| Oracle Database |
Oracle database is a relational database management system (DBMS) from Oracle, which runs on more than 80 platforms. The Oracle database, the current version of which is Oracle11i, is Oracle's flagship product. It was introduced in the late 1970s and was the first database product to run on a variety of platforms from micro to mainframe computers. |
| ORB: Object Request Broker |
An object request broker (ORB), a term in distributed computing, is a piece of middleware software that allows programmers to make program calls from one computer to another, via a network. ORBs handle the transformation of in-process data structures to the byte sequence which is transmitted over the network (of course, also the reverse transformation). This is called marshalling or serialization. ORBs often expose many more features, such as distributed transactions, directory services or real-time scheduling. In the object oriented languages, the ORB is an object, having methods to connect the objects being served. After such an object is connected to the ORB, the methods of that object become accessible for remote invocations. ORB must also have some means to obtain the network address of the object that has now become remote. The typical ORB also has many other methods. |
| ORD: Object-Relational Database |
An object-relational database (ORD) is a relational database that allows developers to integrate the database with their own custom data types and methods. The term object-relational database is sometimes used to describe external software products running over traditional DBMSs to provide similar features; these systems are more correctly referred to as object-relational mapping systems. |
| ORDBMS: Object-Relational Database Management Syst |
Object-relational database management system (ORDBMS) is a relational database management system that allows developers to integrate the database with their own custom data types and methods. Whereas RDBMS or SQL-DBMS products focused on the efficient management of data drawn from a limited set of data types (defined by the relevant language standards), an object-relational DBMS allows software developers to integrate their own types and the methods that apply to them into the DBMS. The goal of ORDBMS technology is to allow developers to raise the level of abstraction at which they view the problem domain. |
| OS/2: Operating System/2 |
Operating System/2 (OS/2) is an operating system created by Microsoft and IBM, later developed by IBM exclusively. OS/2 is no longer marketed by IBM, and support for OS/2 is to be discontinued on December 31, 2006. |
| OS: Operating System |
Operating system (OS) is a software program that manages the hardware and software resources of a computer. The OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files. The OS may be split into a kernel which is always present and various system programs which use facilities provided by the kernel to perform higher-level house-keeping tasks, often acting as servers in a client-server relationship. |
| OSF: Open Software Foundation |
Open Software Foundation (OSF) is an organization to create an open standard for an implementation of the Unix operating system. OSF's standard Unix implementation was known as OSF/1 and was first released in 1990, which is not widely deployed. Other well-known standards developed by OSF include Motif and the Common Desktop Environment, respectively a widget toolkit and desktop environment for the X Window System. In 1996, OSF merged with the X/Open Company to become The Open Group. |
| OSI: Open Source Initiative |
The Open Source Initiative (OSI) is an organization dedicated to promoting open-source software. Open Source Initiative was founded in February 1998 by Bruce Perens and Eric S. Raymond when Netscape Communications Corporation, published the source code for its flagship Netscape Communicator product as free software, due to lowering profit margins and competition with Microsoft's Internet Explorer software. |
| OSS: Open Sound System |
The Open Sound System (OSS) is a portable sound interface available in 11 different Unix systems. In the case of the Linux kernel, OSS was the only supported sound system used up to the 2.4.x series. Starting with version 2.5, the Advanced Linux Sound Architecture (ALSA) was introduced, and the OSS interface became deprecated by Linux' authors. ALSA contains an optional OSS emulation mode that transparently appears to programs as if it were OSS. |
| OSS: Open-Source Software |
Open-source software(OSS) is a type of computer software whose source code is available under a copyright license that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form. Benefits of OSS are that developers can customize programs, and these innovations, in turn, are shared within the programming community so that everyone learns from each other. Linux is one popular example of OSS. |
