This article does not introduce Ruby's basic syntax much, but only implements Ruby's OO application once. It also records my understanding of Ruby's Oo. In addition, we will not repeat the ruby coding standards here. The written code should follow the ruby coding standards as much as possible. First, create a person class:# Person. Rb # Defines a Class person # Defines the accessor of the attribute and enc

Because of the use of multi-threading, you can not use the first two ways, the request all input and then the related calculation, need to run side of the calculation, so abandoned the first two architectures, basically re-start planning this job.

Control Hibernate's Reference title is called: the Java-compliant O/R persistence, which reveals the major problem with the current three-tier structure, namely, the three-tier unification. So far, it is still difficult to implement the "Master-detail" and "lookup" user interaction in the C/S mode in the Web interface. The current common Web application structure contains Web Browser/application server/database. Database occupies the mainstream is still the classic E/R model, which is based on
