Informix - Informix The term Informix refers to a relational database, and for almost 20 years also referred to the company which developed it. The Informix DBMS developed from the pioneering Ingres system that also led to Sybase and SQL Server. For a time in the 1990s Informix was the second most popular database system, after Oracle. Success did not last very long, however, and by 2000 a series of management blunders had all but destroyed the company. In 2001 IBM purchased Informix in order to gain access to its existing market share and customer base. Long-term plans to merge Informix technology with DB2 have emerged, since the Informix Arrowhead project has now become the DB2 Arrowhead. IBM has also undertaken to support older versions.

Informix-4GL - Informix-4GL Informix 4GL is a fourth-generation language developed by Informix around 1986. It includes embeded SQL, a report writer language, a form language mixed with imperative capabilities (like functions, if and while statements, etc). This language is still widely used to develop business aplications, and is now property of IBM. In the meanwhile several companies have built clone versions of 4GL, some with extended functionalities, like GUI(s) and IDE(s), namely 4JS and Querix. A company in the Latin America built a convertor to java. There is an free GPL version called Aubit 4GL..
Ingres - from other projects at Berkeley, was available at minimal cost under a version of the BSD license. By the mid-1980s Ingres had spawned a number of commercial database applications, including Sybase, SQL Server, NonStop SQL, Informix and a number of others. A follow-on project started in the mid-1980s as Postgres, leading to the development of PostgreSQL, Illustra, and later versions of Informix. By any measure, Ingres is one of the most influential modern computer research projects. History Ingres In 1973 when the System R project was getting started at IBM, the research team released a series of papers describing the system they were building. Two scientists at Berkeley, Michael Stonebraker and Eugene Wong, became interested in concept after reading the papers, and decided to start a relational database research project of.
Fourth-generation programming language - were born report-generator languages, which were fed a description of the data format and the report to generate and turned that into a program which actually contained the commands to read and process the data and place the results on the page. Some other successful 4th-generation languages are: database query languages, e.g. SQL, Informix-4GL, Focus, Metafont, PostScript, RPG-II, S, IDL-PV/WAVE, Gauss, Mathematica and data-stream languages such as AVS, APE, Iris Explorer.

Database management system - particular record. When information was being collected about a user, information stored in the optional (or related) tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as their key. This "re-linking" of related data back into a single collection is something that traditional computer languages are not designed for. Just as the navigational approach would require programs to loop in order to collect records, the relational approach would require loops to collect information about any one record. Codd's solution to this problem was to create a new language dedicated to just this problem, a suggestion that would later develop into the almost-universal SQL today. Using a.
DB2 - into DB2, Oracle seized the opportunity to trumpet that it too used SQL. Currently, there is a dogfight going on between DB2 and Oracle for the number 1 position in the market. Historically, it is interesting to note that when Informix acquired Illustra and introduced make their database engine a object-relational database by introducing their Universal Server, both Oracle and IBM followed suit by changing their database engines to be capable of object-relational extensions. Technically, DB2 can be considered to be an object-relational database. DB2 started out on the mainframe but soon migrated down through UNIX and Windows servers to PDAs. DB2 is also the designation of an Aston Martin sportscar dating from the early 1960s..
Computing blade - also refer to them as 1RU (1 rack unit) servers, as they occupy a single slot in an electrical equipment rack. Hardware vendors such as Sun Microsystems and Hewlett-Packard and software vendors like Informix (with its DataBlades) have attempted to popularise the blade approach. Compare the concept of a RAID device as a sort of storage blade. For other uses of the word blade see blade (disambiguation).

Maddox Source: Official FAQ Maddox claims to receive lots of email and work for a telemarketing company writing programs in Informix 4GL/SQL, Perl (CGI), C, C++, Unix shell (Korn shell, Bourne shell, Bash), Sed/Awk, Java and PHP. Maddox describes himself as a 25 year-old mathematics student at the University of Utah. He says he works 40-60 hours per week. His website is made using Vi and Unix. He claims to have had 79 marriage proposals from women and 4 from men. Part of his "shtick" is to write sentences such as, "I'm The Center of the Universe," "I'm better than everyone," "I love me," "I AM KING," etc. (see [1])..

Sybase - to refer to the company itself. Sybase was a developer of the pioneering Ingres system that also led to Informix and NonStop SQL, as well as the majority of other SQL systems currently in use. Sybase was traditionally the #2 database system behind Oracle, though it suffered a major downturn in fortune in the later half of the 1990s when Informix started outselling it by a wide margin. Today Informix is no longer there (having been bought by IBM). As judged by revenue, IBM has taken the lead in the overall database market with Oracle a close second. The #3 position is occupied by Sybase's own offspring, Microsoft SQL Server. Today Sybase is well behind its major competitors, with less than 10% market share. Sybase has its corporate headquarters in Dublin,.
QUEL - effort at University of California, Berkeley, and was used for a short time in most products based on the freely-available Ingres source code, most notably Informix. As Oracle and DB2 started taking over the market in the early 1980s, most companies supporting QUEL moved to SQL instead. QUEL was generally more "normalized" than SQL. Whereas every major SQL command has a format that is at least somewhat different than the others, in QUEL a single syntax was used for all commands. For instance, here is a sample of simple session that creates a table, inserts a row into it, and then retrieves and modifies the data inside it. create student(name = c10, age = i4, sex = c1, state = c2) append to student(name = "philip", age = 17, sex =.
PHP programming language - a fundamentally internet-aware system and as such there are modules built in for accessing FTP servers, all manners of database servers, LDAP servers and much more. In addition to this, many familiar C functions such as printf() and strstr() are all available in the core namespace. PHP has a wide variety of extensions such as support for the Windows API, process management on Linux, cURL support, ZIP, gzip and bzip2 support. Some of the more unique features are PDF generation, Shockwave Flash generation (on the fly), integration with IRC and much more besides.

Object-relational database - address book type application an additional table would be added to the ones above to hold zero or more addresses for each user. Using a traditional RDBMS, collecting information for both the user and their address requires a "join": SELECT InitCap(C.Surname) ', ' InitCap(C.FirstName), A.city FROM Customers C, Addresses A WHERE A.Cust_Id=C.Id -- the join AND C.city="New York" The same query in an O-R system is much simpler: SELECT Formal( C.Name ) FROM Customers C WHERE C.address.city="New York" -- the linkage is 'understood' by the ORDB Many of the concepts in ORDBMS's were pioneered in the Postgres database, which eventually led to the open source PostgreSQL which is available today and gaining mind share. The first of the major database vendors to add O-R support to their products was Informix, which.
Michael Stonebraker - the exiting relational database market today. He is also the founder of Ingres and Illustra, and was previously the CTO of Informix. He is also an editor for the book Readings in Database Systems. Michael Stonebraker is currently teaching at MIT.

By the mid-1970s they had produced, using a rotating team of student programmers, a usable system known as Ingres. At the time Ingres was considered "low end" compared to IBM's similar effort, System R, as it ran on Unix-based DEC machines as opposed to the "big iron" IBM mainframes. However.
