Process Querying combines concepts from Big Data and Process Modeling and Analysis with Business Process Intelligence and Process Analytics to study techniques for retrieving and manipulating models of processes, both real-world and envisioned, to systematically organize and extract process-related information for subsequent use.

PQL Screencasts

Process Query Language (PQL) is a special-purpose programming language for managing process models based on information about process instances that these models describe. PQL is based upon temporal logic and adopts the concrete syntax of SQL.

The PQL Tool is an open-source initiative that works onĀ  implementing an environment for executing PQL queries. The projected is hosted here.

The screencast below demonstrates the integration and usage of the PQL Tool in the open source process model repository Apromore.
