Key Requirements for Any Data Modeling Tool Every profession has a set of tasks that are especially important to it, and data modeling is no different. All three tests involved modeling for a Microsoft SQL Server 2008 environment. This review will compare CA ERwin Data Modeler r8 (CA ERwin), newly released in February 2011, with two other popular modeling tools Sybase‘s PowerDesigner v15.3.0 (PowerDesigner) and Embarcadero Technologies‘ ER/Studio Data Architect 9.0.1 (ER/Studio). For these and other reasons, selection of the right data modeling tool is critical. And, as non-technical business users become frequent users of data modeling toolsets and the valuable visualization capabilities they provide, ease of use becomes a key consideration. The data modeling tool is best suited for filling this role because it houses key metadata and can provide the cleanest, clearest conceptual view of business-critical systems. It is, however, the data modeling tool that provides the most comprehensive picture of where the data is, what it looks like, and how best to manage it. Several tools in today‘s environment contribute to that overall process, including the DBMS itself, front-end applications, ETL tools, back-end reporting tools and data modeling tools. Introduction Today's CIOs must do much more than safeguard company data - they must also understand it in the context of the business while continuously improving its overall quality. Lastly, making the data model metadata available via the Erwin Data Intelligence Suite enables both technical and business users to completely understand everything about the data and data store: Business Glossary, Reference Data, Governance, Data Quality, Data Mapping, and especially automating data lineage and impact analysis.A Usability Comparison of the Top Three Data Modeling Tools Making the data model diagrams transparently accessible via Web Portal is another important step in ensuring both technical and business users understand the structure and relationships of the data contains within a data store. Model Mart) is important for any company. Protecting intellectual property and transparently sharing data model information with other modelers by saving the the models in a centralized location (i.e. With all of the ways we have to program and perform ETL, Erwin Data Modeler has been my tool of choice for any other project throughout the years.

This meant that we could count on PowerDesigner to automatically generate the ddl and pl/sql code in the correct run order, rather than manually maintaining a spreadsheet with the script order and running each script manually, a VERY labor intensive process. I don't know if PowerDesigner still has that capability. PowerDesigner had the ability to store the pl/sql within the data model and prioritize/order the script run sequence. 15 years ago was the one time I chose to use PowerDesigner over Erwin Data Modeler was for a project where we have hundreds of pl/sql ETL scripts that needed to be run in a specific order for specific tables.
