Event data associated with state data corresponding to an instance of a process is collected by an interceptor associated with a server that performs an operation to modify the state data. The server performs a single transaction with the database to store both the modified state data and the associated event data, the transaction either succeeding or failing, whereby if the transaction succeeds, then both the state data and the event data are stored at the database, and if the transaction fails, then both the state data and the event data are not stored at the database. The event data stored at the database is then transmitted to a tracking service for conversion into a query-able format.
