What is SAS?

SAS (Statistical Analysis System) is statistical software designed for data inspection and report writing. SAS runs on Windows, UNIX and can be downloaded into Mainframe too. This is an integrated software suite that enables us to perform statistical analysis by altering, managing, and retrieving data from a variety of sources to develop a software solution. It provides a graphical point-and-click user interface for non-technical users and more advanced options through the SAS language (A computer programming language used for statistical analysis that can read data from common spreadsheets and databases and outputs the statistical analysis result in tables, graphs, and as RTF, HTML, and PDF documents).

SAS is a batch of a program that works together to reclaim them and to reserve data values, reform data, evaluate complex and single exponential analyses and generate reports. These programs have DATA steps, which retrieve and manipulate data, and PROC steps, which analyze the data.

Why SAS?

Being SAS Professional I can tell you why SAS. I would say, its bit tiny subject however very Unique, competitive and leading within the analytics world. SAS is the main statistic tool certified by the FDA, IIRC.SAS is Statistical Analysis System i.e. a collection of software program tools created by SAS Institute. SAS programming has numerous applications like the analysis of multivariates, predictive analysis, management of data and business intelligence.Statistics show that 70% of analytics jobs are in SAS Programming, followed by R and then Python. It is an ever-evolving technology according to industry needs is one major factor in its favour.

SAS Job Profiles

Below are some of the job profiles you can take up as a SAS professional:

  • SAS Analyst
  • SAS Programmer
  • Customer Analytics Manager
  • Decision Analyst

There is a huge scope of SAS for fresher. Banks are heavily using SAS as are Insurance & other Financial Services companies like HSBC, Citi, JP Morgan, & Wells Fargo.So it’s sensible to grab the opportunity if you get it by some means to learn and work on SAS technology.

SAS Modules

When you install SAS software, it has several in-built modules which are designed for various analytics and reporting purposes. See some of the common SAS modules or components.



It is the most common SAS module. It is used for data manipulation such as filtering data, selecting, renaming or removing columns, reshaping data etc.



It runs popular statistical techniques such as Hypothesis Testing, Linear and Logistic Regression, Principal Component Analysis etc.



It lets you read data from databases such as Teradata, SQL Server, Oracle DB2 etc.



You can create simple and complex graphs using this component.



You can perform time series forecasting such as ARIMA, Exponential Smoothing, Moving Average etc. using this module.
