In computing, the Oracle Call Interface (OCI) consists of a set of C-language software APIs which provide an interface to the Oracle database. OCI offers a procedural API for not only performing certain database administration tasks (such as system startup and shutdown), but also for using PL/SQL or SQL to query, access, and manipulate data.
Such relational models provide declarative methods for specifying data and queries. In other words, users directly state what information the database contains and what information they want from it, and let the database system take care of describing data structures for storing the data and retrieval procedures for answering queries.
Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces.
Oracle Database is available by several service providers on-premises, on-cloud, or as a hybrid cloud installation. It may be run on third party servers as well as on Oracle hardware (Exadata on-premises, on Oracle Cloud or at Cloud at Customer). [5] Oracle Database uses SQL for database updating and retrieval.

Oracle Linux is deployed on more than 42,000 servers by Oracle Global IT; the SaaS Oracle On Demand service, Oracle University, and Oracle's technology demo systems also run Oracle Linux. [ 5 ] Software developers at Oracle develop Oracle Database , Fusion Middleware , E-Business Suite and other components of Oracle Applications on Oracle Linux.
A physical data model (or database design) is a representation of a data design as implemented, or intended to be implemented, in a database management system. In the lifecycle of a project it typically derives from a logical data model , though it may be reverse-engineered from a given database implementation.
An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object ...
