Chapter 2   Data Sources and User Privileges


Data mining is the search for relationships and global patterns that exist in large databases. These relationships represent valuable knowledge about the database and objects in the database.

The iPlanet Application Server Enterprise Connector for SAP R/3 does a specialized form of data mining: it looks at data and extracts functions and parameters from backend systems to enable you to utilize (call) these functions.

The tasks are to write functions to access data that defines methods.

This chapter contains the following information:

• Overview of the Management Console

• Mapping User Privileges

Overview of Management Console

---

The management console has two groups of functions:

• Tasks that are used to process and browse data and functions: data mining, browse archived XML files, and add new data sources.

• User management that establishes relationships between the web and backend users.

The user mapping management tasks performed with the management console are explained in this chapter. See the iPlanet Application Server Enterprise Connector for R/3 Developer's Guide for a description of the other tasks of the management console.

Click on the SAP User Mapping icon. The following window displays:

The Data Source Name window displays the following selected data:

Web User Information	The following web user information is listed here: the user's ID, the transaction name, and the entity name.
Entity Information	The following entity information such as the backend user name, and entity name is listed here.

Web User Information

The Web User Information is used to map a web user identity to a backend user identity. The administrator assigns an entity name for the web users. This web ID is used by the server to enable users to move freely across multiple systems. You can add, change users, and delete users and entities from this window. The administrator assigns entity information before the web user information, as one is based upon the parameters defined in the entity information. Because certain web user's parameters are based upon entity information parameters, the administrator must first establish entity information. The Web User Information area lists the following:

Web ID	This is an ID assigned to users on the system.
Transaction Name	This is the name of the function that will be performed. This name is named after the backend system, and order in which it appears.
Entity Name	This is the name of the assigned backend user. The naming process is dependent upon the database type used.

Editing a Web User

You can add a new web user, change a web user, and delete a web user by pressing the corresponding button.
