INTRODUCTION

Oracle Database (known as Oracle RDBMS or simply Oracle) is a database management system with various models produced and marketed by Oracle Corporation. It is a database that is commonly used to perform online transaction processing (OLTP), data warehousing (DW), and mixed database workloads (OLTP and DW). The latest generation, Oracle Database 19c, is available locally, in the cloud or in a hybrid cloud environment. 19c can also be provided on the site on Oracle Engineered Systems (e.g., Exadata), in the Oracle cloud (public), or in the customer’s (private) cloud. At Openworld 2017 in San Francisco, Larry Ellison, Executive President and Chief Technical Officer announced the next generation of databases, Oracle Autonomous Database. Oracle is the largest database on the market, mandatory for companies that need to store, organize, and dispose of all information.

For many users, Oracle software is easier to use.

Relational Database Management System (RDBMS)

The relational model is the basis of a relational database management system (RDBMS). Basically, an RDBMS moves the data into a database, stores it, and retrieves it so that applications can modify it. An RDBMS distinguishes the following types of operations: In this case, an application specifies the requested content.

For example, an application requires an employee name or adds an employee record to a table.

In this case, RDBMS determines how to proceed and perform the operation.

For example, after an application has queried a table, the database can use an index to find the requested rows, read the data in memory, and perform many other RDBMS archives and retrieves data so that physical operations are transparent for database applications.

An RDBMS that implements object-oriented functions such as user-defined types, inheritance, and polymorphism is called an object-relational database management system (ORDBMS).
