6. A non-transitory computer readable medium comprising: computer readable code, that when executed causes a processor in a computer system to implement a method comprising: receiving a user-provided plain language calculation expression, wherein the user-provided plain language calculation expression specifies a plurality of calculation identifiers without specifying at least one calculational relationship between a first calculation identifier in the plurality of calculation identifiers and a second calculation identifier in the plurality of calculation identifiers; determining the at least one calculational relationship in accordance with system-provided definitions; generating a calculation definition table in accordance with the user-provided plain language calculation expression, wherein the calculation definition table comprises the plurality of calculation identifiers and the at least one calculational relationship; determining a calculational sequence associated with the plurality of calculation identifiers; generating a calculation input definition table in accordance with the calculation definition table, wherein the calculation input definition table comprises multiple calculation input definitions each associated with one of the calculation identifiers and the calculational sequence; and generating, a calculation execution graph in accordance with the calculation input definition table, wherein the calculation execution graph is readable by a plurality of enterprise applications and wherein generating the calculation execution graph comprises generating a calculation definition model comprising a plurality of calculation definitions, wherein each of the calculation definitions is associated with a calculation identifier and a length designation, wherein the length designation corresponds to a number of intermediate calculations required for an input required by the calculation definition.
