What's New in Base SAS 9.0 and 9.1: Overview

Open Metadata Architecture

The SAS Open Metadata Architecture enables you to set up a metadata server, create metadata repositories, and write applications (clients) that use, store, or manage the metadata.

SAS Management Console

SAS Management Console is a Java application that provides a single point of control for administering SAS metadata. The application provides a flexible administrative environment through the use of plug-ins.


New multi-threading capabilities improve processing time for the SORT, SQL, MEANS, TABULATE and REPORT procedures.

The new DOCUMENT procedure enables you to customize or modify your output hierarchy and replay your output to different destinations without rerunning the PROC or DATA step. Enhancements to the TEMPLATE procedure enable you to customize or create your own markup language for your output.

Other enhancements to Base SAS procedures improve ODS formatting, enable import and export of Microsoft Excel 2002 spreadsheets and Microsoft Access 2002 tables, support long format and informat names, list and compare SAS registries, enhance statistical processing, and enhance printer definitions.

Language Elements

New language elements enable the monitoring of application transactions and performance, enable parallel process using threaded technology, provide Secure Sockets Layer (SSL) access to files as well as access to files using directory services, improve searching and manipulating of data, and provide new statistical and mathematical functions.

New engines enable the use of a broader variety of XML documents, provide access to metadata in a SAS Metadata Repository, and improve performance by using multiple CPUs to read SAS data.

In the Output Delivery System, SAS 9.0 and 9.1 provide an array of markup languages including HTML4 and XML. The new ODS GRAPHICS statement (Experimental) now enables you to produce graphics output. The new ODS DOCUMENT destination gives you more control over the structure and hierarchy of your output.
