PowerDesigner provides powerful tools for analyzing the dependencies
between model objects.
When you perform an action on a model object, in a single operation you can
produce both:
- Impact Analysis – to analyze the effect of the action on the objects that
depend on the initial object.
- Lineage Analysis – to identify the objects that influence the initial
object.
These tools can help you answer questions like these:
- If I change the precision on a column in my ASE model which I
generated from the ESP schema model, what table columns in my
SAP Sybase IQ or SAP HANA model must also
change, and what schema are affected?
- Which schema fields influence each column in my ASE, SAP HANA,
and SAP Sybase IQ models?
- If I delete a column from my IQ model, what is the impact on
tables and columns in my ASE and SAP Sybase IQ
models, and what schema definitions must change in my
ESP Schema model?
