Base SAS software provides you with essential tools for the basic data-driven tasks that you commonly perform as a programmer:

You can access data that is stored almost anywhere, whether it is in a file on your system, or data that is stored another database system.
In almost any format, including raw data, SAS data sets, and files created by other vendors' software.

RDBMS-Oracle,sql,teradata etc.,
NonDBMS-pc files(excel,access etc.,)
ERP Systems-SAP/BW,PS,Baan etc.,

After you have accessed your data, you can use the SAS programming language to manipulate it.
Format your data ,create variables (columns), use operators to evaluate data values ,use functions to create and recode data values, subset data, perform conditional processing,merge a wide range of data sources, create, retrieve, and update database information.

Once your data is in shape, you can use SAS to analyze data and produce reports. Your SAS output can range from a simple listing of a data set to customized reports of complex relationships.

23
Base SAS provides powerful data analysis tools. For example, you can produce tables, frequency counts, and cross-tabulation tables
create a variety of charts and plots
compute a variety of descriptive statistics, including the mean, sum, variance, standard deviation and more
compute correlations and other measures of association, as well as multi-way cross-tabulations and inferential statistics.

For reporting and displaying analytical results, SAS gives you an almost limitless number of visually appealing output formats, such as an array of markup languages including HTML4 and XML output that is formatted for a high-resolution printer, such PostScript, PDF, and PCL files RTF color graphs that you can make interactive using ActiveX controls or Java applets.
