Save-update: cascade storage (if the sub-object is updated after load, it will also be updated). However, it will not be deleted in cascade mode.Delete: cascade deletion, but does not have level-level joint warranty and updateAll-delete-orphan: when the parent-child relationship is removed, sub-objects that do not belong to the parent object are automatically del

more than one end, then someone asked, many-to-many on both sides are more, inverse exactly where? In fact, hibernate establishes many-to-many relationships and separates them into two one-to-many relationships, connecting a connection table in the middle. So the general existence of a one-to-many relationship, it can also be said: A pair of many is the basic component of many.Cascade has five options: All, delete, None,save-update,delete-orphan; All: Associate operations in all cases. None: As

Learning hibernate when the concept of cascade relationship is always unclear, especially cascade, inverse silly confused. The following is a simple example of how to use the sample.Preparatory work:Start by creating a database with two new tables:Classroom Table classes (field here Province)Student Table student (field here Province)The classroom is a one-to-many relationship with students. then create a n

Cascade is connected to other hubs through a port of the hub. For example, a UPLINK port of the hub is used to connect to another normal port, and a stack is connected through the backplane of the hub, it is a chip-level connection. For example, the stacking of two 24-port switches is like a 48-port switch. The advantage is that there is no bottleneck. Stack and Uplink are two ways to connect multiple switches or hubs. Their main purpose is to increas

PrefaceCMS, full name concurrent low Pause Collector, is a new GC algorithm introduced by the jdk1.4 later version, which has been further improved in Jdk5 and JDK6, and its main fit scenario is that the need for response time is greater than the throughput requirements. The ability to tolerate garbage collection threads and application threads to share processor resources, and to apply applications where there are more long-life-cycle objects. CMS is

CMS overviewFor the website CMS system, PHP-based is the mainstream, such as Drupal/joomla in the mainstream virtual machine providers are standard configuration, is also widely used.But if you have a Java team, or if the project goal is to build a content management system that the enterprise network uses, then choosing a Java-based CMS system is appropriate.PHP

OPEN CASCADE multiple Variable Function[Email protected]Abstract. Multiple variable function with gradient and Hessian matrix are very very import in OPEN CASCADE optimization algorithms. In order to understand these optimization algorithm better, let's study some basic knowledge about Gradient, Hessian Matri X.Key Words. Multiple Variable Function, Gradient, Hessian Matrix, optimization algorithm,1. Introd

Writing today, when configuring a relationship, the cascade is then configured, with a value of false. Foggy, the result is very sad urge, has started on the error, made me, and then carefully check found that the original is cascade in doing that. Now summarize. By the way, review the inverse.1.cascade Cascade, with i

Inverse propertyInverse Property: Indicates whether control is transferred . True: Control has been transferred "the current party has no control" False: Control is not transferred "the current party has control" The inverse attribute is useful when maintaining an association relationship . This attribute can only be used on one side! The default value for the inverse property is Fasle, which means that the current party has control over theTake a look at some aspects of how in
