Statistical Analysis System


The SAS, or Statistical Analysis System, is a collection of software products that is grouped and offered by the SAS Institute which is widely used for Decision Making and Predictive Analysis.SAS is the technology which was compliance by 21 CFR Part 11 and is widely used by many Pharmaceuticals, Biotechnology, Medical Device and Neutraceutical Clients Globally. SAS is a technology which is primarily used for Management of Data, Data Analysis and Report Generation. Many businesses and individuals need to analyze data in order to make better decisions. As businesses become more complex, there is more information and it needs to be examined. Sometimes students must do research projects where they need to collect information in order to analyze it. The amount of data is increasing daily. A newer development is the Internet and e-commerce. Companies that do business on-line want to collect information to see what type of people use their web site. They can also look at how people use their Web site in order to design their information easier. They also have to provide round the clock service. They need software to help them analyze their data. In 1976, The SAS Institute Inc., a privately held corporation was formed. The product at that time was known as the "Statistical Analysis System." It grew in popularity and capability and was used in academic groups. These people needed a software package that would do statistical calculations easily. They were not necessarily programmers. SAS can be used without knowing much about programming but it is also a very sophisticated language and more can be done with it. It has grown into the world's largest privately held software company. Continual product line expansion and diversification of clientele have resulted in SAS products being used by over 40,000 customer sites in 50 countries. There are 3.5 million users of SAS products. Part of the reason for the continual growth is that the SAS Institute works with the end user to improve its product. It offers solutions for data warehousing, data mining, data visualization, and applications development. SAS now stands for the SAS System. SAS is located in Cary, North Carolina. It is a world-wide company with business in Asia, Pacific and Latin America, Europe, Middle East and Africa. SAS also has a good employee retention rate of 96%. It also is a family oriented company and is friendly to working women. The SAS System is an applications system that can be used as 1). a statistical package, 2). a data base management system and 3). a high level programming language. When people want some kind of information, they usually start with an application for data. An applications system is software that gives you the tools you need to make the data useful and meaningful. In order to be useful, an applications system should give you 1). total control of your data, 2). facilitate applications that run in more than one computing environment, and 3). accommodate varying skill levels of potential users. SAS is also portable across computing environments. A computing environment is determined by the HARDWARE and the host OPERATING SYSTEM running it. SAS can be used on IBM mainframes, UNIX based machines, on personal computers using Windows. SAS is a powerful programming language which has a collection of ready-to-use programs called procedures. It can give an unlimited variety of applications--from general purpose data processing to highly specialized analysis in diverse applications areas.
