Improving the Development Process
Process modeling is a tried and proven approach that works well with Information Technology applications such as data integration. By applying a process modeling technique to data integration, both the visualization and standardization issues will be addressed. First, let's review the types of process modeling.
Leveraging Process Modeling for Data Integration
Process modeling is a means of representing the interrelated processes of a system at any level of detail, using specific types of diagrams that show the flow of data through a series of processes. Process modeling techniques are used to represent specific processes graphically for clearer understanding, communication, and refinement between the stakeholders that design and develop system processes.
Process modeling unlike data modeling has several different types of process models based on the different types of process interactions. These different model types include process dependency diagrams, structure hierarchy charts, and data flow diagrams. Data flow diagramming, which is one of the best known of these process model types, is further refined into several different types of data flow diagrams, such as context diagrams, Level 0 and Level 1 diagrams and "leaf-level" diagrams that represent different levels and types of process and data flow.
By leveraging the concepts of different levels and types of process modeling, we have developed a processing modeling approach for data integration processes, which is as follows:
