The information in this wiki hasn't been maintained for a good while. Some of the projects described have since been deprecated.
In particular, the "Ushahidi Platform v3.x" section contains information that is often misleading. Many details about this version of Platform have changed since.
This website is an extraction of the original Ushahidi wiki into a static form. Because of that, functions like logging in, commenting or searching will not work.

Here is an outline and description of database tables created during installation of the Ushahidi Platform version 2.7.2 from the Ushahidi downloads page (Master branch), and from Github (Develop branch).
