1. Business applications in ERP systems split features into context-specific groups to make the system easier to use. Applications are defined based on a user's role, like sales, purchasing, or accounting.
2. Features are organized into menus tailored for each application/role. For example, a purchasing application would include menus for purchase orders, suppliers, and receiving inventory. Common features like contacts are also accessible across applications.
3. Configuration wizards help users install modules and set up the system for their business when creating a new database. Wizards are application-specific and follow common layout guidelines.
