An entity bean represents persistent global data from the database; a session bean represents transient user-specific data that will die when the user disconnects (ends his session). Generally, the session beans implement business methods (e.g. Bank.transferFunds) that call entity beans (e.g. Account.deposit, Account.withdraw). A message-driven bean is an enterprise bean that allows J2EE applications to process messages asynchronously. It acts as a JMS message listener, which is similar to an event listener except that it receives messages instead of events. The messages may be sent by any J2EE component--an application client, another enterprise bean, or a Web component--or by a JMS application or system that does not use J2EE technology.

Difference between turbocharger and supercharger?
A turbocharger is driven by the exhaust from the engine. A supercharger is belt driven off the engine.
What is the main difference between turbocharger and supercharger?
A "Turbocharger" is driven by exhaust gas. A "Supercharger" is driven mechanically by the engine.
What is the difference between a driver gear and a driven gear?
The driver gear has the input torque, and the driven gear has the output torque.
What is the difference between command driven software and menu driven softwares?
People use menus and computers use commands.
What is the difference between under driven and over driven superchargers r?
Over driven blowers are geared to spin higher rpm then the motors actual rpm. Vise versa for Under driven.
What is the difference between a driving and driven dimension?
Driving Dimension: the geometry is controlled by the dimension. Driven Dimension: the dimension is controlled by the geometry.
What is the difference between a super and turbo charger?
supercharger is belt/gear driven of the motor, the turbocharger is driven by exhaust gases from the exhaust.
What is the difference between Screw driven and hydraulic driven tensile testers?
A screw drive is a screw mechanism that moves and hydraulics is a fluid pressure system
What is the difference between data driven DSS and model driven DSS?
Model data driven user interacts primarily with a mathematical model and its results while data driven DSS is user interacts primarily with the data
What is the difference between turbocharger and supercharger?
A supercharger runs off a belt driven directly from the engine where as the turbo runs off a belt driven by a fan in the exhaust
What is the difference between a model-driven and data-driven DSS?
A model-driven DSS relies on mathematical or statistical models to analyze data and make predictions, while a data-driven DSS uses historical and real-time data to generate insights and support decision-making without relying heavily on predefined models. Model-driven DSS are more structured and use algorithms to process data, while data-driven DSS focus on exploring patterns and trends in data to inform decisions.
What is a stateless session beans?
A stateless session bean is a type of enterprise bean in Java EE that doesn't maintain any conversational state with clients. Each client request is treated independently, and the server can choose any available instance of the stateless session bean to handle the request. Statelessness allows for efficient use of resources and parallel processing since the server doesn't have to keep track of the state of each client.
