Organizations use a standard set of steps, called system development methodology to develop and support their information systems. Like many processes, the development of information systems often follows a life cycle. For example, a commercial product such as a Nike sneaker or a Honda car follows a life cycle; it is created, tested and introduced to the market. Its sales increase, peak and decline. Finally, the product is removed from the market and is replaced with something else. Many options exist for developing information systems, but the most common methodology for system development in many organizations is system development life cycle. However, it is important to know other alternative development methodology available in order to...

...The V Model The V-Model has proven very popular over recent years and has probably replaced the Waterfall Model as the established model of software development. It is interesting to consider that the V-Model could not have existed without the prior experiences gained from usage of the Waterfall Model. If the Waterfall Model is the stern father then the V-Model is the popular son. Delve deeper into its usage and application, however, and one sees that it is not a panacea for all software development ills. Consider the representation of the V-Model below: The V-Model You can take the V-Model as a Waterfall Model snapped in the middle and bent upwards. You then have two 'stalks'; in broad terms, the left stalk represents design activities and the right stalk represents test activities. The flow is from the top left point of the 'vee' where the Statement Of the User Propblem (SOUP) is defined, down to the vertex where code is created and unit tested, up to the top right point of the 'vee' where the end-user validates the software against the original needs as defined by the SOUP. Whereas the Waterfall Model represents a series of sequential steps, the V-Model recognises the increasing importance of testing in the lifecycle. Testing, in the form of planning and review of requirement specifications and design specifications, starts right at the beginning of the lifecycle, unlike the older model where test activities are started further down the line . SOUP & User Acceptance...

...Solutions 1. Describe and compare the six sources of software. The six sources of software identified in the textbook are: (1) information technology services firms, (2) packaged software providers, (3) vendors of enterprise solution software, (4) application service providers and managed service providers, (5) open-source software, and (6) in-house development. IT services firms help companies develop custom information systems for internal use; they develop, host, and run applications for customers; or they provide other services. An IT services firm may be chosen if the system can’t be developed internally or requires customer support. Packaged software providers are companies that produce software exclusively, like Microsoft or Intuit, and are preferable if the task needing the system is generic. Vendors of enterprise solution software create a system that is composed of a series of integrated modules. Each module supports a business function, such as accounting, or human resources. ERP systems may be appropriate if a complete system is required that can cross functional boundaries. A more intense option for larger, more customizable solutions are Managed service providers who can provide more services than application service providers. ASPs and MSPs may be appropriate when instant access to an application is desired, and in the case of ASPs, when the task is generic. Open-source software is a type of software that is developed by a community of interested people...

...Chad Nash Advantages and Disadvantages of Windows XP Windows XP was introduced as a significant upgrade to Windows 98 and Windows Millennium. After Microsoft brought out MS-DOS in the 1980's it developed its futuristic operating system - Windows. Newer versions of this OS were developed over the years, including the out bringing of Windows NT (New Technology) which was aimed at business users and computer servers. After numerous incarnations of the Windows operating system, including Windows 95, 98 and the much criticized Windows Millennium, the XP system was released October 25, 2001.Windows XP has much in common with the singularities and also engineering of Windows 2000. In fundamentals XP was created to"bridge the two architectures (NT and Windows 9x--or DOS) into a single common operating system." Windows 2000 was based on Windows NT technology; as far as Millennium (ME) was created from Windows 9x technology. The NT operating system was much more honorable than the other versions before the o of Windows and accordingly Microsoft decided to choose this technology as the infrastructer for XP. XP was put out in two basic versions - The home and the professional version. The basic inequality between the two versions is that the up to speed version places more significance on security. It also has the efficiency to encrypt files and data and has support for multiprocessor systems. ( Lanyon P.) Windows XP was developed to on the problems and inconsistencies in the ME system...

...[pic] Reverse Engineering a New Trend in Manufacturing [pic] Authors T.Dhamotharakumar* N.S.Ramesh* dhamotharan007@gmail.com nsrmechanical@gmail.com * Under graduate Student, K.S.R. College of Engineering, Tiruchengode Department of Mechanical Engineering [pic] Abstract With the significant capital investment in new equipment being placed into out years, more systems need to be maintained in their present condition for longer periods of time. There are often gaps in the technical support information needed to maintain a system built from older designs using outmoded or updated techniques or materials. In some situations, designers give a shape to their ideas by using clay, plaster, wood, or foam rubber, but a CAD model is needed to enable the manufacturing of the part. As products become more organic in shape, designing in CAD may be challenging or impossible. There is no guarantee that the CAD model will be acceptably close to the sculpted model. Reverse engineering provides a solution to this problem because the physical model is the source of information for the CAD model. This is also referred to as the part-to-CAD process. "Reverse Engineering is the process of taking a finished product and reconstructing design data in a format from which new parts or molds can be produced."-The Society of Manufacturing Engineers Key Words: Reverse Engineering, CAD, Modeling and manufacturing. ...
