one another.

A data object is a representation of any composite information that must be understood by software. For example, car ID. The relationships show how data objects are connected to each other. For e. Analysis of Inconsistencies in Object Oriented Metrics Software Metrics have been proposed for procedural and object oriented paradigms to measure various attributes like complexity, cohesion, software quality, and productivity.

As object oriented analysis and design appears to be at the forefront of soft- ware engineering technologies, many different object - oriented complexity and cohesion metrics have been developed. The aim of the paper is to compare some of the complexity and cohesion metrics and to analyze these metrics and ex- pose their inconsistencies.

The inconsistencies in these methods are exposed by providing various examples. NLP based Object Oriented Analysis and Design from Requirement Specification This paper describes a natural language-based tool which aims at supporting the Analysis stage of software development in an Object - Oriented framework.

This Natural Language Processing technique is to analyze software requirement texts written in English and build an integrated discourse model of the processed text, represented in a Semantic Network.

Requirement analysis determines the user expectation for the application. We propose a method to extract the diagrams from requirement analysis with strong semantic support. The tool can also convert the user modelling information into the blocks of programming source code; Code generation is made available in Java.

As a result the software projects are becoming larger and more complex. 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.

In this paper, we formally give an overview on the state of Object - oriented modeling using patterns and classification of analysis pattern and development on analysis pattern and also the applications of analysis patterns.

The end product will be a professionally produced system design for an organization. Each team will choose the project module. The choice should depend on the ease of access to and cooperation from the department or unit, and on the perceived information systems needs of the organization.

Teams were expected to develop their respective modules based on the Unified Process concepts which include the business modeling, requirement definition, analysis and design activities. Each module chosen by a team required at least six usecases. Each team member is required to work on two usecases. The assignment will be completed in stages. At the end of each stage, each team will submit one portion of the project a "deliverable". All deliverables are to be submitted both electronically as well as a paper copy for instructor comments.

Deliverables at each phase of the project will be required at pre-determined dates. See Figure 2. Teams are expected to follow the deliverable schedule to ensure that the project is completed in the allocated time. Towards the end of the term, teams are expected to present their system design module to the class. The conceptual model derived by the existing object - oriented analysis and design methodology can generate object - oriented programming code through class diagram.

But the consistent analysis and design methodology for security is not being presented [7]. Software engineering Encylopedia entry Software engineering has delivered and is well set to continue to deliver both practical support to software developers and the theoretical frameworks which will allow that practical support to be adopted, used and extended with confidence.

Software engineering innovations take a surprisingly long time to percolate through to every day use [5]. Despite this lag, current software engineering practice is being radically reshaped by object - oriented design methods, design tools with powerful code generation, testing and analysis environments, development patterns, incremental delivery based life-cycles, component models and document management environments, all the product of software engineering.

A vision of the future of software engineering suggests a setting in which developers are able to wire together distributed components and services heterogeneous and sourced over the net having established at an early stage, through rigorous yet easy-to-use formal analysis that the particular configuration will meet the requirements both functional and non-functional. The overall process in which this takes place will have seamless tool support that extends through to change over the system or service life.

Each facet of the resulting system or service will be traceable to and from the originating stakeholders who will be involved throughout the process. Stochastic approach markov chain applied to the analysis and project of the information systems oriented to object The UP foresees four major phases: S1 - Conception, S2 - Elaboration, S3 — Construction and S4 — Transition figure 3 shows the stochastic modeling through the transition diagram, which is a graphical representation of a Markov chain, which aims to control the transition from each state that the process of creation of an object - oriented system development project is encountered.

Iterations occur within each state; a state may have one or more iterations. The term workflows has here the meaning of a set of activities with a common goal. These are the activities for which it must go through when it is in a state, each state can predict the five activities.

The user has participation in all states with more intensity in the design , in the transition state it is clear the risk, being that in this state the implementation happens. The tool mainly focuses on testing design specifications for Object Oriented software. An advantage of testing software specifications as compared to program code is that specifications are generally correct whereas code is flawed.

Moreover, with software engineering principles firmly established in the industry, nowadays, while developing software all the steps of Software Development Life Cycle SDLC are adhered to. For this work, UML specifications are considered. UML has become the defacto standard for analysis and design of Object Oriented software. UML designs created in Rational Rose are used by the tool as input. The main components of this tool are:. The authors have proposed six class-based design metrics for Object.

The CK metrics suite defines class- oriented software metrics that focus on the class and the class hierarchy. Chidamber and Kemerer worked in collaboration with experienced software engineers and collected data from two different commercial projects.

