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 MartServer application:

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

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

System requirements to install the MartServer application

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

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

  • 2 GHZ or higher dual core processor
  • 4 GB RAM (8 GB or more for large marts)
  • 4 GB of disk space or more as required to support your specific mart

Operating system:

  • Microsoft Windows 7 SP1
  • Microsoft Windows 8.1
  • Microsoft Windows 10
  • Microsoft Windows Server 2008 R2 SP1
  • Microsoft Windows Server 2012, R2
  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2019
  • Microsoft .NET Framework 4.0 and above
  • All current Microsoft Windows critical updates are applied

Database:

  • The Mart Server can use a standalone or can share an existing database server for PostgreSQL through Release 9.6.2 database. Also, it is certified on PostgreSQL Release 9.6.15, 10.10, and 11.5.
  • The database user account that is used to configure the Mart must have super user permissions.

erwin Mart Administrator web client:

Supported browsers:

  • Microsoft Internet Explorer v10 or newer
  • Mozilla Firefox v30 or newer
  • Google Chrome v30 or newer
  • Apple Safari 6 or newer

Note: 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:

  • If you want to use Microsoft IIS as the web server, you have configured it.
  • 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.

    Note: 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.
