System and method for management system data aggregation and transformation using client-specific criteria

A method may include receiving, at a first time, an instruction to execute a stored procedure at a database system, retrieving a schema of a structure of a database used by a management system of a client entity, determining an identity of a management system and a type of data to retrieve for the client entity. The method may also include, responsive to determining the identity and the type of data to retrieve, determining a criteria to use in a dynamic query based on the identity and the type of data to retrieve. The method may also include, responsive to determining the criteria, generating, in the stored procedure, the dynamic query comprising the criteria, and executing the stored procedure to retrieve raw data from the database used by the management system and transform the raw data to transformed data using the dynamic query.
