Enterprise Resource Planning (ERP) describes the entrepreneurial task of planning and controlling resources such as capital, personnel, operating resources, materials, information and communication technology, IT systems in a timely manner and in line with the company's needs. The aim is to ensure an efficient operational value-added process and a constantly optimised control of the entrepreneurial and operational processes [Source: Wikipedia].
Modern, integrated ERP systems, such as Microsoft Dynamics 365 Business Central / Dynamics NAV, which was developed especially for medium-sized companies, are able to represent the complete business processes in a holistic system. This avoids individual "data islands".
