Maintainable Code

                Maintainable code: everybody wants it, very few modernization customers get it. But rigorously defining what is maintainable code is somewhat difficult. However, there are some good guidelines to go by: 1. Maintainable code for web business systems does NOT have the same structure as your legacy mainframe programs. In Natural and COBOL and MAPPER, for example, it is possible to mix the business logic in with the presentation or view (the screens and reports). That’s not how we write programs for the web, and forcing the Java or .NET developers to forget most of the best practices they learned in school and follow the unstructured ramblings of a 30-year-old programming hegira is NOT what we mean by maintainable. Maintainable code is properly structured down to the class level — it’s not just a matter of throwing a bunch of spaghetti into the “spaghetti layer” and calling the result maintainable. 2. Maintainable code has meaningful comments — not just duplicating what was in the legacy system, because that is only useful if you also duplicated the structure of the legacy application. Otherwise, the comments would be in the wrong place, wouldn’t they? The comments should tell the programmer about the Java or .NET programming choices that were made and why they were made. 3. Maintainable code uses modern frameworks like Struts 2 and Hibernate and the facilities of Visual Studio 2010. It may not use the absolute latest versions, but it should not use versions that are obsolete or are on the verge of becoming so. Vendors who have translators that were...

Legacy system integration

                  In the world of business legacy system integration is the new black. The basic processes information systems structure of many enterprises is managed via legacy software, a mixed blessing as most managers would put it. Based on technology that has long since passed the modern stage, legacy software can be quite a challenge to deal with. Unlike other technology that can probably be upgraded without much fuss an organizations legacy system is that one integral pillar in its IT infrastructure that can not be moved lest the whole structure fall apart. This is a source of dilemma for many a manager.   Aside from catering to their consumer’s immediate basic needs, businesses also need to keep in mind their future desires. As IT evolves so do the technological needs of the masses a fact that organizations can not ignore. Thus comes in the managers dilemma, how to reconcile the information needs of the customer with the technological capabilities of the business. You are basically running an organization whose processes are run by software that might be older than your first child yet you need to furnish your tech-savvy customers with data compatible with their modern systems. Legacy system integration is one way to ensure that you can keep your integral system in tact while incorporating the use of modern applications. The discovery of the benefits of legacy system integration has led to a significant rise in organizational spending in this sector. Though legacy system integration could possibly cost the organization millions of dollars, in the current environment of flat-lining IT...

System Integration – When The Old Meets The New

                    System integration, also simply known as SI, is the process of putting in a new system, which can still relate and communicate with the previous system or systems, be it, or they, simple or exceedingly complicated. System integration is an arduous process, which needs a lot of setting up and development, and an implementation and optimization phase. The one objective of System integration is to solve the problems that are experienced, which cannot be solved by the existing systems. Examples of the different types of System integration are management system integration, business system integration and even software system integration.   When attempting to apply software system integration, the work the current system does is first established, that is, the problems that the current system solves. When the shortcomings of the system in relation to the problem solving area are discovered, the designers of the new system must then justify how the system they wish to introduce will aid and whether it is financially viable. The new system must create profits for the organisation or at least stem losses.   Management system integration brings to light new methods to reach objectives and makes use of untapped potential the previous system could not originally make use of. For example, providing wireless services to the staff that is on the field, allow for timely feedback, for example if a survey in a remote area. In this way the decision makers can make quick verdicts to the direction they should follow. This form system integration is both effective and efficient.     To...

The General Points of Software Conversion

          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...

The Existence Of Legacy Software Through Decades

        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: 1.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. 2.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. 3.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...
