An object database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. Object–relational databases are a hybrid of both approaches.
IBM Informix is a product family within IBM's Information Management division that is centered on several relational database management system (RDBMS) offerings. The Informix products were originally developed by Informix Corporation, whose Informix Software subsidiary was acquired by IBM in 2001. In April 2017, IBM delegated active development and support to HCL Technologies for 15 years while keeping part of the marketing responsibilities.
Db2 is a family of data management products, including database servers, developed by IBM. They initially supported the relational model, but were extended to support object–relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB/2, then DB2 until 2017 and finally changed to its present form.
A software release life cycle is the sum of the stages of development and maturity for a piece of computer software. Cycles range from its initial development to its eventual release, and include updated versions of the released version to help improve software or fix software bugs still present in the software.
IBM i is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008. It is an evolution of the System/38 CPF operating system, with compatibility layers for System/36 SSP and AIX applications. It inherits a number of distinctive features from the System/38 platform, including the Machine Interface, the implementation of object-based addressing on top of a single-level store, and the tight integration of a relational database into the operating system.
In computing, the Perl DBI offers a standardized way for programmers using the Perl programming language to embed database communication within their programs. The latest DBI module for Perl from CPAN can run on a range of operating systems.
World Community Grid (WCG) is an effort to create the world's largest public computing grid to tackle scientific research projects that benefit humanity. Launched on November 16, 2004, it was co-ordinated by IBM with client software currently available for Windows, Linux, macOS, and Android operating systems. In September 2021, it was announced that IBM transferred ownership to the Krembil Research Institute.
The following tables compare general and technical information for a number of relational database management systems. Please see the individual products' articles for further information. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.
Free and open-source software (FOSS) is software that is both free software and open-source software where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.
WebSphere Application Server Community Edition (WASCE) was a free-of-charge, certified Java EE 6 application server for building and managing Java applications. Until September 30, 2016, it was IBM's supported distribution of Apache Geronimo that usee Tomcat for servlet container and Axis 2 for web services. Another difference from Apache Geronimo is that WASCE came with Db2 and Informix database drivers, better XML parser libraries and contained the latest patches from unreleased upstream versions. Over 30 WASCE developers were committers in the Apache Geronimo project.
The DUAL table is a special one-row, one-column table present by default in Oracle and other database installations. In Oracle, the table has a single VARCHAR2(1) column called DUMMY that has a value of 'X'. It is suitable for use in selecting a pseudo column such as SYSDATE or USER.
IBM Data magazine is a U.S.-based custom, online magazine published by TDA Group for IBM Corp. With a worldwide readership of more than 100,000, the magazine provides how-to information about Db2, Informix, UniVerse, and UniData, along with coverage of related tools, software, and solutions.
The International Informix Users Group (IIUG) is a non-profit organization whose goals are to provide support and education for users of Informix products and technology.
A hierarchical query is a type of SQL query that handles hierarchical model data. They are special cases of more general recursive fixpoint queries, which compute transitive closures.
Fear, uncertainty, and doubt is a propaganda tactic used in sales, marketing, public relations, politics, polling and cults. FUD is generally a strategy to influence perception by disseminating negative and dubious or false information and a manifestation of the appeal to fear.
