Very Large Business Applications
A Very Large Business Application ( VLBA ) is a Business Application (Business Application ), which can be implemented by different types of business application systems, as well as by system landscapes. It supports one or more processes of business application areas such as accounting, human resources, logistics, sales and marketing, at least one is a business process. A VLBA is therefore directly in income and has the support of - a strategic relevance of business processes of an organization - may be subject to cross-company.
Without a VLBA an organization would its core businesses can not meet efficiently. It is a strategic function of the organization onset of a VLBA given for a departure or change of use is associated with great financial, human and organizational effort. In addition VLBAs have no spatial, organizational, cultural or technical limitations.
VLBAs resemble a corporate information system in such a way that they can support multiple operational areas of application and in this case based on several types of business application systems.
VLBAs can be found regardless of size within different organizations in various fields. Systems of Enterprise Resource Planning (ERP ), Supply Chain Management (SCM ) and Customer Relationship Management (CRM ) are examples of a VLBA. Within a supply chain, small and medium-sized enterprises at a VLBA can participate.
With VLBA also an area of research is called beyond. Today's heterogeneous system landscapes and grown, as can be found usually in practice, suffer from the symptom of "spaghetti - integration". It therefore seems appropriate to lift the principles of software engineering to the level of system landscapes, and so to establish a design theory in the sense of a System Landscape Engineering. However, the operation of such landscapes are problems that need to be addressed through research and development. These arise, for example, from the need of automation, lack of theoretical foundation and strategic decisions that push the technical limits of a VLBA and thus make a runnability under constant demands impossible. Through the solution of existing problems arise target models. Similarly, expanding the technological frontier, which VLBAs subsequent generations become the focus. Is the dynamic nature of development of VLBAs can be seen.
