Which type of database architecture does Oracle use?
Oracle is a fully scalable relational database architecture and is often used by global enterprises which manage and process data across wide and local area networks. The Oracle database has its own network component to allow communications across networks.
What is Oracle Database design?
Principles of Database Design for Oracle Parallel Server. Database Operations, Block Types, and Access Control. Global Cache Coherence Work and Block Classes. General Recommendations for Database Object Parameters. Logical And Physical Database Layout.
What are the components of Oracle architecture?
An Oracle instance consists of three main parts: System Global Area (SGA), Program Global Area (PGA), and background processes. The SGA is a shared memory structure allocated when the instance started up and released when it is shut down.
What is technical architecture in Oracle?
An Oracle Real Application Clusters (Oracle RAC) database architecture consists of multiple instances that run on separate server machines. All of them share the same database. The cluster of server machines appear as a single server on one end, and end users and applications on the other end.
Which of the following database architectures is most commonly used?
The most popular data model in use today is the relational data model. Well-known DBMSs like Oracle, MS SQL Server, DB2 and MySQL support this model. Other traditional models, such as hierarchical data models and network data models, are still used in industry mainly on mainframe platforms.
What are the different techniques used for database design?
There are two methods of database design: 1. Bottom Up or Design by Synthesis. 2. Top Down or Design by Analysis.
What is the Oracle architecture?
Oracle Database Architecture. An Oracle database is a collection of data treated as a unit. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data.
What type of database is Oracle?
RDBMS
Oracle Database is an RDBMS. An RDBMS that implements object-oriented features such as user-defined types, inheritance, and polymorphism is called an object-relational database management system (ORDBMS).
What is database architecture?
Database architecture focuses on the design, development, implementation and maintenance of computer programs that store and organize information for businesses, agencies and institutions. A database architect develops and implements software to meet the needs of users. The design of a DBMS depends on its architecture.
What is database architecture with example?
The architecture of DBMS depends on the computer system on which it runs. For example, in a client-server DBMS architecture, the database systems at server machine can run several requests made by client machine. We will understand this communication with the help of diagrams.
What are the components of the Oracle 11g architecture?
Oracle Database 11g Architecture Basically, there are two main components of Oracle database –– instance and database itself. An instance consists of some memory structures and the background processes, whereas a database refers to the disk resources. In this section, will cover the following topics related to the Oracle architecture:

What are the memory structures associated with Oracle?
The basic memory structures associated with Oracle Database include: System global area (SGA) The SGA is a group of shared memory structures, known as SGA components, that contain data and control information for one Oracle Database instance. The SGA is shared by all server and background processes.
What is Oracle and what is it used for?
Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Enterprise grid computing creates large pools of industry-standard, modular storage and servers.
