Comparison : : Assessing Support for Top-Down Data Modeling in Two Leading Tools

ER/Studio and erwin Data Modeler are long-standing players in the data modeling tools market, focusing completely on the production of Logical Data Models (LDMs) and Physical Data Models (PDMs). Both tools have powerful utilities for building models and databases, but data professionals choosing between them may want to know more about the specifics of their performance.

In this whitepaper, you’ll learn how ER/Studio and erwin Data Modeler compare when building databases using two distinct approaches – Silo Design and Enterprise Logical Data Model (ELDM)-Driven Modeling – and how they perform when:

  • Building and editing LDMs
  • Generating, updating, and denormalizing PDMs
  • Creating databases
  • Merging selected parts of LDM into ELDM
