Power builder is an integrated development environment used to create applications. PowerBuilder to .Net is a combination of PowerBuilder and Microsoft’s .Net platform; the latest in software migration that has revolutionized the world of applications development. Though originally designed to compete with Microsoft developed IDE’s, the Power Builder to .Net integration was created to allow continuity for the PowerBuilder project and to take advantage of the .Net platform that many developers are now using to create business critical applications. The PowerBuilder to.Net IDE is preferred by many application developers as it is a fast, cost-effective and easy application development software. The typical PowerBuilder to .Net business application is high performance and data driven. Technology used in PowerBuilder to.Net is also unique in that it continuously evolves to accommodate the latest software advances and business needs. This ability to keep up with advances in VUI (Visual User Interface) advances as well as functionality creates valuable competitive advantage for businesses that use the PowerBuilder to .Net platform. One of the reasons the PowerBuilder to .Net platform is favoured as rapid application development software by developers is its speed and simplicity. This development speed is attributed to the original PowerBuilder to .Net ‘DataWindow’ technology. This function imported from the PowerBuilder Classic version allows developers to use minimal coding to create data rich applications. Thanks to DataWindow, developers using PowerBuilder to .Net only need to use five lines of coding script to apply custom business logic. The simplicity created by the PowerBuilder to .Net technology through its declarative programming environment, coupled with increased levels of abstraction reduces complexities of development...

PowerBuilder has for years been considered the best application development software among RAD softwares. Its main benefits are speed and simplicity, which are offered by its DataWindow component. Unfortunately though, due to advances in technology, programming languages as well as business needs PowerBuilder is falling into obscurity. The results of this are diminished support services as PowerBuilder experts are becoming scarce and a lack of extensibility for Power Builder based applications. This has necessitated migration to modern platforms such as Java and Microsoft .Net platforms. Legacy migrations such as PowerBuilder to Java have their benefits as well as complications. The main benefit that is reaped from the PowerBuilder to Java migration is platform flexibility. Other advantages associated with this migration are both platforms have the same type of look and feel and PowerBuilder to Java has some degree of automation. There is error handling and security as well as near exact replication. As an upgrade, the PowerBuilder to Java migration provides similar services as the PowerBuilder Classic version, just with more efficient technology. As such the Power Builder to Java upgrade should be able to provide the same productivity levels and higher in a modern environment; little to no limitations on the target server platform as well as an open, flexible platform development environment. This means the upgrade should enable application design and creation using the latest software development methods. Maintenance costs should also be reduced. As with any legacy system migration, quite a bit of money and expertise is needed. Further more migrations such as PowerBuilder to Java can be risky and complex as critical business...

The Common Business Oriented Language, abbreviated as COBOL is among the oldest languages used in programming. Created in the late 1950’s most organizations legacy systems are in fact based on COBOL programming. Due to this though, most companies are finding it hard to update their business processes to reflect the changes in technology. The main problem that is associated with using COBOL legacy systems is that it is an expensive platform to maintain, especially since the number of programmers that are familiar with COLBOL keeps reducing each year. Furthermore it prevents companies from being able to standardize their technology as modern software is not compatible with these older platforms. Since rewriting the source code is equally expensive most firms are viewing migration from COBOL to Java as a more viable option. If you’re not entirely convinced to jump on the COBOL to Java bandwagon you can review the other alternatives available and compare the cost and benefits of all the options. Two other methods of dealing with the issues presented by legacy system use are modernization or re-writing. Modernization entails upgrading to the latest program which will standardize coding format and make it easier to maintain code. The drawback of this though is that the firm will continue to incur COBOL maintenance costs and the system still cannot be integrated with modern technologies. Rewriting entails translating COBOL into a modern code, which while the cleanest method to use is very expensive very slow. The beauty of Java as a programming language is that it can run on practically any operating system platform. COBOL to Java migration should be a...

Most organizations run on legacy software systems. Legacy software consists of programs and applications that are essential to the running of the organizations basic functions. Though most of them are outdated as they were written ages ago using programming language that is now considered obsolete, companies can’t simply get rid of them. Scrapping your legacy software in lieu of a more modern version is not a very good idea for a number of reasons: There is a chance that replacement software may not be as good as your legacy system. Furthermore it may take a long time to get used to the new system and its intricacies, time you could be spending to improve on other aspects of your business. Throughout the years in which you have been using your legacy software it has been accumulating knowledge and experience. Switching to a replacement system means also discarding this knowledge. Users of the legacy software may prefer to continue using the old system as they were more familiar with its workings. Switching would mean depriving them of this confidence and it could result in more than a few hang-ups. It is because of these reasons that companies spend into the millions when it comes to maintaining their legacy systems. Aside from the exorbitant costs associated with supporting original legacy software languages, there is a deficiency in both man power and IT systems that can integrate with legacy systems. Since the original programming language for legacy systems is hard to find, most young professionals are unwilling to learn them as it does not exactly one of their career goals. Furthermore legacy...

The acronym “COTS” is used to refer to commercially available off the shelf items sold in both substantial and commercial quantities in the market place. Such items can generally be bought or used under government contact in the exact form or structure as available to the public. For instance, technology related products such as hardware systems, computer software and construction materials all qualify as commercially available off the shelf items. Typically, commercial off-the-shelf (COTS) based software solutions are commonplace for their timely and affordable provision of standardized functionality. Purchasing commercially available off the shelf software is an alternative to in house developments. Such products offer both government institutions and many businesses the chance to make a considerable saving in procurement, maintenance and development of computer software systems. Because COTS generally requires configuration that is developed for specific uses, its employment has been mandated across numerous business and government programs. Commercial Off-the-Shelf (COTS) software solutions have become commonplace in many domains, including establishments such as the military, because they can provide standardized functionality with more responsiveness, a shorter time-to-market and at lower costs than custom made solutions. The main motivation for employing commercially available off the shelf software’s for most businesses is the desire to cut back on overall system cost and development which is achieved since components can be licensed or purchased instead of being constructed from scratch. Another big motivation for using COTS is that doing so reduces long maintenance costs. Some of the advantages of COTS software are: – They are specifically fashioned for business, institution or organizational needs and can be tailored to...

Software conversion also known as computer migration, data migration or software migration is the copying of files from one computer to another computer, usually a newer version. And so, because the user does not want to lose the data and application stored on the “host” computer, they copy the necessary files and applications that are needed. Software conversion can be accomplished by use of an external storage medium such as an external hard disk. However, imagine that you have been asked to transfer data and application of an entire company to the newer machines. That would require more space than the common hard disks can contains. Therefore, looking ahead, certain companies saw this problem and solved it by providing internet storage. This assists users to accomplish software conversion by allowing the needed data and programs to be sent online to a protected server, and so after the machines are changed, they data is downloaded into the new systems. Another method involves using a data cable connection when one needs to perform a software conversion. All the user is required to do is either to send the data to the new computer on a network, or backup the data on the organization’s server (if one is present) then restore it accordingly. Sometimes, a software conversion becomes an unnecessary mission in that the machines that are being upgraded to already come with the necessary programs. However, there are several files perhaps that the user still requires, and so there is less that needs to be moved. If any applications, never the less, there may be a few programs the user needs...
