A server is a computer that hosts software which users can access through their client computers. The server and its clients are connected through a network, which allows users on client machines to use the services provided by the server.
Relational Database
A relational database organizes data into normalized tables, which are individual tables that don't contain data redundancies and that have a primary key, which is a unique identifier for each row of data in the table. A relational database can combine data from multiple tables by joining tables that share the same primary key through a query language, such as SQL.
The Oracle Database Client
Users can access the Oracle database through their client computers and submit requests for information, which the Oracle server will respond to. At a bank that uses Oracle database software, a teller could submit a query from her computer, the Oracle database client, to the Oracle server to retrieve a customer's account information.
