Technical overview and terminology

SAS is a software suite that can mine, alter, manage and retrieve data from a variety of sources and perform statistical analysis on it.[3] SAS provides a graphical point-and-click user interface for non-technical users and more through the SAS language.[3]

SAS programs have DATA steps, which retrieve and manipulate data, PROC (procedures) which analyze the data, and may also have functions.[4] Each step consists of a series of statements.[5]

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.[4] The DATA step has two phases: compilation and execution. In the compilation phase, declarative statements are processed and syntax errors are identified. Afterwards, the execution phase processes each executable statement sequentially.[6] Data sets are organized into tables with rows called "observations" and columns called "variables". Additionally, each piece of data has a descriptor and a value.[4][7]

PROC statements call upon named procedures. Procedures perform analysis and reporting on data sets to produce statistics, analyses, and graphics. There are more than 300 named procedures and each one performs a substantial body of statistical work.[4] PROC statements can also display results, sort data or perform other operations.[5]

SAS macros are pieces of code or variables that are coded once and referenced to perform repetitive tasks.[8]

SAS data can be published in HTML, PDF, Excel, RTF and other formats using the Output Delivery System, which was first introduced in 2007.[9] SAS Enterprise Guide is SAS's point-and-click interface. It generates code to manipulate data or perform analysis without use of the SAS programming language.[10]

The SAS software suite has more than 200 add-on packages, sometimes called components[11][12][13] Some of these SAS components, i.e. add on packages to Base SAS include:[3] [14]

  • Base SAS – Basic procedures and data management
  • SAS/STAT – Statistical analysis
  • SAS/GRAPH – Graphics and presentation
  • SAS/OR – Operations research
  • SAS/ETS – Econometrics and Time Series Analysis
  • SAS/IML – Interactive matrix language
  • SAS/AF – Applications facility
  • SAS/QC – Quality control
  • SAS/INSIGHT – Data mining
  • SAS/PH – Clinical trial analysis
  • Enterprise Miner – data mining
  • Enterprise Guide – GUI based code editor & project manager
  • SAS EBI – Suite of Business Intelligence Applications
  • SAS Grid Manager – Manager of SAS grid computing environment
  • SAS CI360 - Customer Intelligence

Software products

As of 2011, SAS's largest set of products is its line for customer intelligence. Numerous SAS modules for web, social media and marketing analytics may be used to profile customers and prospects, predict their behaviors and manage and optimize communications.[15]

SAS also provides the SAS Fraud Framework. The framework's primary functionality is to monitor transactions across different applications, networks and partners and use analytics to identify anomalies that are indicative of fraud.[16][17][18]

SAS Enterprise GRC (Governance, Risk and Compliance) provides risk modeling, scenario analysis, and other functions[19][20] in order to manage and visualize risk, compliance and corporate policies. There is also a SAS Enterprise Risk Management product-set designed primarily for banks and financial services organizations.[21]

SAS products for monitoring and managing the operations of IT systems are collectively referred to as SAS IT Management Solutions.[22] SAS collects data from various IT assets on performance and utilization, then creates reports and analyses.[23] SAS's Performance Management products consolidate and provide graphical displays for key performance indicators (KPIs) at the employee, department and organizational level.[24][25]

The SAS Supply Chain Intelligence product suite is offered for supply chain needs, such as forecasting product demand, managing distribution and inventory and optimizing pricing.[26] There is also a "SAS for Sustainability Management" set of software to forecast environmental, social and economic effects and identify causal relationships between operations and their impact on the environment or ecosystem.[27]

SAS has products for specific industries, such as government, retail, telecommunications, aerospace, marketing optimization, and high-performance computing.[28]
