Understand Licensing

erwin offers the following license types based on erwin Data Modeler (erwin DM) editions:

  • Standard
  • Workgroup
  • Navigator
  • API
  • Trial
  • Evaluation (15 days)
  • Academic (365 days)
  • Industry Reviewer (60 days, full-featured)
  • Partner (365 days, full-featured)

Further, each edition-based license can belong to either of the following licensing models:

Concurrent

This licensing model is based on a pool of licenses shared between several users. Simultaneous access to the erwin DM is available to as many users as the number of allowed users on a concurrent license. For example, if you have a ten-user concurrent license, ten users can access erwin DM at a time using the license. Therefore, if an eleventh user tries to use erwin DM, access is denied.

Node-locked

This licensing mechanism uses your device ID and user account to let you use the license and grant access to the erwin DM. Such licenses cannot be shared between users on different devices unless a user returns the license. However, there is a restriction on the number of times you can return a node-locked license. If you are unable to return your license, submit a request to erwin Support.

Account Based Licensing

Both concurrent and node-locked license models support the Account-based Licensing (ABL) model. This licensing model is based on the credential-based login-and-use mechanism. Under this model, a single license is shared between multiple users within a group. To know how the node-locked licensing model works, refer to the Node-locked section.

The workflow of this model is as follows:

  1. Each organization has one master group and multiple user groups under the master group.

  2. Each user group is assigned with a unique license code and each user receives license credentials.

  3. Individual users log on and use erwin DM application using their license credentials.

ABL enables you to manage your licenses via an End User Portal (EUP). This puts your Master User in charge of your licensing and consumption report generation. ABL makes you self-reliant with convenient license assignments and maintenance. It enables you to manage your licenses, run usage reports, and manage users. Apart from this, you can import users to groups via an MS Excel file. For erwin DM users, it eliminates the dependency on license codes.

For more information on how to set up ABL for your organization, refer to the Configuring Account Based Licensing Topic.

License Activation

Both concurrent and node-locked licensing models (except ABL) let you activate licenses using either of the following mechanisms:

Online

This method connects to the licensing service over the Internet. The licensing service then validates and activates the license code that you entered.

Offline

This method uses a multi-step activation process as follows:

  1. User generates an activation certificate and sends it to the license administrator.
  2. License administrator generates a license certificate and sends it to the user.
  3. User imports the license certificate to activate the license code.

Each license comes with a maintenance period. Along with the product, a year of support is included. Any product updates that are released during the registered maintenance/support period are made available. Once the maintenance/support period is over, you need to renew the maintenance plan to be able to receive updates and support. To keep a track of the maintenance period, erwin DM lets you set a maintenance expiration reminder.

Your license administrator needs to ensure that the Maintenance End Date is set. Else, your license will fail.

For each type of license, you can implement usage restriction based on network domain name or subnet IP.
