From release 9.0 onward, the way you access the Model Manager has changed. In fact the term Model Manager is also no longer used—it is now called the Mart. The Mart is built on a three-tier architecture, which includes a database, a web server, and a client. You may have seen the term MartServer in the installation documents and you may have looked for its meaning.
The term MartServer refers to the software that helps you connect a database to a client, through a web server. To understand this better, consider the Mart architecture as three layers of sheets, Sheet 1, Sheet 2, and Sheet 3. Assume that Sheet 1 is at the bottom and Sheet 3 is at the top.
- Sheet 1 refers to the Mart database. You install database software and create a database to use as the Mart. It can be an Oracle, a Microsoft SQL Server, or a Sybase Adaptive Server database.
- Sheet 2 refers to the web server. The web server is the software that connects the Mart database with the client. You can use the default web server (Tomcat) that comes with the Mart, or install a web server of your choice.
- Sheet 3 refers to the client. CA ERwin Mart Administrator and CA ERwin Data Modeler both are clients. CA ERwin Mart Administrator is installed when you install Mart Server.
MartSever is not a computer, it is a software program. It helps you connect to the Mart database from CA ERwin Mart Administrator and CA ERwin Data Modeler, through Tomcat (default web server). When you install MartServer, CA ERwin Mart Administrator is installed.
