<h1>Specific Topics</h1>


<span class="secondo">Secondo</span> can be extended by algebra modules. Such an algebra
provides some new data types and operators. It can use the
types of other algebras. Operators are directly available
in the executable language of <span class="secondo">Secondo</span> and partially also in the Optimizer. In this section, we provide
some files describing specific algebra modules:

<h2>Viewer-Specific Documentation</h2>

The graphical user interface of <span class="secondo">Secondo</span> can be extended by so-called
viewers able to present different data types. On this page, we provide documents describing
such viewers.
