Abstract
Systems and processor-implemented methods of S-expression based computation of lineage and change impact analysis. An SQL expression is converted into an S-expression tabular structure. A function table including a plurality of functions associated with S-expression tabular structure tabulated against at least one of a function name, a derived column and a derived table and an argument table including plurality of arguments associated with the S-expression tabular structure tabulated against at least one of an argument type, a function identifier linking the arguments to the function table, a computed from function, a reference to entity or a literal value, is generated based on the S-expression tabular structure. At least one of lineage or change impact analysis for an entity is determined based on the function table and the argument table, where lineage provides a provenance of the entity or attribute from a source entity or a source attribute.
