In today's society, the certification of IT industry can add a lot to your resume. Oracle certifications are among the most popular in many IT industry certifications. The Oracle Certification system includes the following three certifications: OCA (Oracle Certified associate,oracle Certified Assistant), OCP (Oracle Certified professional,oracle certified Specialist), and OCM ( Oracle Certified Master,oracle Certified Master). Among them, OCA certification is the basis for Oracle database administrators to take part in the OCP certification exam. Two exams are required to qualify for OCA: One is a traditional form of examination, the book is a book to help readers prepare for this form of examination, and the other is to take an online exam.

As a translator of this book, I am honored to be able to bring this book into the country, so that more database administrators can read this highly practical Test Guide.
The most important experience in translating technical books is that the translation and reading of foreign technical books are very different. Reading foreign technical books and materials at work is a commonplace, but I realized after I started the translation work that I wanted to accurately express the original author's meaning, not to read it so easily. Not only that, this book condenses the unique insights of Oracle's certified Master Roopesh Ramklass, and I don't have the confidence to fully and accurately understand and express everything, even if I'm specialized in Oracle development. In order to ensure the accuracy and completeness of the translated content as much as possible, I have consulted with our product development team colleagues on many uncertain parts during the translation process. Here I would like to express my most sincere gratitude to all the colleagues of our team.
thanks to the editors of Tsinghua University Press, they have put forward a lot of valuable guidance during the translation of this book, helping to ensure the smooth translation and publication of the book. All chapters of this book are translated by Guo Junfeng and are also involved in translation activities such as Kong Xiangliang, Chen Yuehua, Du Shiming, Xiangxiaolei, Caohan, Tao, Wang Tong, Fang Jun, cheating, Caoxiaosong, Jiang Xiaodong, Chiupetiang, Hong Yan, Li Lianghui, Gao Juan, Cao Xiaozhen, Chen Li. Thank you for that!
due to the limited level of translators, the translation process may have inaccurate content, if the reader in the reading process found errors and omissions, hope to be able to forgive, and welcome criticism.
