oracle ocp

After completing the last exam at noon, I always thought that I would be excited after I passed the exam. Who knows that my performance was calm and I was surprised, as if I thought it was something else. For a long time, there have been two OCP goals: one is to make a summary of Oracle over the past six years; the other is to verify that after so many years of work, I still have not lost my self-learning a

Introduction to OCP (OCP -- open-closed principle ):Software entities (classes, modules, functions, etc.) shocould be open for extension, but closed for modification.

The open-close principle (OCP) is called the cornerstone of OOD and is one of the most important principles of Ood. This principle was proposed by Master Bertrand Meyer in 1988 (Khan, at that time I am afraid few people in China know Oo, or even what the computer is): software entities shocould be open for extension, but closed for modification. How simple ?! This principle means that the software should be developed for expansion, and the modificatio

Software composition entities should be extensible, but cannot be modified. [Software entities shocould be open for extension, yet closed for Modification ] Openness-closure rules 1. The open-closed principle assumes that we should try to design modules that never need to be changed. 2. We can add newCodeTo expand the behavior of the system. We cannot modify the existing code. 3. OCP-compliant modules must meet two standards: 4. scalability, t

9th OCP: Open-closed principleSoftware entities (classes, modules, functions, and so on) should be extensible, but not modifiable.9.1 OCP OverviewModules designed to follow the open-closed principle have two main features:(1) is open for extensions (open for extension). This means that the behavior of the module can be extended. When the requirements of the application change, we can extend the module to th

Calculation method: Select name, (1-(physical_reads/(db_block_gets + consistent_gets) * 100 h_ratio from V $ buffer_pool_statistics; The hit rate, which is used to measure the performance of a database, is already an old man's experience. Now it's all through the Oracle wait interface. The hit rate can be used as a reference, but the hit rate is not necessarily related to the system performance. In addition, the single-view hit rate cannot be descr

key is abstraction. In C ++, you can create a fixed abstract body that can describe any possible behavior. This abstract body is the abstract base class, and a group of people can act as a possible derived class. This base class does not need to be modified. The member methods (interfaces) in the class are declared as pure virtual functions. The specific implementation can be implemented, changed, and extended in the derived class. Using OCP, you ca
