Maintaining Environments

Overview

After you have created a project plan for a data warehouse or a data mart, you are ready to begin work in SAS/Warehouse Administrator. For each data warehousing project, you will create a hierarchy of groups and data stores in the SAS/Warehouse Administrator Explorer, such as the hierarchy that is shown in Warehouse Environment in the Explorer.

The first object that you create will be a Data Warehouse Environment. A Data Warehouse Environment is a metadata record that specifies the SAS library _MASTER. The _MASTER library is the metadata repository for host definitions and other global metadata that is shared among one or more Data Warehouses and Operational Data Definition Groups (ODD Groups).

In a broad sense, creating a Warehouse Environment includes defining the global metadata and the data sources for the Environment. These topics are covered in other chapters. This chapter focuses on the Warehouse Environment object that defines the _MASTER metadata repository.

To create a Warehouse Environment:

Create a directory structure for the Warehouse Environment.
Define the properties of the Warehouse Environment.
Create a start method for the Environment, if one is required.

Note: The basic steps for maintaining Warehouse Environments are described in the online Help. To display the relevant online help, in the SAS Help contents, select Help on SAS Software Products, then select Using SAS/Warehouse Administrator Software. Select Setting Up Your Warehouse Environment, then Maintaining Warehouse Environments. In addition, you can display Help for most SAS/Warehouse Administrator windows by selecting Help on the window.
