Review the Prerequisites for a PostgreSQL Mart

Before you install the Mart components, help ensure that the minimum system requirements that are outlined in this topic are met.

You can use any of the following combinations to install erwin Data Modeler, the Mart database, and the Mart Portal application:

  • Install erwin Data Modeler, the Mart database, and the Mart Portal application on the same computer.
  • Install erwin Data Modeler, the Mart database, and the Mart Portal application on different computers.
  • Install erwin Data Modeler and the Mart database on one computer, and install the Mart Portal application on a different computer.
  • Install erwin Data Modeler on one computer, and install the Mart database and the Mart Portal application on a different computer.

Ensure that you always install the Mart Portal application on Windows operating system.

System requirements to install the Mart Portal application

Hardware requirements (based on physical hardware performance, not a virtual environment):

Hardware requirements (based on physical hardware performance, not a virtual environment):

  • 4 GHz or higher quad-core processor
  • 16 GB RAM
  • 100 GB of disk space or more as required to support your specific mart

Operating system:

  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2019
  • Microsoft Windows Server 2022
  • Microsoft .NET Framework 4.0 and above
  • All current Microsoft Windows critical updates are applied

Database:

  • The Mart Portal can use a standalone or can share an existing database server for PostgreSQL certified versions 15.3, 14.8, 13.11, 12.15 and 11.20 databases for the Mart database. You can also use PostgreSQL certified version 11.8 for Amazon Aurora.
  • The database user account that is used to configure the Mart must have super user permissions.

erwin Mart Portal web client:

Supported browsers:

  • Microsoft Edge v97 or newer
  • Mozilla Firefox v91 or newer
  • Google Chrome v97 or newer
  • Apple Safari 15 or newer

Ensure that your screen resolution is 1024 x 768 or higher. If your screen resolution is less than the minimum supported, some portions of the screen will not be visible.

Other requirements

Help ensure that the following additional requirements are met:

  • The DBMS is installed and prepared for creating the Mart Database.
  • The Mart database is created. At least one user with administrator privileges is present.
  • If you want to add Windows Group users as Mart users, you have the Active Directory Server details.

    You can add Windows Group users as normal Mart users, but not as Mart administrators. A Mart administrator must be a server or Windows user.

Important disclaimer notice on all requirements

  1. The requirements that are mentioned previously define the minimum requirements which permit the application to run with reasonable performance based on a small business use case scenario. The actual requirements for an enterprise-wide use case based on larger models and configurations require significantly greater resources to obtain acceptable performance.
  2. These requirements are based on actual physical hardware (no virtual environment) and the following assumptions:
    • Minimal to no network overhead (both the database and application servers are locally installed)
    • Vendor's default install of the current version of their software (with all current service or fix packs)
    • No other applications sharing the defined hardware configuration (for example, a clean machine)

    Any other hardware/software configurations are acceptable as long as they provide the same (or better) performance characteristics identified.
