Architecture

When users generate a report, CA ERwin Version 9 Mart retrieves data from the Mart Server via web services.

The components involved in reporting are as follows:

• A Reporting tool that can report on XML data; for example Crystal Reports.
• Mart Server, which is a component of CA ERwin Version 9 Mart installation.
• Mart database, which is the data source for the Mart Server.

CA ERwin DM Release 8 Mart reported directly against the Mart database. This approach is changed in CA ERwin DM Version 9 Mart.

The following steps describe the process of generating reports in CA ERwin DM Version 9 Mart:

1. Reporting tools such as Crystal Reports connect to the Mart Server through web services.
2. The web services return the report information in XML data format.
3. Reporting tools use this XML information as the dataset and display the report.

The following diagram illustrates the reporting architecture:
