PowerBuilder 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 PowerBuilder 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 ‘Data Window’ 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 and thus...

PowerBuilder has for years been considered the best application development software among RAD software’s. Its main benefits are speed and simplicity, which are offered by its Data Window 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 applications...

Code generation is a technique that is used in the development of applications. There are many types of code generators on the market, each with their unique capabilities. Visual basic code generator is currently the favourite among programmers. This rapid application development tool is generally used to create windows applications. A task it efficiently completes in a short period of time. The basic task of the visual basic code generator is to convert source code data from intermediate language form into a language that can easily be read and enacted by a computer. Code generators such as the visual basic code generator can normally perform dual functions. Aside from intermediate representation conversion, they also try to improve on the code. This optimization can be pursued on the instructional level; where the generator opts for either faster or fewer instructions. It can also be pursued at the more advanced stage through exploitation of available registers and avoidance and elimination of redundant computations. The typical process that the visual basic code generator goes through includes selection, scheduling, allocation and debugging. At the first two stages of the process, the visual basic code generator chooses the set of instructions that it is going to implement. It then determines the order in which these instructions are to be executed. This step could also contribute in terms of speed optimization; especially in the case of pipe-lined machines. In the third step, allocation refers to the collection of associated variables to the available processor register. The final stage of the visual basic code generator is the debugging process. This ensures that there is no data...

Visual basics software is programming software created by Microsoft to aid in the development of programs and applications. The .NET framework is also a Microsoft windows creation designed specifically for use in applications developed on a windows platform. It is basically a large base class library that makes it possible for language interoperability to take place (i.e.: it allows each programming language, in its framework to use codes written in other programming languages). The VB to .NET integration promises to revolutionize program and application development by optimizing the individual functions of visual basics and .NET framework software. VB to .NET is basically an introduction of various syntactical changes and migration to the visual basics programming software. In fact, these VB to .NET features may make it a bit harder to acclimatize, for programmers who started of using Quick basic and GW basic. Though it was easier to upgrade from these program builders to MS visual basic while building up on basic programming knowledge, an upgrade from VB to .NET will not be so simple. This new program has optimized programming by altering coding rules; increasing the number of low-level constructs that are exposed and enforcing a number of programming practices. The major change visible in the VB to .NET program is the IDE. The Integrated Development Environment in this upgraded version presents differences in interfaces. The property page design for the Active X design for instance has been replaced by a property grid display. That said though, VB to .NET still retains the options available in the visual basics software; just displayed in an easier and more flexible manner....

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 fit respective individual...
