"The NEDM project has been very helpful in the ongoing expansion of the eScholar Complete Data Warehouse. By leveraging the work of the NEDM in finding commonality among education data attributes across disparate systems and organizations, we are able to more quickly deliver broadly applicable enhancements."
-Shawn Bay
 Founder/CEO, eScholar LLC

“What I’ve found helpful about working with NEDM is that it provides us with a starting point for our work to expand our data system. In New Jersey, we have multiple, fragmented data collections that grew over the years as independent entities. Our challenge is to build out our SLDS to incorporate what we’ve been collecting but also focus on what we may not have been collecting. NEDM is a fabulous tool to help us establish our priorities for which data elements and collections should be incorporated first and also to provide the more global guidance of what the data values and formats should be for each new data element.”

Conceptual Modeling Software

Modeling Software

For more advanced users, the information contained in the Data Model can be displayed in numerous ways depending upon particular needs or interests. There are two “open source” tools that allow the user to accomplish tasks such as using the model to generate:

  • Lists of entities and attributes
  • Entity detail reports
  • Conceptual Maps
  • Filtered conceptual maps, i.e. only small parts of the conceptual map are shown for ease of understanding.
  • Entity taxonomy
  • Relationship diagrams
