Connection Prerequisites

You connect to the mart on the server through the client software contained in CA ERwin Data Modeler Workgroup Edition or CA ERwin Data Modeler Navigator Edition. You must perform the following tasks before you can connect to the mart through the client:

• The administrator of the relational database management system (DBMS) must give users permission to access the DBMS on which the mart database is set up.
• The mart administrator must install the administrative files and Initializer license on the server, and set up the database. The administrator also defines user security permissions and sets up the library structure in which models are organized. When you install the CA ERwin Data Modeler Workgroup Edition software, the administrator is automatically granted Administrator security status. This lets the administrator assign user permissions and perform all required maintenance or administrative tasks.
• At least one of the client programs must be installed on the client workstation. System requirements for the client workstations are the same as those for the CA ERwin Data Modeler Workgroup Edition client software. You can find the requirements in the documentation provided with these products.

  Note: CA ERwin Data Modeler Workgroup Edition users can only connect to a mart initialized with the same serial number identifier that the user has licensed on their local PC.

• The client connectivity software for your DBMS on the server must be installed on the client workstation so that you can connect to the DBMS on which the database resides.
