+LibDataBroker is a small WoW addon library designed to provide a "MVC":http://en.wikipedia.org/wiki/Model-view-controller interface for use in various addons. +LDB's primary goal is to "detach" plugins for TitanPanel and FuBar from the display addon. +Plugins can provide data into a simple table, and display addons can receive callbacks to refresh their display of this data. +LDB also provides a place for addons to register "quicklaunch" functions, removing the need for authors to embed many large libraries to create minimap buttons. +Users who do not wish to be "plagued" by these buttons simply do not install an addon to render them. + +Due to it's simple generic design, LDB can be used for any design where you wish to have an addon notified of changes to a table. + +h2.
