Abstract
Methods are provided for improving the ability to apply modeling techniques similar to relational algebra to an expanded number of workflows. By allowing a relational algebra type modeling technique to be applied to an expanded number of workflows, an increased number of data processing workflows can be more readily improved, such as by automatic modification of the sequence of tasks in a workflow, to reduce the execution costs for a workflow. The relational algebra type modeling technique can also allow for identification of portions of data processing workflows or queries that share a common input and output.
