Data evaluations require user specifications that describe the scope and type of each evaluation. In most cases, a basic type of specification can be defined for a particular evaluation, e.g. the specification of a key date. In addition, there are usually a number of variants that differ only in the dates of the specifications, e.g. which date is to be used as the key date. These can be fixed defaults (e.g. the specification of a certain key date) or defaults that are calculated (e.g. the end of the previous month). The goal of the bachelor thesis is to develop an application to manage such configurations based on configuration types with any number of configuration elements.
