The five principles of OO refer to SRP, OCP, LSP, DIP, ISP.Open Closed Principle is the most basic design principle in the Java world, which guides how we build a stable and flexible system.Defined:A software entity such as classes, modules, and functions should be open to extensions and closed for modification.Softeware entities like classes,modules and functions should is open for extension but closed for modifications.The opening and closing princi

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 ability, this meaning should be far greater th

I finally completed all the OCP DBA courses. Tired! In general, Oracle certification is worth the test. I have a ccnp and MCSE certificate, but after passing the DBA examination, I feel that I have not only deepened my understanding of modern databases, but also enriched the knowledge structure of computer science. In my opinion, Oracle databases even have some operating system functions. There are quite a few things to remember about Oracle exams.

Design principles (1) "Open-Close" principles (OCP) The cornerstone of classical mechanics is Newton's three major laws. The first cornerstone of object-oriented reusable design is the so-called Open-Closed Principle (OCP ).I. What is the principle of opening/closing? The principle of "open-close" is that a software entity should be open to expansion and closed to modification. This principle was first prop

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure th

Oracle OCP Notes (31) using the Flashback featureOracle's flashback feature is supported by one of 3 database architectures: Undo data, Flashback recovery area, and Recycle Bin.Undoing data in the undo Tablespace not only supports transaction rollback, but also most of the flashback table operations. Flashback Data Archives allows querying a previous version of a table row, which provides a zone in one or more table spaces outside of the undo tablespa

I have not written any new logs for 20 days. Sorry, I am very concerned about this blog. We have prepared for three months since March. We have attended Oracle 9i training these days and successfully passed all four OCP courses. Although it takes more than a month to get the certificate, you can put your mind down for the moment. The current work is not directly related to Oracle. The first test is to obtain a certificate (I have never been certified

traveler and the method of arriving is very close, and the specific way to arriving is a low level problem. The above problems and implementation are a common method to achieve the [open and closed principle]-The Policy mode. There is also a common implementation method: Template Method. In fact, the essence of these two methods is the combination of object-oriented methods. And inheritance. We have learned how to encapsulate changes. How can we encapsulate changes?

Open-closed principle Software"Open-Close principle" in Design" This principle was first proposed by Bertrand Meyer.Entities shocould be open for extension, but closedModification. It means that a software entity should be open to extensions and closed to modifications. That is to say, when designing a module, we should enable this module before it is not modified.Extension. In other words, you do not need to modify the source code.To change the behavior of this module. Satisfying the
