real time 1. [techspeak] adj. Describes an application which requires a program to respond to stimuli within some small upper limit of response time (typically milli- or microseconds). Process control at a chemical plant is the {canonical} example. Such applications often require special operating systems (because everything else must take a back seat to response time) and speed-tuned hardware. 2. adv. In jargon, refers to doing something while people are watching or waiting. "I asked her how to find the calling procedure's program counter on the stack and she came up with an algorithm in real time." | |

It does not actually deliver the data, but works alongside existing delivery channels such as {UDP}, {TCP}, or IP {multicast}. RTSP was developed by {RealNetworks}, {Netscape Communications}, and {Columbia University}, and is described in {RFC 2326}, April 1998. RTSP is an {IETF} proposed {standard}. {FAQ (http://www.real.com/devzone/library/fireprot/rtsp/faq.html)}. (1999-08-26) | |

relational algebra {semantics} used for modelling the data stored in {relational databases}, and defining queries on it. The main operations of the relational algebra are the {set} operations (such as {union}, {intersection}, and {cartesian product}), selection (keeping only some lines of a {table}) and the {projection} (keeping only some columns). The {relational data model} describes how the data is structured. {Codd's reduction algorithm} can convert from {relational calculus} to {relational algebra}. (1997-02-17) | |

relational data model by {E.F. Codd} in 1970, particularly well suited for business data management. In this model, data are organised in {tables}. The set of names of the columns is called the "schema" of the table. Here is an example table with the schema (account number, amount) and 3 lines. account number amount -------------- --------- 12343243546456 +30000.00 23149875245824 +2345.33 18479827492874 -123.25 The data can be manipulated using a {relational algebra}. {SQL} is a standard language for talking to a database built on the relational model (a "{relational database}").

relational database {database} based on the {relational model} developed by {E.F. Codd}. A relational database allows the definition of data structures, storage and retrieval operations and {integrity constraints}. In such a database the data and relations between them are organised in {tables}. A table is a collection of rows or {records} and each row in a table contains the same {fields}. Certain fields may be designated as {keys}, which means that searches for specific values of that field will use indexing to speed them up. Where fields in two different tables take values from the same set, a {join} operation can be performed to select related records in the two tables by matching values in those fields. Often, but not always, the fields will have the same name in both tables. For example, an "orders" table might contain (customer_id, product_code) pairs and a "products" table might contain (product_code, price) pairs so to calculate a given customer's bill you would sum the prices of all products ordered by that customer by joining on the product-code fields of the two tables. This can be extended to joining multiple tables on multiple fields. Because these relationships are only specified at retreival time, relational databases are classed as {dynamic database management system}. The first commercial RDBMS was the {Multics Relational Data Store}, first sold in 1978. {INGRES}, {Oracle}, {Sybase, Inc.}, {Microsoft Access}, and {Microsoft SQL Server} are well-known database products and companies. Others include {PostgreSQL}, {SQL/DS}, and {RDB}. ["Managing Data Bases, Four Critical Factors" Michael M. Gorman, QED Information Sciences, Inc.]. ["An Introduction To Database Systems" (6th ed) C. J. Date, Addison Wesley (an excellent source of detailed info)]. ["An End-User's Guide to Data Base" James Martin, Prentice Hall (excellent place to begin learning about DBMS)]. (2002-06-10) | |

relational language some property and some arguments. For example, if Tom has two brothers, Dick and Harry, a relational language will respond to the query "Who is Tom's brother?" with either Dick or Harry. Notice that unlike {functional language}s, relational languages do not require a unique output for each {predicate}/argument pair. {Prolog} is the best known relational language. (1995-03-31) | |
