For example, I built two users in em new WWW and yyy, what is the relationship between them, and I in oracle configuration tool the new database what does it matter

CodePudding user response:

Can give different permissions to different users, to restrict to the operation of the database, the user can be an application, the database administrator, or a someone, just the access database is used to ensure the database security,

CodePudding user response:

Has nothing to do, it is independent of the user,

CodePudding user response:

Seems a just contact oracle's friend, it is recommended that you don't go to contact the em, or start from the basic concept of oracle, can also take part in some real training, premise is to study well, other not much said,

CodePudding user response:

Two users itself no difference, the difference is only reflected in the user's permissions

CodePudding user response:

reference 4 floor DongFangZiMo response:

two users itself no difference, only difference is the amount of users in the user's permissions on

reasonable

CodePudding user response:

Although an Oracle database server can be installed in multiple databases, but require a database of very large memory space, so generally a server only install a database, each database can have many users, different users have their own database objects (such as database tables), if a user access to other users of the database object, must be granted by the other user permissions, different users to create table, can only be the current user access, so in the Oracle development, different applications can use different user access,

CodePudding user response:

No link between the user and the powers of the distinction between them is different,

CodePudding user response:

Two residents inside a building, no contact

CodePudding user response:

Are two different users in the same database, two different users can access to database, non-interference in each other, the only difference may be granted permission to each other, also is the permission to access the database,
