Table per class hierarchy<br /> 2. Table per subclass<br />3. Table per concrete class </p> <p> Each of these have it's strengths and limitations and we will make short review of them and present simple examples based on following class hierarchy: </p> http://www.croz.net/index.php/eng/tech_blog/integration_of_spring_ioc_container_into_eclipse_rcp <p> One of the projects CROZ is currently participating in is dedicated to the production of Rich Client Application. Eclipse Rich Client Platform (Eclipse RCP) has been chosen as a platform for the production of client, whose main characteristic is that it enables XML configuration of user interface. The platform automatically manages various visual elements such as menus, toolbars, view or editor frames etc. </p>
