Enterprise application software

"There are three main kinds of EAS. . . . Some EAS programs are mass market PC-based applications of fairly limited 'functionality' (meaning capability). Other EAS programs are developed by or for a specific enterprise and its particular needs; . . . The third, intermediate category of EAS [is] enterprise resource planning (ERP) system software. ERP is packaged software that integrates most of an entity's data across all or most of the entity's activities.”
