Implementation Phase The goal of the implementation phase is to implement a system correctly, efficiently, and quickly on a particular set or range of computers, using particular tools and programming languages. The implementation stage is primarily environmental and works with the realities of particular machines, system, language compilers, tools, developers, and clients necessary to translate a design into working code. Just as the design phase may include some analysis efforts approached from a computational standpoint, the implementation phase essentially always includes design efforts. Implementation level design is a reconciliation activity, where in principle executable models, implementation languages and tools, performance requirements, and delivery schedules must finally be combined. All while maintaining correctness, reliability, extensibility, maintainability and related criteria. The first stage of implementation includes many activities. Coding is the first activity. The software developers take the design documents and development tools such as editors, compilers, and debuggers and then start writing software. This is usually the longest phase in the product life cycle. Each developer has to write their own code and collaborate with other developers to make sure that different components can interoperate with each other. In large and complex projects, someone also needs to decide directory hierarchy so that files are stored in appropriate locations. During the development cycle, multiple persons may modify files. If everyone is not following the rules then this may easily break the whole compilation and building process. Writing good comments is very important as all other documents will be lost eventually. The next is testing. System testing involves testing hardware devices, testing and debugging computer programs, and testing information processing procedures. Programs are tested using data that attempt to simulate all conditions that may arise during processing. Program testing usually proceeds from higher to lower levels of program modules until the entire program is tested as a unit. If computer aided software engineering methodologies are used such program testing is minimized because automatically generated program code is more likely to be error free. Installation is a very critical component in the success of an IT project. It is believed that the installation is the best time to educate the customer by working very closely with them during the installation process. This close interaction is ideal for the customer to learn about the equipment being installed, ask questions, and seek advice and tips on operation or administration issues. Installation represents the physical connection of the equipment to customer's existing infrastructure as well as any configuration of the equipment that is required.
Standardize procedures and project management. E.g. use the same language or coding and decoding of software.
This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.
One of the important components of software engineering is the platforms. There are many various types of computing platforms. A few of these include AmigaOS, Linux, Windows, Solaris. These examples are just a few of many different computing platforms. The types of computing platforms can be differentiated into three different categories, which include operating-system examples, software frame work examples, and also hardware examples. Each of the different platforms has slightly different requirements and means of maintenance. Even the required standards for the platforms differentiate depending on which platform being used. Platforms are a vital part of systems and for applications, and are available in many various forms. The basis of this paper is mainly to observe the differences and similarities of four of these platforms. The particular platforms being compared and contrasted with each other include: Linux, Microsoft Windows, UNIX, and Macintosh. The purpose is to look at the purpose of each of these platforms and also to perceive the advantages and disadvantages of each.
Abstract— Software testing is very important element in various product accuracy. Software testing is set of activities conducted with the intent of finding errors in software. It also verifies and validate whether the program is working correctly with no bugs no not. There are basically three levels of testing- Unit, Integration and System. Unit testing referred to as testing in small whereas Integration and System testing are referred to as testing in large. Various testing techniques available for designing of test cases. This paper basically deals with various techniques available to design software testing test cases.
The software testing is the critical element of software quality assurance and represents the Ultimate review of the software design and coding. The main objective of testing is to find an error and to uncover the errors that are not yet discovered.
The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
Interface Testing- This form of testing would be done to make sure that the systems pass data and work fluently together.
Pre-installation step recognizes technological requirements, identifies a proper technology for a particular business with spadework analysis, plans the usage of that chosed technology and evaluates how technology suppliers can meet these. In order not to get
When working on software with a certain group of people, the programmer will tend to talk more on what they for the program. The programmer gets a list of things needed for the software. They test the software and then release to the group. This usually happens when the programmer work independently or a small business. In bigger corporations this will not be as likely.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
Distributed systems are grouping of computers linked through a network that uses software to coordinate their resources to complete a given task. The majority of computer systems in use today are distributed systems. There are limited uses for a singular software application running on an unconnected individual hardware device. A perfect distributed system would appear to be a single unit. However, this ideal system is not practical in real world application due to many environmental components. There are many attributes to consider when designing and implementing distributed systems. Distributed Software Engineering is the implementation of all aspects of software production in the creation of a distributed
The Main purpose of testing is to check that software meets all specified requirements that guided its design and development. There are many types of software testing techniques that can be performed with in software development life cycle. Out of many software testing techniques, Acceptance testing (AT) is the key feature of software implementation. As the acceptance testing mainly constituents that the system should be acceptable by its owner or user it is also called as User Acceptance Testing (UAT). UAT is performed to ensure that the new system meets all the essential user requirements. It is the final testing activity performed by the customer to test for the completeness, correctness and consistency of the
Likewise, in conformity with reports published by Golara Garousi, Computer Scientist and Researcher, software documentation is not only important for the intended audience, but also for other developers, or even select business officials, if applicable (Garousi, 2015). In fact, software documentation is extremely important in conducting further development, maintenance, or even transfers of ownership regarding the program or source code. As an example, a software development team that produces software with inadequate software documentation, or no software documentation at all, could significantly hinder further development of the given program or source code, while generating serious confusion or doubts for the intended audience of the program or source code. Furthermore, inadequate software documentation could seriously obstruct the ability of other developers, or end-users to learn and comprehend the features and functionalities of a given program or source code. In one study, outlining the importance of quality software documentation, Tija Saukuma, Computer Software Analyst, stresses the importance of software documentation for end-users, such as businesses, where quality software documentation could aid in installation, troubleshooting, obtaining general knowledge, along with other applications necessary for the associated software (Saukuma, 2008). Essentially, quality software documentation is truly important for the successful use or operation of a given program or source code, by both developers and
Software testing is the “process of executing a software system to determine whether it matches its specification and executes in its intended environment” (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified. Failures can vary in their nature ranging from wrong output, system crash to systems using too much memory or executing too slowly. These Bugs in software can be due to untested code executed, u...
