Summary of my career: how to learn Oracle well

 


I also do not want to guide you how to learn, or how to develop, I just want to put some of my ideas and experience to say, we refer to, or for reference, or a smile or too. In fact, whether to learn Oracle, or learn something else, the basic methods and ideas are consistent, I do not want everyone to learn Oracle, and the so-called 360 lines, the line of the champion, I just hope that in different industries, we can make a difference.
I have a list of points to focus on here.
1. Determine direction and interest
To determine the direction is a very important issue, I also graduated a year after the basic determination of the direction, but if the direction is not confirmed, then the future development is very easy to fall into the path of confusion, many people, after graduation frequent replacement work, but also frequent change of work content, but just do not know what they want to do; , this thing interested, learn a period of time, later, found that things interested, and learn for a while, after a long time, maybe he found that nothing has learned.
After having a direction, still need to be interested in, I also see some people, the purpose of choosing a direction is only to say that this work is more stable, higher wages, in fact, any work done well, can get high wages, but, if only because of money to do this work, you may become very tired. The interest is very important, determines you in this direction studies, the study progress speed, moreover, also is whether you finally really can learn this direction the power.
As for the perception, this is different from the person, or say, this is the day after tomorrow, but the perception of this thing can be made up by good learning methods, the so-called said, frequently can make up the frustration is this truth, this we can learn how to discuss.
Finally, you may want to think about whether you are really fit for the job, I also see some people, ask them why to change jobs, the reason is often said, the original work to often overtime, or often travel, very hard, in fact, I often remind him, if do Oracle, do DBA, may also face frequent overtime, often go to the computer room Because there are some jobs you can't do during the day. If you want to do this job, you'd better understand the job first.
2. How to Learn
How to study, I believe a lot of people have their own way, I only emphasize my method here
More thinking, more practice, more summary
More than one time to see a lot of people, a simple question, also do not consult the data, also do not search the Internet, posted to the forum to ask, or MSN. When confronted with a problem, we first try to solve it ourselves, think more about the cause of the problem, look at the error message, more to search for a similar error, I have more than once encountered someone in the error message is very obvious, such as the system prompts do not have permissions to create files, still there have been asked, why I can not create a file AH.
In addition, in the ordinary learning process, to more hands-on practice, a lot of people, the theory is a good study, ask the very well, but, if he to do a thing, it is a little silly, do not know where to start, or is, the usual learning things, do not know how to use, this type of person, is Yangaoshoudi, Or the Gaofendineng of Chinese-style exams. In fact, in theory and practice, now more people, more companies pay more attention to practical knowledge.
Finally, is to sum up, the so-called good memory than a rotten pen, if you form a summary habit, then, a lot of knowledge, you may not normally use, but, you really need to use, your summary may be effective. More than one time to see a lot of people, in the real need to deal with urgent problems, everywhere in the question, can be on the Internet ah, I want to check the Internet, I know the internet to check the problem of course is good, then, if you usually have a perfect summary, or this time, you go , we have finished the work.
3. Learning process
About the process of learning, more than once someone talked about, here can first quote Eygle words:
Wang Guowei in his "Human CI" has summed up for the study of the three realms, I apply here:
The ancient and modern into the big cause, the great scholars, without passing through three kinds of realm.
Last night the West wind was green. Alone on the high-rise, look at the Tianya road. "This first realm also.
"Shiriko end not regret, for Iraq to eliminate people haggard." "This second realm is also.
"The public in search of his 1100 degrees, suddenly looking back, the person is in the lights dim place." "This third realm also.
He quoted Mr. Wang Guowei's words, the Oracle's study is divided into three kinds of realm that must go through, it is estimated that a lot of people who learn to have the same feeling, at the outset, I saw such a word, also have the same feeling, this, when I learn the car, once again proved. In fact, not only to learn Oracle, learning everything is the same, may have the following way forward: code:

.

as shown in the figure, after studying for some time, there will be a big promotion, after that, will fall into a long period of confusion, may be a long time no progress, and then, in some conditions triggered, there will be a big upgrade, learning process, to undergo a number of quantitative changes to the accumulation of qualitative changes, To finally get a certain grade, moreover, the number of quantitative and qualitative change more than 3 times, should be more, after each qualitative change, you will feel that you understand a lot, and even have any understanding of the feeling, slowly, and will feel that they seem to understand nothing, until the next qualitative change.
4, don't blindly follow
Why are you talking about this? The main is to see a lot of people's learning trajectory, blindly follow other people's learning methods, or growth trajectory, perhaps, you can quickly and others as successful, even, you can surpass him, but, most, or you are living in his shadow, It seems to be a bit serious, in fact, some people are just like that.
For example, the previous study of Oracle internal, so as to prove that they are very strong, then, many people are research, have their own dump, look at the dump content is proud, and no matter what the basis of their own. But there are those who have been focusing on practice from the beginning, there are few Oracle research, the final result, can not say which side is good, both sides may be successful, but, many times, each way there are always some people, walk behind others, do not think of new methods, but always complaining, When will I be able to overtake him?
There was a colleague's reason for leaving his job because he felt that he could not surpass me, and recently, a colleague joked that he wanted to learn something else, and when it was time to learn Oracle, it was too difficult to surpass us. In fact, the main problem here is not to see the development, because he is walking me, or someone else's old way, and from this road again may be too difficult to cross, but, in fact, the big direction after the small direction is still a lot of. Typical I think there is a dcba, in fact, when I met him later, at that time also can not see him very good, but chao_ping after talking with him, think he is very good, now, he developed a lot of tools, are worthy of our learning.
