PostERP itself is a business information system development and execution framework.

Information systems developers and IT personnel can perpetually enhance and customize PostERP to meet the requirements of their customers and organizations:

creating data entry and query screens
creating reports
designing business logic processors
designing data quick views

The newly created functionalities are truly seamlessly integrated into the existing system - end users do not have to update their client program to use the new functionalities. Most system updates only require end users to refresh screens or sign out PostERP and back in to use the new functionalities.

PostERP is a database driven business information system. All menus, screens, report templates, business logic, etc. are stored in database. Database drives user interface and executes business logic.

Please follow these guidelines to avoid clash with Tera Rows's design:

Include _ in new function names. Examples:f_120(), f_143().
Include _ in new rule names. Examples:r_120, r_143.
