On Oracle's official website, Oracle listed in detail the various benefits of obtaining OCP certification. Although it is suspected of selling itself, it is still very reasonable in general.

In general, the IT industry has high requirements for experts and great pressure on professional competition. Whether you are new to this industry or a veteran in the industry, you need to know that their technical background can really attract the attention of employers. At the same time, employers need a standard to help them select those who are truly technically competent. OCP certification can help the IT industry establish selection criteria for specific positions. OCP certification is a valuable, industry-recognized standard that demonstrates the level of knowledge and competence of certificate holders.

Benefits of Oracle certification for technical experts: OCP certification can give you a distinct advantage. OCP certification can show that you have a deep understanding of a certain position and related Oracle products. Becoming an OCP Certified Professional can help you get noticed by more employers and increase your chances of getting the most challenging opportunities in the IT industry. OCP certification experts confirm the value of OCP certification: 97% of OCP believe that they benefit from OCP certification; 89% of OCP believe that after being certified, they are more confident in the position of Oracle expert; 96% of OCP think they will It is recommended that vocational schools (professional college, a form of vocational education commonly found in the United States) provide corresponding courses.

Benefits of Oracle Certification for IT Employers: OCP certification can also help the IT industry's personnel manager in selecting candidates for challenging positions among candidates. For companies that send employees to training every year, certification can guarantee that their training money is not wasted-their employees have acquired the necessary understanding and knowledge. Companies can also combine certification and employee professional development, which can enhance employee loyalty and their performance in professional positions. At the same time, hiring a certified expert can directly increase the company's strength, as shown by a study by International Data Corporation. The study points out that certified experts handle an average of 40% more support calls per day than those who are not certified; companies that hire certified experts are down 49% less than those that do not; The survey shows that in less than 9 months, the cost savings for certified experts exceeds the cost of sending them to train and obtain certification.

First, positioning

Oracle is divided into two major pieces, one is development, and the other is management. The development is mainly to write stored procedures, triggers, and so on, and to use Oracle's Develop tool to do the form. A bit like a programmer, it requires strong logical thinking and creative ability, which I think will be more difficult; management requires a deep understanding of the principles of the oracle database, the ability to manipulate globally and close thinking, and greater responsibility. Because a small mistake will bring down the entire database, the latter value experience more than the former.

Because of the heavy responsibility of database management, few companies are willing to hire someone who is new to oracle to manage the database. For young people who have just graduated, they can choose to do development first, and after a certain experience, transform and do database management. Of course, this depends on the actual situation of each person.

Learning methods

My method is simple: read a book, think, write notes, do experiments, think again, write notes.

After reading the theoretical stuff, calm down and think about it yourself, ask yourself a few more reasons, and then take notes on what you have learned and thoughts; if you can't figure it out or have doubts, do an experiment and think about it How can this be the same, write down the results of the experiment. Thinking and experimenting is to gain a deep understanding of this knowledge point. The process of taking notes is also a process of sorting out your own ideas.

The process of learning is to make a problem from obscure to clear, and then clear to obscure. Each change means that you have learned a new point of knowledge.

The learning process is also the process from point to line, from line to net, and from net to surface. When a point becomes a line, you will always feel suddenly cheerful. When the net comes to you, you are a master

Many netizens, especially beginners, come to the forum to ask questions whenever they encounter a problem. Before you ask, have you checked the books, have you researched them, and have you searched the forum? This is called mental inertia. Answering your questions by others will allow you to understand this knowledge point in a short time without effort, but studying it through your own efforts will not only understand the knowledge point more deeply, but also more importantly, The process improves your ability to solve and analyze problems. Generally speaking, without studying attitude, no matter what you learn, you will not succeed.

Of course, many beginners often come to the forum to ask questions because they have no way to start when they encounter problems, and they don't know where to find information. But I think, when asking a question, is it possible to ask others how to analyze the problem? Where can I find relevant information? What is the answer instead of this question? It is better to teach people to fish.

Third, deep learning

Management: You can take the OCP certificate, have a systematic study of oracle, and then look at Oracle Concepts, oracle online document. STATSPACT, DATAGUARD, TUNING, BACKUP & RECOVER, and more.

Development: For those who want to do Oracle development, after understanding the basic architecture of Oracle, you can focus on PL / SQL and Oracle's development tools. PL / SQL mainly includes how to write SQL statements, how to use Oracle's own functions, how to write stored procedures, stored functions, triggers, and so on. Oracle's development tools are mainly Oracle's own Developer Suite (Oracle Forms Developer and Reports Developer). Learn how to use these tools proficiently.
