The radian is the standard unit of angular measure, used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it s; one radian is just under 57.3 degrees (expansion at ). The unit was formerly an SI supplementary unit, but this category was abolished in 1995 and the radian is now considered an SI derived unit.

Separately, the SI unit of solid angle measurement is the steradian.

The radian is represented by the symbol rad. An alternative symbol is , the superscript letter c (for "circular measure"), the letter r, or a superscript , but these symbols are infrequently used as it can be easily mistaken for a degree symbol () or a radius (r). So, for example, a value of 1.2 radians could be written as 1.2rad, 1.2r, 1.2, or 1.2, or 1.2.

Radian describes the plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc. One radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. More generally, the magnitude in radians of such a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, , where "" is the subtended angle in radians, "s" is arc length, and "r" is radius. Conversely, the length of the enclosed arc is equal to the radius multiplied by the magnitude of the angle in radians; that is, .

Rotten Tomatoes is an American review aggregation website for film and television. The company was launched in August 1998 by Senh Duong and since January 2010 has been owned by Flixster, which was, in turn, acquired in 2011 by Warner Bros. In February 2016, Rotten Tomatoes and its parent site Flixster were sold to Comcast's Fandango. Warner Bros. retained a minority stake in the merged entities, including Fandango. From 2007 to 2017, the website's editor-in-chief was Matt Atchity, who left in July 2017 to join "The Young Turks". The name "Rotten Tomatoes" derives from the practice of audiences throwing rotten tomatoes when disapproving of a poor stage performance.

From early 2008 to September 2010, Current Television aired the weekly "The Rotten Tomatoes Show", featuring hosts and material from the website. A shorter segment was incorporated into the weekly show, "InfoMania", which ended in 2011. In September 2013, the website introduced "TV Zone", a section for reviewing scripted TV shows.

Rotten Tomatoes was launched on August 12, 1998, as a spare-time project by Senh Duong. His goal in creating Rotten Tomatoes was "to create a site where people can get access to reviews from a variety of critics in the U.S." As a fan of Jackie Chan's, Duong was inspired to create the website after collecting all the reviews of Chan's movies as they were being published in the United States. The first movie whose reviews were featured on Rotten Tomatoes was "Your Friends & Neighbors" (1998). The website was an immediate success, receiving mentions by Netscape, Yahoo!, and "USA Today" within the first week of its launch; it attracted "6001000 daily unique visitors" as a result.

A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.[disputed discuss] Sometimes a DBMS is loosely referred to as a 'database'.

Formally, a "database" refers to a set of related data and the way it is organized. Access to these data is usually provided by a "database management system" (DBMS) consisting of an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data). The DBMS provides various functions that allow entry, storage and retrieval of large quantities of information and provides ways to manage how that information is organized.
