1. In a computing system comprising a memory and one or more processors, a method of processing, in parallel, a plurality of database operations modifying values of a plurality of data recipients based at least in part on values of associated data sources, the method comprising: receiving a request to execute a rule specifying an allocation of values between a plurality of data sources and a plurality of data recipients, each data source having a data source identifier and associated with one or more values in one or more tables of a database system, each data recipient having a data recipient identifier and associated with one or more values in one or more tables of the database system; distributing each of the data source identifiers to one of a plurality of tasks, each task comprising at least one data source identifier; for each of the plurality of tasks, at least a portion of the plurality of tasks being executed in parallel, for each data source identifier of a respective task: from the rule, identifying one or more data recipients for the data source identifier; from the rule, determining a tracing factor associated with the data source identifier; generating a pinpoint query, the pinpoint query defining one or more database operations to retrieve data from one or more database tables of the database system based on the data source identifier and the identified one or more data recipient identifiers; executing the pinpoint query on the one or more database tables to retrieve data associated with the data source identifier and the identified one or more data recipient identifiers; and disaggregating at least one value provided by retrieved data for the data source identifier by applying at least one mathematical operator, specified by the tracing factor, to the at least one value and retrieved data values for at least one of the identified data recipient identifiers, the disaggregating providing a modified data source value and at least one modified data recipient value; and posting the modified data source values and the modified data recipient values to the database system.
