The simplest online database that would work is wiki. Wiki allows users to use it freely to create and edit. Additionally, wikis between group communications can allow for the organization of contributions for editing the content itself. Therefore, in my essay I will write about the definition of wiki, who uses wikis?, types of wikis, what are the disadvantages? And what is its meaning? The word "wiki" meaning "fast" in the Hawaiian language. It is a server software used to create a website that can allow users to freely create and edit by multiple people from any web browser. Additionally, a popular wiki, a web-based collaborative encyclopedia, was launched in January 2001, called Wikipedia. Additionally, Wiki was a side project of Jimmy Wales and Larry Sanger's Nupedia. Wiki is the most popular on the public web in terms of page views. Additionally, wiki is a web application that allows multiple people to easily contribute to the same document and add, edit, or delete that document.

In conclusion, Wiki is a useful tool that allows people from all over the world to collaborate on a single project. The platform can be difficult to learn, but once obtained it can be used by anyone for educational, informational and editorial activities. In my opinion, the characteristics of a wiki are the ease of editing and collaboratively creating documents, the ability to update content, and the ability to find content through search and navigation. Also, wiki has the disadvantage that anyone can edit websites, so there is no privacy. Requires Internet connectivity to collaborate with others.
