Oracle is hard to learn

Oracle may be the most widely used database in the world. At least in my projects, Oracle database applications account for half of the total. It can be said that in the past few decades, the front-end and business-layer technologies have changed, but the relational databases in the backend are still arrogant, which is enough to see the charm of relational databases. However, although Oracle is usually used in many cases, most of them are limited to SQL statements. It can be said that most of them are some general knowledge of SQL92, and not many of them know about the unique features of Oracle, it's just a part of it. In addition, although many stored procedures have been written in the project before, and many Oracle-specific things have been used in the stored procedures, I still feel that there is some distance from fully understanding Oracle.

I recently fell in love with databases. Of course, I have to study Oracle well and try to attack Oracle 10g. In Oracle10g, I have added many unique features, I think if we can make a good research, we usually provide a lot of functions in the project, but we don't know this function or how to use it, as a result, I did some repetitive work myself, resulting in repeated development, as well as bugs and performance problems.

I really want to go through my own learning and then take an OCA or even an OCP. But I still feel that the price of that certification is coming soon, after all, an Oracle10g OCP requires the first 20 thousand to be able to work out, but it is better to take a quick test, and it will not wait for these certificates to eat. I hope that I can gradually move myself closer to an Oracle DBA through a period of study.

I want to be an architect and a DBA. I don't know whether the two are in conflict, but I still want to learn both well. I am developing on both J2EE and. NET platforms, and it is not clear which one I want to master. At present, I am still a little more proficient in J2EE and tend to continue to deepen J2EE. The goal of. NET is to be able to deal with the general project design architecture.

I feel that the content of this blog is messy. I hope you will not be surprised.
