SAS® software project definitions and technical requirements often fall victim to this paradox, in which rigorous quality requirements exist for data and data products yet not for the software that undergirds them.

Not surprisingly, data quality is a central focus and theme of SAS literature however, code quality is far less commonly described and too often references only the speed or efficiency with which software should execute, omitting other critical dimensions of software quality. As data analytic software, SAS transforms data into information and ultimately knowledge and data-driven decisions. Managers, customers, and other decision makers should also understand the dimensions of software quality both to define performance requirements at project outset as well as to evaluate whether those objectives were met at software completion. Without the definition and communication of performance requirements, developers risk either building software that lacks intended quality or wasting time delivering software that exceeds performance objectives-thus, either underperforming or gold-plating, both of which are undesirable.
A common fault in many software development environments is a focus on functional requirements-the what and how-to the detriment of performance requirements, which specify instead how well software should function (assessed through software execution) or how easily software should be maintained (assessed through code inspection). The text is intended to be read cover-to-cover or used as a reference tool to instruct, inspire, deliver, and evaluate software quality. The text introduces and parallels the International Organization for Standardization (ISO) software product quality model, demonstrating 15 performance requirements that represent dimensions of software quality, including: reliability, recoverability, robustness, execution efficiency (i.e., speed), efficiency, scalability, portability, security, automation, maintainability, modularity, readability, testability, stability, and reusability.

How do I get the free SAS Viewer?Įxit the NHANES Website and download the free SAS viewer.įor guidance on performing common operations, such as filtering data, saving, and copying and pasting to other applications, with the SAS Universal Viewer please see the Performing Common Tasks with SAS Universal Viewer in the SAS Universal Viewer Documentation. The Viewer provides a quick and convenient way to view SAS datasets, catalogs, transports, JMP files, HTML files, and all text-based files without invoking SAS, or even having SAS installed on your computer. The SAS Universal Viewer is a freely distributed application for viewing and printing files that were created by SAS. Datasets can be opened with the SAS viewer and saved as a CSV file that can be opened by other software applications. However, for any application that cannot read transports directly, SAS offers a free data viewer. NHANES practice is to release data as SAS transport files, which can be read directly by a number of applications. SAS software is not required to view or use NHANES data. Why is data released in SAS transport files?
