The Data Migration Process flow diagram depicts data flow from the source to the target applications. By visualizing the spread of sources/targets, the Data Migration Process flow diagram can serve as a tool for data auditing and establishing traceability. This data flow diagram can be expanded or improved as much as needed. The chart, for example, could include only an overall layout of the migration landscape or could go into detail about individual application metadata elements. Data migration can be expressed on three levels: conceptual, logical, and physical. Application communication diagrams can also be utilized to define data migration. The most important factor in formalizing migration is migration dependency. Download EdrawMax today and create a complex data flow diagram to showcase any process.
