Oracle is the first company to develop and deploy 100% internet-based enterprise software across the entire product line (database, business application software and application software development and decision support tools). The following is the Oracle certification administrator certification exam I compiled. I hope everyone will look carefully!
1. Oracle Bone Inscriptions is the second largest software company in the world after Microsoft.
Although Oracle Bone Inscriptions is large in scale, its fame is not as prominent as that of Microsoft and IBM. Many non-computer majors don't know what Oracle is. But if you are a student who wants to enter the IT industry after graduation, then you must know what Oracle is.
First of all, Oracle Bone Inscriptions is a software company. This California-based 1977 software company is the first company in the world to launch a relational data management system (RDBMS). Now, their RDBMS is widely used in various operating environments: Windows NT, minicomputers based on UNIX system, IBM mainframes and some special hardware operating system platforms. In fact, Oracle has become the largest RDBMS supplier and the most important information processing software supplier in the world. At present, Oracle Bone Inscriptions is the second largest software company in the world after Microsoft, with sales of 10 1 billion dollars in 2000. At present, there are more than 43,000 professional technicians in Oracle Bone Inscriptions and 2 1 1,000 in the United States. Interestingly, even in the United States, 40% of technicians (mainly programmers) in Oracle Bone Inscriptions are Indians, and China is the second largest, followed by Americans.
Then, Oracle Bone Inscriptions is a huge brand system. As mentioned above, Oracle not only introduced RDBMS first in the world, but actually occupied most of the market share. Since all the RDBMS of Oracle Company are named after Oracle, to some extent, Oracle has become synonymous with RDBMS. In recent years, Oracle has been actively expanding its business, and has successfully developed many horizontal and vertical products, such as Oracle server designed and produced by Oracle itself, commercial trading system for commercial customers (Oracle Exchange), Oracle data center and so on. At the same time, Oracle has also successfully developed many development tools for programmers, such as the famous Designer/2000 Computer Aided System Engineering (CASE) tool and Developer/2000 development kit. As "designers" and "developers", these tools have effectively helped programmers in their development work and improved the reputation of Oracle. In addition, Oracle has also developed a series of application software for different objects, collectively known as Oracle application software. These softwares have enabled Oracle Bone Inscriptions to be widely used in various fields, and at the same time brought huge financial resources to Oracle Bone Inscriptions. Common Oracle Bone Inscriptions software products are: Oracle Bone Inscriptions Financial. Software made in Oracle Bone Inscriptions. Oracle Bone Inscriptions human resources software. Oracle Bone Inscriptions Automatic Control Software (Oracle Bone Inscriptions Auto). Oracle Bone Inscriptions Commercial Trading System (Oracle Bone Inscriptions Stock Exchange)
And other applications. Together with OracleRDBMS, these softwares make Oracle a huge brand system, which permeates all fields of people's production and life.
Because Oracle has a variety of solutions in various industries for many years, including Oracle RDMBS server tools based on different customer environments and huge application software systems. Moreover, this huge system has been widely used in all walks of life to varying degrees and at different levels. Therefore, professional engineers who can master some aspects of this system skillfully and adapt to the continuous updating of this system must be urgently needed talents from all walks of life and have good employment prospects. In fact, Oracle Bone Inscriptions also realized this, which is the origin of Oracle Bone Inscriptions certified expert OCP (Oracle certified professional).
Second, the introduction of Oracle certification types
-Oracle Bone Inscriptions certification expert OCP is an international examination certification center authorized by Oracle Bone Inscriptions Company to certify candidates' qualifications. Candidates who take several courses (usually 3-5 courses) according to the examination standards can obtain OCP expert certification after passing all the examinations.
At present, OCP certification examination is divided into:
Database administrator: DBA for short. The database administrator is responsible for the daily management, backup and recovery after the database crash.
Database Operator: Database Operator Certification Examination, referred to as DBO. Database operators are mainly based on Oracle 8 database management of Windows NT, and can skillfully apply OEM and other tools to complete database operation and daily management.
Database developer: Database developer certification exam, referred to as DEV. Database developers should be able to skillfully use the tools of Developer/2000, establish various form applications, and establish various standard and customized reports.
Java developer: Java developer exam.
Application consultant: Oracle Bone Inscriptions product application consultant.
Among them, Oracle DBA is the most popular, but it is also the most difficult to authenticate. On the official website of Oracle, there are the following instructions for DBA:
Oracle DBA experts can meet the needs of today's increasingly complex system environment. The best database administrators work behind the scenes. They carefully maintain the system so that it can run smoothly every day and prevent unexpected disasters, such as database crash or hours of downtime. This arduous task requires a broad and in-depth understanding of the structure and operation mode of Oracle database and rich practical experience. The best DBA can find a balance between getting the best running state and preventing his own company from stopping running. The Oracle DBA certification exam is to provide a certification that proves that this person can be qualified for the position of Oracle DBA. This certification exam has designed five independent exams, so that you can get expert certification with good knowledge.
Third, how to test?

Fourth, how to prepare for the exam?
1, the official preparation route recommended by Oracle Bone Inscriptions Company.
Generally speaking, Oracle Bone Inscriptions has a lot of examination contents and detailed examination questions, which requires strong hands-on ability.

The above official introduction of Oracle Bone Inscriptions only gives you a general elementary education about preparing for the exam. In fact, as we said earlier, as a huge database system, it is not easy to master Oracle Bone Inscriptions from any angle (let alone completely master it-I even doubt whether anyone really fully masters it). Only if you have enough determination and patience, take Oracle as your career path and devote yourself to the research of database technology, can you really understand the essence of this complex system. The following discussion will help you have a preliminary understanding of Oracle.
2. Basic knowledge of 2.Oracle database technology
(1)Oracle database covers all aspects of database technology.
Although relational database is not difficult in principle, it won't take much effort for people who have some database knowledge to master these principles, and general relational database software, such as SQL Server, is not complicated to use, but Oracle is definitely different. As the most successful relational database software in history, Oracle has rich implementation methods and management and maintenance methods, involving many detailed technologies. It's hard to understand from either side alone. If you really want to master it, you can't do it without two or three years. Oracle's technical documentation alone is enough to make you feel overwhelmed! Specifically, Oracle technology includes the following main aspects: Oracle system structure and principle, Oracle database installation and configuration, Oracle database management, Oracle data backup and recovery technology, Oracle performance adjustment, Oracle new product features (Java support, application server, spatio-temporal series, text service, etc. ), Oracle parallel server technology, Oracle data warehouse technology, Oracle object type and object relationship model, etc.
It is no exaggeration to say that it is a big problem to take out any of the above parts alone!
(2)Oracle technology has developed rapidly, and the technology has great relevance.
Although Oracle is only a database system, in practical application, you can't just face the database itself. For example, if you are doing the network management of Oracle database, you will inevitably encounter the problem of how to be compatible with network communication and firewall technology. Similarly, if you are doing other work, there must be various technical-related problems to be solved. What's more, these technologies (including Oracle Bone Inscriptions itself) are developing very fast, and it is very difficult to keep up with their development.
Fortunately, however, we don't need to know all aspects of Oracle Bone Inscriptions at the same time. Oracle provides many application directions. We can choose one of them according to our own preferences and concentrate our time and energy, so it is not difficult to achieve something in this direction. As Oracle Bone Inscriptions is now the world's leading database supplier and the second largest software company, Oracle Bone Inscriptions's database technology has been widely used in various fields, so the demand for Oracle Bone Inscriptions talents in the market is considerable. You can't find a job without OCP certification. You can apply what you have learned in your work in the future, and then study Oracle database and related technologies hard.
