A database management system is a collection of programs written to manage a database. That is, it acts as a interface between user and database.
Relational Data Model was developed by Dr. Logical Structures are tablespaces, Schema objects, extents and segments. A database is divided into logical storage units called tablespaces, which group related logical structures together.
Each Tablespace in turn consists of one are more datafiles. In relational database system all the information is stored in form of tables.
A table consists of rows and columns All the tables and other objects in Oracle are stored in tablespace logically, but physically they are stored in the datafiles associated with the tablespace. Every Oracle database has a set of two or more redo log files.
The set of redo log files for a database is collectively known as the database's redo log. A redo log is made up of redo entries also called redo records. The primary function of the redo log is to record all changes made to data. If a failure prevents modified data from being permanently written to the datafiles, the changes can be obtained from the redo log so work is never lost.
Every Oracle database has a control file. A control file contains the database name and locations of all datafiles and redo log files.
Every Oracle database also has a Parameter File.Databases for Developers: Foundations This FREE part boot camp will help you get started with Oracle Database and SQL.
