Oracle Database and Licensing in modern times



Oracle Database

The information technology is the area that can help almost all the segments of the modern economy, and that is why there is no avenue left which does not depend on it now. One of the main parts of this technology is a language which is known as Oracle.

Oracle Database or Oracle RDBMS or simply Oracle is an Object-Oriented Relational Database Management System developed by Oracle Corporation. The name “Oracle” comes from the name (-codename) of a project funded by CIA that Lawrence Ellison had worked on. The database was originally developed in 1977 by the founder of Oracle Lawrence Ellison and his team. Now it is the most widely used database around the globe.

The Oracle database was developed so that it can run on every major platform like Linux, Windows, UNIX and Mac OS. The market although filled with various other databases is mostly occupied by the Oracle DB and SQL Server. The company offers various versions of the database depending on budget and requirements of different customers. Currently, the company is offering the following editions:

  • Enterprise Edition.
  • Standard Edition.
  • Express Edition.
  • Oracle Lite.

The Enterprise Edition from the brand comprises all the features of the database including high performance, security, and robustness. Standard Edition, on the other hand, consists only basic functionalities of the Oracle DB. Express Edition and Oracle Lite are the lightweight versions of the database and limited to Windows, Linux, and mobile phones respectively.


  1. Storage:

The data in the Oracle RDBMS is stored in the form of tablespaces (logically) and the form of files or “data files” (physically). The tablespace may consist of different types of memory segments like Index segment, data segment, etc. The segment contains extents which may further contain groups of data blocks. The data blocks are the smallest storage unit in the database.

  1. Partitioning:

This feature wasn’t initially present in the Oracle database but was added later in Oracle 8. The feature allows partitioning the tables on the basis of various sets of keys. The partitions can then be dropped and added separately to manage large data blocks.

  1. Monitoring:

The Oracle DB tracks its database storage with the help of SYSTEM tablespaces which contains data dictionary, clusters, and indexes. The data dictionary consists of tables which contain information about the user-objects of the database.


A license can be thought of as an agreement with the developer of a product that establishes “right to use” of the software by the customer.

Oracle Licensing can be easily done by contacting with Oracle directly or through an ISV (Independent Software Vendor) or any Oracle Partner. Oracle Database License is currently being offered under following metrics:

  • Unlimited License Agreements: This is a time-based license with unlimited use for certain Oracle technologies.
  • Processor Licensing: In this type of license the customer pays as per the processor it runs Oracle software on.

Other licenses include Standard Edition Per-socket licensing, Enterprise Edition Per-core licensing, Named User Plus Licensing, etc.
