A role is a collection of privileges that can be granted to one or more users or other roles. Roles help you grant and manage sets of privileges for various categories of users,
For most business applications, RBAC is superior to ACL in terms of security and administrative overhead. ACL is better suited for implementing security at the individual user level and for low-level data, while RBAC better serves a company-wide security system with an overseeing administrator.

A style of coding where a program's overall flow of execution is dictated by events. • The program loads, then waits for user input events. • As each event occurs, the program runs particular code to respond. • The overall flow of what code is executed is determined by the series of events that occur • Contrast with application- or algorithm-driven control where program expects input data in a pre-determined order and timing – Typical of large non-GUI applications like web crawling, payroll, batch simulation
component; can be "handled" to create interactive components.
– To handle an event, attach a listener to a component.
– The listener will be notified when the event occurs (e.g. button click).
