Difference between oracle client and oracle server

[Devika Apk]

.) I have installed oracle client in my machine but i'm not able to export the data's from another user.
.) I created a new datacase using oracle assistants but i'm not able to create a user for that new database. Should i install oracle server? Will the server have the privileges?

You mean to say you installed only oracle client .

is there any server already .?

Is your system in a network with oracle server ?

In that case you need to configure your system accordingly to connect to the server.
