Oracle Database is the most popular relational database management system (RDBMS) in the world. It is used to store data, retrieve data and manage data in many different applications. It supports a wide variety of programming languages, including Java, C++, Perl, Python and Microsoft SQL Server.
Oracle Database can be installed on a single computer or across multiple computers that are connected by a network. It is available in three editions: Standard Edition, Enterprise Edition and Enterprise Edition One.
The Standard Edition provides basic database functions for small and medium-sized businesses. The Enterprise Edition provides additional features for larger companies that need to handle more complex tasks such as data warehousing and business intelligence (BI) analysis. The Enterprise Edition One adds more computing power so that you can run more complex queries at one time without waiting for them to complete.
Sample Oracle Database For Practice
Oracle by Example: 19c is a large Oracle database sample database. The latest version of the database contains over 100 tables, over 1,000 views and 2,000 procedures/functions. It is also available as a free download.
Oracle Sample Schemas
The following are some of the sample schemas available from Oracle:
Oracle Database 11g Sample Schemas: This is a set of sample schemas that can be used as templates for applications. These schemas are available in two formats – SQL script and XML file. The second format makes it easy to import these into other databases or create schema dumps for backup purposes.
The Oracle Database by Example 19c is a free sample database that you can download and import into the SQL Developer tool. This article explains how to import the database into SQL Developer and use it as the basis for your own projects.
Oracle Database by Example (DBX) is a sample database that provides examples of common usage scenarios in Oracle Database. The DBX contains a set of schemas with tables, views, and procedures, which are relevant to different application domains: banking, sales, HRM, travel and so on. The main purpose of DBX is to be used as a learning tool for new users who want to learn more about Oracle Database from examples rather than just reading documentation.
Oracle Sample Database:
The Oracle database sample database is a set of database schemas, stored procedures and scripts that demonstrate the features of the Oracle Database. The sample database is available for download from the Oracle Technology Network (OTN) website. It is provided as a compressed file to simplify downloading and installation.

Oracle Database for Practice
Oracle Database for Practice is a free, full-featured, and complete Oracle Database that can be installed on your laptop or desktop.
The download includes:
Oracle Database 19c (12.2) with the same functionality as Enterprise Edition but with a reduced feature set for smaller deployments. The database is pre-configured to run on the Oracle Cloud Infrastructure (OCI).
Oracle Database Migration Assistant (DMA), which helps you migrate from an existing database to Oracle Database 19c.
Oracle Database is a relational database management system developed by Oracle Corporation. The database is a multi-user, multiprocessing system that features an advanced query language, static SQL, and a flexible schema structure.
The Oracle Database provides high availability and scalability through features such as Data Guard, RAC and Grid Infrastructure. The database is available on multiple platforms, including Windows, Unix/Linux and Solaris operating systems.
The Oracle Database is often used as the backend for other products of Oracle Corporation such as Hyperion Financial Management Suite and PeopleSoft Enterprise.
The following schema files are included:
* A large sample database, called “Oracle_sample.DBF”. This is a 5GB oracle database with tables containing millions of rows in each table. You can use this database to experiment with SQL Developer and to learn about SQL Developer features and functions.
* Several smaller sample databases that you can use to learn about specific features. These include:
** A schema file for each of the introductory chapters in the book, which you can import into SQL Developer as described below. These schemas contain a variety of data types, functions and procedures that you can explore. Each chapter contains one or more schema files that correspond exactly with the examples in that chapter.
** The complete set of schemas from Chapter 2 through Chapter 19C, including all the examples in those chapters.
You can download one of the sample databases from the Oracle website.
There are many databases available.
Here is a list of them:

This is a guide for importing sample database in Oracle SQL Developer.
Create a Local Database:
Go to File > New > Database. Click Next. Click Next on the Database Properties window. Click Finish on the Create Local Database window. Your new local database will be displayed in SQL Developer’s Navigator tree view.
Import Sample Schema:
Go to File > New > Import Sample Schemas. Select the schema you want to import and click Next. You can choose whether or not to use the existing tablespaces or create new ones when prompted (this depends on whether you have existing tablespaces or not). Click Finish on the Import window when done.
