Computer implemented method for creating database structures without knowledge on functioning of relational database system

A computing device program product for storing ad hoc relations between previously unrelated database objects assigned to two unrelated data sets, the computing device program product comprising:

• a non-transitory computer readable medium having instructions stored thereon that when executed by a processor cause operations to execute the instructions, the instructions comprising;
• first programmatic instructions for creating an ad hoc relation between a first data set and a third data set that are previously unrelated, wherein the ad hoc relation comprises at least i) a first relation between the first data set and a second data set, ii) a second relation between the second data set and the third data set and iii) a filtering condition on the first data set or on the second data set;
• and
• second programmatic instructions for storing the ad hoc relation between the first data set and the third data set in a file, wherein the file defines the ad hoc relation by at least storing the first relation, the second relation and the filtering condition.
