Benefits
Integrate data across environments. Based on an open, cross-platform architecture, Base SAS is hardware-agile and integrates into any computing environment infrastructure, enabling you to unify your computing efforts and get a single view of your date of format.


 我Read, format and analyze any data. From small data issues to large complex data problems, programmers can read, format, analyze and report on data quickly, regardless of format.
 我Make programming fast and easy. With an intuitive, easy-to-learn and easy-to-use programming language, Base SAS significantly reduces the amount of code required to deliver information. SAS procedures encapsulate and deliver functionality with a few simple commands, increasing your programmers’ productivity.
 我Simplify reporting. Base SAS provides maximum reporting flexibility. You can easily create reports in standard office formats such as Rich Text Format (RTF) and Portable Document Format (PDF), and produce graphs of analytic results automatically from statistical procedures.
 我Maximize use of all computing resources. With multithreaded capabilities, Base SAS software takes advantage of parallel processing power to maximize use of computing resources and produce the timely answers your organization demands.
在集成环境中的数据。基于一个开放的，跨平台的架构，基地SAS是硬件到任何计算环境基础设施，灵活和集成，使您能够为您的计算统一的努力和取得的数据的单一视图。
阅读，格式和分析任何数据。从问题的小型数据大型复杂问题的数据，程序员可以读取，格式，数据分析和报告很快，无论其格式。
使编程快速和容易。有了一个直观的，易于学习和易于使用的编程语言，基地的SAS大大减少了所需的代码量传递信息。的SAS程序封装，并提供了一些简单的命令的功能，增加您的程序员的生产力。
简化报案。基地的SAS提供了最大的灵活性报告。您可以轻松地创建标准的Office格式的报告，如RTF格式（RTF）和便携文件格式（PDF），并产生分析结果的统计程序自动从图表。
最大限度地发挥所有计算资源的使用。随着多线程能力，采取相应的SAS软件的并行处理能力，以最大限度地利用计算资源的使用和生产的要求，及时组织中的答案。


Features
Powerful data analysis capabilities
 Analysis capabilities ranging from simple descriptive statistics to advanced data correlations.
 Library of pre-written programming procedures for managing, analyzing and presenting data.
Flexible 4GL
 Intuitive 4GL with easy-to-learn syntax.
 SAS Macro Facility reduces coding for common tasks and lets you modularize work for easy reuse and maintenance.
 Runs interactively or in batch mode
Support for wide range of data formats
 Ability to read data in any format, from any kind of file, including variable-length records, binary files, free-formatted data and even files with messy or missing data.
 Support for Structured Query Language (SQL).
 Globalization with full support for the most widely used character encodings (such as Latin1, Latin2, and multiple-byte character sets for Hebrew, Arabic and Asian languages).
 Unicode support so that SAS works with data in multiple languages on all platforms.
Performance and scalability
 Parallel I/O optimization lets you work with huge data volumes in a timely manner. Data can be partitioned across devices for faster access, but referenced as a single data set.
 Parallel index creation reduces time needed to create large data sets with multiple indexes or to append data to existing data sets.
 Key SAS procedures are multithreaded for faster execution of standard tasks such as sorting and data summarization.
Interoperability and multiple platform deployment
 MultiVendor Architecture™ allows programs to be written once and run anywhere, regardless of hardware or operating system.
 SAS Open Metadata Architecture enables different applications to exchange metadata.
 Cross-environment data access provides easy-to-access files across a network.
Manageability
 SAS Management Console provides an extensible Java GUI for administering SAS tasks.
 XML engine imports and exports a wide variety of XML documents.
 A drag-and-drop interface creates XML maps.
 Checkpoint and restart capability allows users to resubmit a failed program in restart mode to complete execution, resuming with the step that did not complete when the failure occurred.
 Application Response Measurement (ARM) interface monitors the availability and performance of transactions within and across diverse applications.
Data presentation
 ODS provides an almost limitless number of choices for reporting and displaying analytical results.
 Create reports in standard formats such as RTF and PDF. All formats are available on all platforms.
 Create visually appealing graphics from analytic output by default (no additional programming).
 HTML 4 and XML are among the markup languages provided. Modify any markup language that SAS provides or create your own markup language for output.
 Customize or modify output hierarchy; replay output to different destinations without rerunning the program.
