Oracle

Oracle is one of the best softwares for database management. The Oracle Database is also known as Oracle RDBMS. But it is commonly known as Oracle as well. This is one of the softwares which is also known as a relational database management system. The Oracle Corporation has developed this software for the database computing.

The original software of Oracle has been developed by SDL in the year 1977. At that time SDL was also known as Software Development Laboratories also. Larry Ellison, Bob Miner and Ed Oates are the people behind the development of Oracle. The name “Oracle” had been derived from a project funded by CIA in which Larry Ellison had previously worked. There are various computing platforms which have used the software of Oracle Database. This software is of a lot of help to a large number of people as well as organizations.

Some of the default schemes of the Oracle Database include SYSTEM which means the additional core database structures and utilities as well as privileged account, SYS which means essential core database structures as well as utilities, BI, IX, HR, OE, PM, and SH which are the expanded sample of schemes containing further data as well as structures rather than the older SCOTT scheme and OUTLN which is used to store metadata for already available outlines for query optimizer plan stability.

Some of the Default tablespaces for the Oracle Database includes SYSAUX which is the data to supplement the SYSTEM scheme, TEMP which means temporary tablespace, SYSTEM which means essential core database structures and utilities, UNDOTBS1 which means undo tablespace and USERS which is the default users tablespace that is created by the Database Configuration Assistant but is also replaceable by the DBA.

The memory architecture of Oracle is also unique. There are various features related to this memory architecture. The features include System Global Area, Library Cache, Data Dictionary Cache and Program Global Area.

A very important part of the Oracle database is the Process architecture. This is is the group of processes which are running accordingly in the background as well as interacting to increase as well as monitor the database operations. Some of those processes include checkpoint process, database writer processes,archiver processes, dispatcher processes which is the multipleserver processes for the users, memory-monitor process, log-writer process, job-queue processes, memory-manager process, recoverer process, remote file-server process, system monitor process, shared server processes, logical standby coordinator process, media-recovery process, process-spawner,memory-monitor light process and process-monitor process.

There are 7 versions of the Oracle which has been released in the market. There are different numbering codes which has been used. These are Oracle7: 7.0.16 — 7.3.4, Oracle8 Database: 8.0.3 — 8.0.6, Oracle8i Database Release 1: 8.1.5.0 — 8.1.5.1, Oracle8i Database Release 2: 8.1.6.0 — 8.1.6.3, Oracle8i Database Release 3: 8.1.7.0 — 8.1.7.4, Oracle9i Database Release 1: 9.0.1.0 — 9.0.1.5Oracle9i Database Release 2: 9.2.0.1 — 9.2.0.8 , Oracle Database 10g Release 1: 10.1.0.2 — 10.1.0.5, Oracle Database 10g Release 2: 10.2.0.1 — 10.2.0.3 and Oracle Database 11g Release 1: 11.1.0.6.
