Very Large Business Applications

from Wikipedia, the free encyclopedia

A Very Large Business Application (VLBA) is a business application that can be implemented by different types of business application systems as well as by system landscapes . It supports one or more processes in operational application areas such as accounting , human resources , logistics , sales or marketing , at least one of which is a business process. A VLBA is therefore directly effective and has strategic relevance through the support of - possibly cross-company - business processes of an organization.

Without a VLBA, an organization would not be able to efficiently fulfill its core business. There is a strategic dependency of the implementing organization on a VLBA, because a departure or change of the application is associated with great financial, personnel and organizational effort. In addition, VLBAs have no spatial, organizational, cultural or technical restrictions.

VLBAs are similar to a business information system in that they can support multiple business application areas and in this case are based on multiple types of business application systems.

VLBAs can be found in different areas within different organizations regardless of their size. Systems of Enterprise Resource Planning (ERP), supply chain management (SCM) and customer relationship management (CRM) are examples of a VLBA. Small and medium-sized companies can also participate in a VLBA within a supply chain.

VLBA is also used to designate a research area. Today's heterogeneous and grown system landscapes, as they are usually to be found in operational practice, suffer from the symptom of " spaghetti integration ". It therefore makes sense to raise the principles of software engineering to the level of the system landscape and thus to establish a design theory in the sense of system landscape engineering. But even with the operation of such landscapes, problems arise that need to be remedied through research and development. These result, for example, from the need for automation, a lack of theoretical foundation and strategic decisions that reach the technical limits of a VLBA and thus make it impossible to run under constant requirements. Target models are created by solving existing problems. At the same time, the technological limit is expanding, which means that VLBAs of subsequent generations come into focus. This shows the dynamic character of the development of VLBAs.