They made some interesting and practically useful observations on when analyzing their results. A design method for object-oriented programming In fact, it is difficult to decide which side gives a correct view. Not only is the boundary between the requirement analysis and the design phase not clearly defined but the boundary between the design and the implementation phase is also not well separated.

As LaLonde et al. This has served to clarify the two activities and create two classes o f people: designers and programmers. In object - oriented systems, the two groups must be integrated; i. If one applies such a view about design and implementation phase, inheritance should be taken care o f in the design phase.

In addition to this, the design method resulting from this research requires that the output of the design phase should be a set o f design specifications. These design specifications should have all the implementation details so that when programmers take away the specifications, they can implement the system with confidence. Therefore, it is decided that working on the inheritance hierarchies should be an activity in the design phase.

Greater the number of children, greater the reuse, since inheritance is a form of reuse. Greater the number of children, the greater the likelihood of improper abstraction of the parent class. If a class has a large number of children, it may be a case of misuse of sub classing. The number of children gives an idea of the potential influence a class has on the design.

If a class has a large number of children, it may require more testing of the methods in that class. Design and implementation of an object-oriented functional language By contrast, functional programming FP is not used extensively in industry, mainly due to perceived low performance, restricted programmer skill base, and poor support for large-scale applications programming there is typically no methodology supporting analysis and design.

However, FP languages can bring major benefits to program development. Furthermore, functional languages have simple syntax and semantics and the key property of referential transparency ensures that encapsulation cannot be breached and programmers can work securely at an appropriate level of abstraction. It refers set of metrics for the object - oriented paradigm.

The two main features used in MOOD metrics are methods and attributes. Methods are used to perform operations of several kinds such as obtaining or modifying the status of objects. The tool mainly focuses on testing design specifications for OO software. UML has become the defacto standard for analysis and design of OO software. International Journal of Computer Science and Mobile Computing media as a website, information seekers can find something that is needed such as ticket purchases at PT.

The process done in ordering tickets online is to register first [1], then consumers get the identity of the buyer such as username and password. After successful registration then the consumer can choose the seat in accordance with his wishes, and after that consumers will get a message into the phone that states to make payment for the ticket [2].

Utilization of internet and website produce good output for its users, because internet and website are communication network without boundary and space, so give facility and ease in completing work [3, 4, 10].

Ease in using internet media to give positive impact to its users and the factor belief between infor mation giver and recipient information. If there is no trust factor, then all activities in the delivery of information will not be easily accepted. Trust is also an important factor in the ongoing sale and purchase of online transactions because trust is essential and is created by direct interaction with the seller personally, or in general the creation of relationships between consumers and vendors [5, 8].

In utilizing the online ticket booking system also by utilizing the application based on the operating system android and iOS, but in this study ticket bookings can still be opened online using mobile devices.

By using mobile devices all activities can be easier for consumers in booking tickets online and also without knowing the time and space limits. As in previous research, mobile commerce has emerged as a vital tool for many firms as smart phones continue to evolve and gain in popularity. It offers customers accessibility, enabling them to purchase products or services at any time and from anywhere [6, 7, 9, 11, 12].

Where the UML model to be used in this research is use case diagram. International Journal of Emerging Technology and Advanced Engineering Software Metrics have been proposed for procedural and object oriented paradigms to measure various attributes like complexity, cohesion, software quality, and productivity.

As object oriented analysis and design appears to be at the forefront of software engineering technologies, many different object - oriented complexity and cohesion metrics have been developed [9]. The concept of object - oriented programming very much relates the design and implementation phases of software system, which is directly related to the usability of system. CK metrics were defined to measure design complexity in relation to their impact on quality attributes such as functionality, reliability, usability, maintainability etc [21].

Я рассказал о нем полицейскому. Я отказался взять кольцо, а эта фашистская свинья его схватила. Беккер убрал блокнот и ручку. Игра в шарады закончилась. Дело принимает совсем дурной оборот. - Итак, кольцо взял немец. - Верно.

Он был уже совсем .

Рука консьержа только что покинула ячейку под номером 301. Беккер поблагодарил его и быстро зашагал, ища глазами лифт. Туда и обратно, - повторил он мысленно. ГЛАВА 31 Сьюзан вернулась в Третий узел.

Но когда он начал подниматься на следующую ступеньку, не выпуская Сьюзан из рук, произошло нечто неожиданное. За спиной у него послышался какой-то звук. Он замер, чувствуя мощный прилив адреналина. Неужели Стратмор каким-то образом проскользнул наверх.

Проваливай и умри. Он не верил своим глазам. Немец не хотел его оскорбить, он пытался помочь.
