Overview of Primary Components
The Oracle architecture includes a number of primary components, which are discussed further in this lesson.
Oracle server: There are several files, processes, and memory structures in an Oracle server; however, not all of them are used when processing a SQL statement. Some are used to improve the performance of the database, to ensure that the database can be recovered in the event of a software or hardware error, or to perform other tasks necessary to maintain the database. The Oracle server consists of an Oracle instance and an Oracle database.
After completing this appendix, you should be able
to do the following:
Describe the Oracle Server architecture and its main components
List the structures involved in connecting a user to an Oracle instance
List the stages in processing:

Client-Server Application Connection
Oracle Net enables a network connection between a client and an Oracle database server. Oracle Net is a software component that resides on both the client and on the Oracle database server. It is layered on top of the network protocol.
When a connection is initiated from a client to the Oracle database server, data is passed down a stack on the client, over the network, and up a similar stack to the Oracle database server.
Expert Oracle Application Express Plugins is your “go to” book on the groundbreaking plugin architecture introduced in Oracle Application Express 4.0. Using the new APEX functionality, you can create well-packaged, documented, reusable components and reliably leverage your coding investments across many applications. Components you create can define new item and region types, specify validation processes, and present dynamic actions to client applications.

Oracle Real Application Clusters (RAC)1 is an option to the award-winning
Oracle Database Enterprise Edition. Oracle RAC is a cluster database with a shared
cache architecture that overcomes the limitations of traditional shared-nothing and
shared-disk approaches to provide highly scalable and available database solutions
for all your business applications. Oracle RAC is a key component of Oracle’s
enterprise grid architecture and cloud foundation.
The connection between the client and the database server is a key component of the
overall architecture of a computing system. The database connection is responsible
for supporting all communications between an application and the data it uses. Ora-
cle includes a number of features that establish and tune your database connections.
The following features relate to the way the Oracle database handles the connection
between the client and server machines in a database interaction.
