Oracle
Oracle is a relational database management system developed by Oracle Corporation. It has been the most widely used relational database management system in the world since the late 1990s.
The Oracle Database supports many of the SQL standard, including scalar subquery optimization and joins, but does not support all of the language features, such as recursive queries, foreign keys and outer joins.
It has an object-relational data model that uses extensible structures to store complex data types. The Oracle Database can manipulate and store data within these structures with any number of columns and rows, which allows for large amounts of information to be stored within a single table structure.
Oracle HR Schema Script
The Oracle HR schema script is a sample database that comes with the Oracle 11g software. The script is used to create an Oracle HR sample database. It contains all the objects, data and scripts for creating the HR schema. You can download the script from Oracle website or you can also download it from my blog in pdf format.
The Oracle HR schema contains all the tables, views and sequences required by an employee management system. It also contains many sample records to demonstrate how you can use this database to create your own application.
You can use this template to create your own application by modifying it as per your requirement.
In this post we are providing a sample database schema for Oracle HR. The schema is created using Oracle SQL Developer and then exported as a .sql file. The .sql file contains all the tables, views, synonyms, sequences etc.
The download will contain following files:
1- Oracle HR Schema Script with Data.sql – This is the complete schema script with all the data from the database (around 1MB). This can be imported in any other database and can be used as a reference to create your own schemas or modify existing ones.
