Oracle basics-Introduction (first meeting) and oracle first meeting
I. Overall introduction:

Oracle databases and databases represent the basis of all Oracle database objects. Oracle is a large-scale relational database based on advanced Structured Query Language (SQL). In other words, it is used to manipulate a large set of regular data in a language that facilitates logical management. It is one of the most popular C/S architecture databases.

2. Feelings of first meeting:

My biggest feeling after reading Oracle is that this is not the basic knowledge of self-testing books on database design principles? So the longer the time, the more I feel like my knowledge network is circulating, and the wider the network is, the more I can feel the original intention of the sentence. "How can I build my knowledge into a knowledge network? Maybe you have been doing it without knowing it ......

The first time we met, we were not very familiar with Oracle. In fact, this kind of consciousness was formed unconsciously. It is a type of database. It is a large-scale relational database.

Iii. features:

  • Powerful Performance
  • Powerful Concept
Eg: brand new tablespace concept and more efficient locking mechanism
  • Enhanced SQL
Eg: hierarchical query, which is constantly enhanced
  • Good distributed management functions
You can easily coordinate multiple databases.
4. Good start: the definition of a new thing is actually a high appearance. self-testing and SQL learning have already laid a good foundation for you to continue!
