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,...

Today, business integration software provides a platform to all businesses to perform well in their chosen markets. Business integration software becomes the requirement of every business. There are different sizes of business with different nature and different needs. It can be categorized as small, medium or large businesses. Every business has a different stratum of working. There are several units in each company that has to be effectively maintained. All the data are stored in the computer. Therefore the communication system of the company must support all the elementary channels required in the business. All these are possible only witheffective business integration software. The configuration rules and business integration software usage with other systems in the office must be high-end so that it enables the automation of the business process at the earliest. Importance of Code Generation Code generation software is a basic requirement of several companies. It helps to develop code that can be used in entire framework of business. While choosing the code generation software, it is essential to focus on the designs and techniques. Moreover, the most essential criteria are to choose a design that is manageable. Many enterprises have legacy applications in their computer. This helps to generate code, but now there are better programs and operating systems. The term Commercially available Off-the Shelf (COTS) is not new to those who are involved with computers and it refers to the software and hardware products which are readily available in custom made form and are accessible to the public from the market. The remarkable feature of the COTS products is that they are easy to use and implemented quickly. There are applied in different fields...

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 applications are...

When an organization has taken the initiative to perform a system migration, it is not a decision made lightly. Legacy migrations are not commonly performed because of the cost that the organization incurs. And so after coming to terms and considering all the pros and cons, there is a check list to perform prior to a legacy migration. Firstly, the organization must inquire and decide on the legacy migration method they wish to carry out. There are several legacy migration methods that organizations can choose from; straight migration, migration by extension and upgrade inclusion migration. Should they choose to perform a straight migration, they will be moving the current legacy system as it is, without any upgrades whatsoever to the system. This method of legacy migration is mostly done by an organization that is completely satisfied with their system and how it handles operations. It focuses mostly on improving efficiency in terms of performance of the system and reducing the maintenance costs of the legacy system. Another method of legacy migration is by extension. Regardless of whether the organization is completely satisfied with the current system, there may be a component that cannot be upgraded and thus requires an additional aspect added to the legacy system. With the system running inefficiently, there is cost to the organization. An extension to the system makes the legacy system more cost effective. And finally there is legacy migration with the inclusion of an upgrade. Unlike that of the extension, the features of the legacy system are moved into the new system, and some new features are added on....

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 redundancy. Aside from the fact that...
