The solutions of the Einstein-Maxwell system of equations, useful for the modeling of compact stars have a long and rich history. It took just a year since Einstein’s general theory of relativity was published for Karl Schwarzschild to obtain the first exact solution of Einstein’s field equations. The number of viable exact solutions has been growing since then. Different models have been constructed for a variety of applications. In this article, we have discussed different ways of generating a static spherically symmetric anisotropic fluid model. The purpose of the present article is to present a simple classification scheme for static and spherically symmetric anisotropic fluid solutions. The known solutions are reviewed and compartmentalized according to this scheme so that we can illustrate general ideas about these solutions without being exhaustive.
