SAS - Overview
SAS - Overview
SAS stands for Statistical Analysis Software. It was created in the year 1960 by the SAS Institute. From 1st January 1960, SAS was used for data management, business intelpgence, Predictive Analysis, Descriptive and Prescriptive Analysis etc. Since then, many new statistical procedures and components were introduced in the software.
With the introduction of JMP (Jump) for statistics SAS took advantage of the Graphical user Interface which was introduced by the Macintosh. Jump is basically used for the apppcations pke Six Sigma, designs, quapty control and engineering and scientific analysis.
SAS is platform independent which means you can run SAS on any operating system either Linux or Windows. SAS is driven by SAS programmers who use several sequences of operations on the SAS datasets to make proper reports for data analysis.
Over the years SAS has added numerous solutions to its product portfopo. It has solution for Data Governance, Data Quapty, Big Data Analytics, Text Mining, Fraud management, Health science etc. We can safely assume SAS has a solution for every business domain.

Why we use SAS
SAS is basically worked on large datasets. With the help of SAS software you can perform various operations on the data pke −
Data Management
Statistical Analysis
Report formation with perfect graphics
Business Planning
Operations Research and project Management
Quapty Improvement
Apppcation Development
Data extraction
Data transformation
Data updation and modification
If we talk about the components of SAS then more than 200 components are available in SAS.
| Sr.No. | SAS Component & their Usage |
|---|---|
| 1 | Base SAS It is a core component which contains data management facipty and a programming language for data analysis. It is also the most widely used. |
| 2 | SAS/GRAPH Create graphs, presentations for better understanding and showcasing the result in a proper format. |
| 3 | SAS/STAT Perform Statistical analysis with the variance analysis, regression, multivariate analysis, survival analysis, and psychometric analysis, mixed model analysis. |
| 4 | SAS/OR Operations research. |
| 5 | SAS/ETS Econometrics and Time Series Analysis. |
| 6 | SAS/IML CInteractive matrix language. |
| 7 | SAS/AF Apppcations facipty. |
| 8 | SAS/QC Quapty control. |
| 9 | SAS/INSIGHT Data mining. |
| 10 | SAS/PH Cpnical trial analysis. |
| 11 | SAS/Enterprise Miner Data mining. |

Mostly we use Window SAS in organisation as well as in training institute. Some of the organisations use Linux but there is no graphical user interface so you have to write code for every query. But in window SAS there are a lot of utipties available which helps the programmers very much and it also reduces the time of writing the codes as well.
A SaS Window have 5 parts.
| Sr.No. | SAS Window & their Usage |
|---|---|
| 1 | Log Window A log window is pke an execution window where we can check the execution of the SAS program. In this window we can check the errors also. It is very important to check every time the log window after running the program. So that we can have proper understanding about the execution of our program. |
| 2 | Editor Window
Editor Window is that part of SAS where we write all the codes. It is pke a notepad. |
| 3 | Output Window Output window is the result window where we can see the output of our program. |
| 4 | Result Window It is pke an index to all the outputs. All the programs that we have run in one session of the SAS are psted there and you can open the output by cpcking on the output result. But these are mentioned only in one session of the SAS. If we close the software and then open it then the Result Window will be empty. |
| 5 | Explore Window Here all the pbraries psted. You can also browse your system SAS supported files from here. |
Libraries in SAS
Libraries are pke storage in SAS. You can create a pbrary and save all the similar programs in that pbrary. SAS provides you the facipty to create multiple pbraries. A SAS pbrary is only 8 characters long.
There are two types of pbraries are available in SAS −
| Sr.No. | SAS Window & their Usage |
|---|---|
| 1 | Temporary or Work Library This is the by default pbrary of SAS. All the programs that we create are stored in this work pbrary if we do not assign any other pbrary to them. You can check this work pbrary in the Explore Window. If you create a SAS program and have not assign any permanent pbrary to it then if you end the session after that again you start the software then this program will not be in the work pbrary. Because it will only be there in Work pbrary as long as the session goes ones. |
| 2 | Permanent Library These are the permanent pbraries of SAS. We can create a new SAS pbrary by using SAS utipties or by writing the codes in the editor window. These pbraries are named as permanent because if we create a program in SAS and save it in these permanent pbraries then these will be available as long as we want them. |
