What is Integration?
The process of linking together different computing systems and software applications physically or functionally, to act as a coordinated whole.
The system integrator integrates discrete systems utilizing a variety of techniques such as computer networking, enterprise application integration, business process management or manual programming.
Why Systems Need To Be Integrated?
Today there is a rich and diverse choice of software selection available for almost every business domain. These softwares’ have a huge amount of processing capabilities. However, these software applications are like ‘islands of processing systems’ even within an organization and across business boundaries. One of the challenges of modern software development is that the current methods are no longer able to fulfil the requirements for the development of compound systems with multiple and unstable system requirements. When there are more than one system, additional efforts are needed to integrate the systems. When there are more than one group of developers involved, the overall view of the system is bound to be neglected. All these problems can be grouped together as the problems of software development today, viewed from the engineering aspect.
In order to meet the challenges presented by today’s competitive atmosphere, organizations need the ability to solve problems that cannot be solved on its own. Businesses today need a global, an open and distributed computational capability. In other words, the demand is for a large scale, complex and integrated systems.
