Classification database
For the current database we come into contact, I usually divide them into three types:
- Traditional database (RDBMS)
- NoSQL databases
- Exadata Version
For the traditional type of database, what we call relational database management system (RDBMS), is nothing more than add, delete, change, search, four more important operation,
it is to "search" operation after optimization, how quick check, check prospective, it is our most important point, especially for some DBA direction you want to go for a small partner, but also for optimizing and indexing lock concept, to do a more in-depth understanding!
NoSQL databases, as its name suggests, "NO"!
From the initial "Not SQL", to be finalized in "Not Only SQL", which is due to take large have found that if you really want to abandon the traditional type of database, in fact, is unrealistic, therefore, on the basis of this to finalize the current NoSQL, it is "Not Only SQL", not just the traditional database!
In the next period of time, I will talk with the top three database, slowly, all understand!
