  The Dispatch - Serving the Lexington, NC - News
System R was a seminal project: it was the first implementation of Structured Query Language (SQL), which has since become the standard relational data query language.
It was also the first system to demonstrate that a relational database management system could provide good transaction processing performance.
Design decisions in System R, as well as some fundamental algorithm choices (such as the dynamic programming algorithm used in query optimization), influenced many later relational systems.

System R ist ein von IBM im San Jose Research Center (heute IBM Almaden Research Center) entwickeltes Datenbankmanagementsystem.
Es ist historisch von großer Bedeutung, da es das erste Relationale Datenbankmanagementsystem war und als erstes die SQL-Abfragesprache implementierte.
System R zeichnete sich bereits durch eine gute Transaktionsleistung aus und hatte einen fortgeschrittenen Anfrageoptimierer sowie B-Bäume als Indexverfahren.

 System R: An architectural overview
System R is an experimental data base management system that was designed to be unusually easy to use.
System R supports a high-level relational user language called SQL, which may be used by ad hoc users at terminals or by programmers as an imbedded data sublanguage in PL/I or COBOL.
Host language programs with imbedded SQL statements are compiled by System R, which replaces the SQL statements with calls to a machine-language access module.

 Hints for computer system design   (Site not responding. Last check: 2007-10-11)
Few systems are well enough understood to be properly tuned without such tools; it is normal for 80% of the time to be spent in 20% of the code, but a priori analysis or intuition usually can’t find the 20% with any certainty.
When the system is programmed in a language without type-checking, it is nearly out of the question to change any public interface because there is no way of tracking down its clients and checking for elementary incompatibilities, such as disagreements on the number of arguments or confusion between pointers and integers.
In most systems it is all right to schedule unfairly and give no service to some of the processes, or even to deadlock the entire system, as long as this event is detected automatically and doesn’t happen too often.

Debian is a free operating system (OS) for your computer.
An operating system is the set of basic programs and utilities that make your computer run.
Debian uses the Linux kernel (the core of an operating system), but most of the basic OS tools come from the GNU project; hence the name GNU/Linux.

 PHP: system - Manual
If you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends.
We were using system() to call a Cocoa command-line binary from PHP using Mac OS X. The Cocoa binary was simply not working -- no error message, no logging, nothing, it would just die within moments of launching from the system() function and we'd get no results.
I was trying to use the system command, and I couldnt get it to work, then it occured to me, send the stderr to a file to see what is really happening.

 Relational DBMS Implementation - OS vs. DBMS
Codd presents the relational model to solve this problem and system R is the first integrated database system based on system R. The significance of data independence and relational model are not rephrased here which have been introduced by another review on Codd's paper.
In this stage, the main purpose of system R is trying to demonstrate the usefulness of relational model by building it.
The task for this stage is to evaluate of system R by users and many function enhancement and improvements from users' experiences.

 ACM: Software System Award / System R - INGRES   (Site not responding. Last check: 2007-10-11)
The INGRES and System R systems demonstrated that a practical and efficient database management system (DBMS) could be implemented based on the relational data model.
These systems were full-function DBMS's that supported non-procedural query languages (QUEL and SQL), automatic query optimization, alternative storage structures, transactions, crash recovery, views, integrity, and protection.
They have revolutionized the database system industry by showing how data stored in a computer can be conveniently accessed by end users and while at the same time it can be used by production application programs.

 TickQuest Inc. NeoTicker(R) - Trading System Development & Automated Trading
When you write a trading system, your focus is on the most current bar, with past data available in read-only form, and future data completely blocked out.
If you expect to write non-trivial trading systems, or if you expect your trading systems to be reviewed by peers, at-the-point evaluation is a must have feature.
When testing with tick data, ticks are sent to a trading system and the trading system will react to the data on a tick-by-tick basis, identical to the situation when the trading system is running in real-life.

 Dovada Radio Immobilizer System Key (R.I.S.K) operation
When designing the car alarm Radio Immobilizer System Key (R.I.S.K.) it became necessary to build into the (R.I.S.K.) immobilizer several safeguards, which satisfy both the owner/driver of the motor vehicle and the effective police operation of the (R.I.S.K.) immobilizer in the emergency situation.
The (R.I.S.K.) car alarm radio immobilizer system key needed to be an effective control method for the pursuing police vehicle, and yet the normal lawful use of the motor vehicle had to have the ability to disable the (R.I.S.K.) radio immobilizer system key, to satisfy the privacy and independence of the owner driver.
The use of a (R.I.S.K.) car alarm immobilizer or similar car security system would greatly increase safety for the police and other road users, with obvious savings to insurance companies as it minimizes the risk of severe damage to the vehicles involved.
