SAP is an acronym for Systems, Applications and Products in Data Processing. It is an enterprise resource planning (ERP) software product capable of integrating multiple business applications, with each application representing a specific business area.
SAP applications, built around the latest R/3 system, provide the capability to manage financial, asset, and cost accounting, production operations and materials, personnel, plants, and archived documents.
According to the SAP website, SAP is the world's third largest independent software company. More than 12 million people worldwide work with SAP applications each day.
