Method for the efficient analysis of process data

A computer-implemented method for storing process data in a computer system for efficient analysis of process data, wherein the process data is generated by executing real processes, and is stored as a component of source data in at least one source system, wherein the computer system comprises a processor and a storage means coupled to the processor operatively, wherein the process data comprise a number of process instances, wherein each process instance comprises a number of process steps, wherein the method comprises:

• allocating, by the processor, a storage area for the process data in the storage means;
• loading, by the processor, the source data comprising the process data, from the at least one source system, and storing the process steps of the source data according to a predetermined data structure in the allocated storage area of the storage means, wherein the loading of source data and the storing of process steps in the allocated storage area of the storage means comprises a step, in which the process steps of the source data are transformed into the predetermined data structure, wherein the predetermined data structure comprises at least:
• a first attribute, in which a unique identification of the process instance of the respective process step is stored;
• a second attribute, in which an identification of the respective process step is stored;
• and
• a third attribute, in which the sequence of the process steps within a process instance is stored;
• sorting, by the processor, the process steps in the allocated storage area, wherein the process steps, at first, are sorted according to the first attribute, and subsequently, according to the third attribute physically, wherein subsequent process steps of a process instance are stored in directly adjacent storage sections of the allocated storage area.
