The development of an application, or website, begins with the creation of a number of special XML definition files are used to delineating the logic and configuration of the application. Once configuration is complete, the build process is activated which renders, or compiles the application from XML into PHP.

One of the goal of nexista is to provide the backbone of the application such as handling database connections and queries, data validation, etc... without constraing the developers. For example, user authentication and caching logic is created by the developer in whatever manner they prefer and later 'hooked' into Nexista.
