ERP is used for the phrase Enterprise resource planning. An Enterprise Resource Planning system or ERP integrates or attempts to integrate all data and processes of an organization into a single unified system. A typical ERP system will use multiple components of computer software and hardware to achieve integration. A key ingredient of most ERP systems is the use of a single, unified database to store data for various system modules. The term ERP originally implied systems designed to plan the utilization of enterprise-wide resources. Although the acronym ERP originated in the manufacturing environment, today`s use of the term ERP systems has a much broader scope. ERP systems typically attempt to cover all basic functions of an organization, regardless of an organization`s business or charter. Business, non-profit organizations, non-governmental organizations, governments, and other large entities utilize ERP systems. Additionally, it may be noted that to be considered an ERP system, a software package generally would only need to provide functionality in a single package that would normally be covered by two or more systems. Technically, a software package that provides both Payroll and Accounting functions would be considered an ERP software package. However, the term is typically reserved for larger and more broadly based applications. The introduction of an ERP system to replace two or more independent applications eliminates the need for external interfaces previously required between systems. This also provides additional benefits that range from standardization and lower maintenance to easier and greater reporting capabilities, as all data is typically kept in one database. Examples of modules in an ERP, which formerly would have been stand-alone applications, include manufacturing, supply chain, financials, and CRM, human resources, and warehouse management. Overall, ERP is basically a broad term specifically used for any commercial software that helps in building and organizing a database, which can have many advantages.
