Bought in Guangzhou, the frame is still, at least not as easy as Expert One-ORACLE, it is easy to break, it is easy to be bad, saying it back, not much like I am so picky.
Still talking about, overall belongs to the intermediate level: just started, not familiar with the oracle internal structure, it should be very tired, and it will feel very loose, don't learn something; master, in large parts, such as The use of EM, the introduction of utilities, will definitely feel very simple, not worth watching. In fact, it is also very practical, introduces the basic knowledge of EM, TKPROF and other tools, indexing, some foundations of the optimizer, etc., many scripts are also more practical, which can be said to be a combination of documents and experience. The tool introduction section also has a detailed illustration, simple and clear, the text is not dragged, but it does not feel boring. This is more detailed, and the threshold is relatively detailed, and it is a lot of theory. Since the chapter is reasonable, it is quite convenient to find it. No wonder there also a four-star evaluation on Amazon, just that price is high.
Amazon is mentioned because of the differences between the original and translation. It is also a regrettable book, translation and proofreading again insult readers. It should be said that the translation is good for Expert One-ONE Oracle. After all, many terms are more common easily understood, but there are still many low-level errors, and even cause the contradiction between the front and rear semantics. The proofreading is even more uncomfortable, actually in Tkprof, the output documents corresponding to the two parameters have been reversed. There are still many other words and hazards, and I have doubted the publication of the school, the responsible editor is It is not to pass the book, not to say technical cultivation, Chinese cultivation is always a bit. So if you have money, or buy the original version. (Individual recommendation If there is so much money, you may wish to buy Tom Kyte's two original books) Good error in overall mistakes, should not cause great troubles to readers.
Overall, this is a book, intermediate reading, comprehensive but not very deeply, and in-depth reference manual. The content is 80 points, the translation and the text are up to 60 points.
