Barr was joined by student James Goodnight, who developed the software's statistical routines, and the two became project leaders. and was originally intended to analyze agricultural data to improve crop yields. The project was funded by the National Institutes of Health. The development of SAS began in 1966 after North Carolina State University re-hired Anthony Barr to program his analysis of variance and regression software so that it would run on IBM System/360 computers.

The SAS software suite has more than 200 components Some of the SAS components include: It generates code to manipulate data or perform analysis automatically and does not require SAS programming experience to use.

The SAS Enterprise Guide is SAS's point-and-click interface. SAS data can be published in HTML, PDF, Excel, RTF and other formats using the Output Delivery System, which was first introduced in 2007. SAS macros are pieces of code or variables that are coded once and referenced to perform repetitive tasks. PROC statements can also display results, sort data or perform other operations. There are more than 300 named procedures and each one contains a substantial body of programming and statistical work. Procedures perform analysis and reporting on data sets to produce statistics, analyses, and graphics. The PROC step consists of PROC statements that call upon named procedures. Additionally, each piece of data has a descriptor and a value. Data sets are organized into tables with rows called 'observations' and columns called 'variables'.

Afterwards, the execution phase processes each executable statement sequentially. In the compilation phase, declarative statements are processed and syntax errors are identified. The DATA step has two phases: compilation and execution. The DATA step has executable statements that result in the software taking an action, and declarative statements that provide instructions to read a data set or alter the data's appearance.

Each step consists of a series of statements. SAS programs have DATA steps, which retrieve and manipulate data, and PROC steps, which analyze the data. SAS provides a graphical point-and-click user interface for non-technical users and more through the SAS language. SAS is a software suite that can mine, alter, manage and retrieve data from a variety of sources and perform statistical analysis on it.
