An object-oriented and Web-enabled program development methodology. RUP is like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development. RUP and similar products.

RavenDB is a transactional, open-source Document Database written in .NET, that offers a flexible data model designed to address requirements coming from real-world systems. RavenDB allows you to build high-performance, low-latency applications quickly and efficiently. Data in RavenDB is stored schema-less as JSON documents, and can be queried efficiently using Linq queries from your .NET code or using RESTful API using other tools. Internally, RavenDB makes use of indexes which are automatically created based on your usage, or created explicitly by the consumer. RavenDB is built for web-scale, and offers replication and sharding support out-of-the-box.

A virus that opens a backdoor on a computer running Windows, creates a copy of itself in the Windows system directory and creates a log file containing the port number on which its back door component listens. 

Data that has not been processed for use. A distinction between 'data' and 'information' is that information is the end product of data processing. Raw data that has undergone processing is sometimes referred to as 'cooked data'.

An option in the VMware server virtualization environment that enables a storage logical unit number (LUN) to be directly connected to a virtual machine (VM) from the storage area network (SAN).

Abbreviated as RT, Retweet is used on the Twitter Web site, to share content that has been posted by another user with your followers. Retweeting causes a ripple effect, helping more people hear about an interesting Tweets.

React, sometimes styled React.js or ReactJS, is an open-source JavaScript library for creating user interfaces that aims to address challenges encountered in developing single-page applications. React is simple, declarative, composable and is started with an intention to help developers build large applications that use data that changes over time. React only handles the user interface in an app; it is considered to only be the view in the model–view–controller (MVC) software pattern, and can be used in conjunction with other Javascript libraries or larger MVC frameworks such as AngularJS. It can also be used with React-based add-ons that take care of the non-UI parts of building a web application.

React Native is an open-source solution for developing native iOS and Andriod applications using JavaScript and React. It is developed by Facebook to enable you to build world-class application experiences on native platforms. The focus of React Native is on developer efficiency across all the platforms you care about — learn once, write anywhere.

The Reactive Extensions (Rx) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators. In traditional desktop or web-based applications, developers deal with asynchronous and even based programming from time to time. With the help of Rx, the observable interface notifies the subscribed observer interface whenever an event occurs. Since observable sequences are data streams, one can query those using standard LINQ query operators and filter, aggregate, compose and perform time based operations on multiple events.

A component of the Oracle 9i database product that allows a database to be installed across multiple servers. RAC's shared disk method of clustering databases increases scalability, lowers costs, and improves availability.

Real estate is Property consisting of land and the buildings on it along with its natural resources.

An application-level protocol for the transfer of real-time media data. The protocol is used to establish and control media sessions between end points by serving as a network-remote-control for time-synchronized streams of continuous media.

Real-time analytics is a process of delivering information as they happen. Real-time analytics also called as Real-time intelligence consists of dynamic analysis and reporting, based on data entered into a system less than one minute before the actual time of use.

An application program that functions within a time frame that the user senses as immediate or current. The latency must be less than a defined value, usually measured in seconds.
