PostgreSQL also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance. PostgreSQL features transactions with atomicity, consistency, isolation, durability (ACID) properties, automatically updatable views, materialized views, triggers, foreign keys, and stored procedures. It is supported on all major operating systems, including Windows, Linux, macOS, FreeBSD, and OpenBSD, and handles a range of workloads from single machines to data warehouses, data lakes, or web services with many concurrent users.
PmWiki is a wiki-based content management system designed for a collaborative creation and maintenance of websites.
Second Life is a multiplayer virtual world that allows people to create an avatar for themselves and then interact with other users and user-created content within a multi-user online environment. Developed for personal computers and owned by the San Francisco-based firm Linden Lab, it launched on June 23, 2003 and saw rapid growth for some years; in 2013 it had approximately one million regular users. Growth eventually stabilized, and by the end of 2017, the active user count had fallen to "between 800,000 and 900,000". In many ways, Second Life is similar to massively multiplayer online role-playing video games; nevertheless, Linden Lab is emphatic that their creation is not a game: "There is no manufactured conflict, no set objective."
WorldCat is a union catalog that itemizes the collections of tens of thousands of institutions, in many countries, that are current or past members of the OCLC global cooperative. It is operated by OCLC, Inc. Many of the OCLC member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. The database includes other information sources in addition to member library collections. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services. WorldCat is used by librarians for cataloging and research and by the general public.
The following tables compare general and technical information for many wiki software packages.
The University of Erfurt is a public university located in Erfurt, the capital city of the German state of Thuringia. It was founded in 1379, and closed in 1816. It was re-established in 1994, three years after German reunification. Therefore, it claims to be both the oldest and youngest university in Germany. The institution identifies itself as a reform university, due to its most famous alumnus Martin Luther, the instigator of the Reformation, who studied there from 1501 to 1505. Today, the main foci centre on multidisciplinarity, internationality, and mentoring.
Java Unified Mapping Program (JUMP) is a Java based vector and raster GIS and programming framework. Current development continues under the OpenJUMP name.
A semantic wiki is a wiki that has an underlying model of the knowledge described in its pages. Regular, or syntactic, wikis have structured text and untyped hyperlinks. Semantic wikis, on the other hand, provide the ability to capture or identify information about the data within pages, and the relationships between pages, in ways that can be queried or exported like a database through semantic queries.
ArcInfo is a full-featured geographic information system produced by Esri, and is the highest level of licensing in the ArcGIS Desktop product line. It was originally a command-line based system. The command-line processing abilities are now available through the GUI of the ArcGIS Desktop product.
Semantic MediaWiki (SMW) is an extension to MediaWiki that allows for annotating semantic data within wiki pages, thus turning a wiki that incorporates the extension into a semantic wiki. Data that has been encoded can be used in semantic searches, used for aggregation of pages, displayed in formats like maps, calendars and graphs, and exported to the outside world via formats like RDF and CSV.
In computing, linked data is structured data which is interlinked with other data so it becomes more useful through semantic queries. It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages only for human readers, it extends them to share information in a way that can be read automatically by computers. Part of the vision of linked data is for the Internet to become a global database.
The history of wikis began in 1994, when Ward Cunningham gave the name "WikiWikiWeb" to the knowledge base, which ran on his company's website at c2.com, and the wiki software that powered it. The wiki went public in March 1995, the date used in anniversary celebrations of the wiki's origins. c2.com is thus the first true wiki, or a website with pages and links that can be easily edited via the browser, with a reliable version history for each page. He chose "WikiWikiWeb" as the name based on his memories of the "Wiki Wiki Shuttle" at Honolulu International Airport, and because "wiki" is the Hawaiian word for "quick".
A cloud database is a database that typically runs on a cloud computing platform and access to the database is provided as-a-service. There are two common deployment models: users can run databases on the cloud independently, using a virtual machine image, or they can purchase access to a database service, maintained by a cloud database provider. Of the databases available on the cloud, some are SQL-based and some use a NoSQL data model.
Wikidata is a collaboratively edited multilingual knowledge graph hosted by the Wikimedia Foundation. It is a common source of open data that Wikimedia projects such as Wikipedia, and anyone else, is able to use under the CC0 public domain license. Wikidata is a wiki powered by the software MediaWiki, including its extension for semi-structured data, the Wikibase. As of mid-2024, Wikidata had 1.57 billion item statements.
Foswiki is an enterprise wiki, typically used to run a collaboration platform, knowledge base or document management system. Users can create wiki applications using the Topic Markup Language (TML), and developers can extend its functionality with plugins.
Wikibase is a set of MediaWiki extensions for working with versioned semi-structured data in a central repository. It is based upon JSON instead of the unstructured data of wikitext normally used in MediaWiki. Its primary components are the Wikibase Repository, an extension for storing and managing data, and the Wikibase Client which allows for the retrieval and embedding of structured data from a Wikibase repository. It was developed for and is used by Wikidata, by Wikimedia Deutschland.
WikiTree is a genealogy website that allows users to research and to contribute to their own family trees while building and collaborating on a singular worldwide family tree within the same system. WikiTree is free for the user and financed via advertisements displayed to unregistered users. WikiTree is owned and hosted by founder's company Interesting.com, Inc.
Freedcamp is a web, mobile and desktop project management and collaboration system for teams. The company was launched in 2010 in Santa Barbara, California by founder Angel Grablev.
A low-code development platform (LCDP) provides a development environment used to create application software, generally through a graphical user interface. A low-coded platform may produce entirely operational applications, or require additional coding for specific situations. Low-code development platforms are typically on a high abstraction level, and can reduce the amount of traditional time spent, enabling accelerated delivery of business applications. A common benefit is that a wider range of people can contribute to the application's development, not only those with coding skills, but good governance is needed to be able to adhere to common rules and regulations. LCDPs can also lower the initial cost of setup, training, deployment, and maintenance.
