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, what
table columns in my Sybase IQ model must also change, and what schema are
affected?
- Which schema fields influence each column in my ASE and Sybase
IQ models?
- If I delete a column from my IQ model, what is the impact on
tables and columns in my ASE and Sybase IQ models, and what schema definitions
must change in my ESP Schema model?
