6 reviews SAS (Statistical Analysis System) introduced the SAS Business Intelligence & Analytics Solution for large enterprises to explore their large datasets in a visually appealing format. SAS analytics is a data analytics tool that is used increasingly in Data Science, Machine learning, and Business Intelligence applications. Not only it equips the organization with all necessary tools to monitor the key BI metrics but also produces powerful analytics and comprehensive reports for its decision makers to take well-informed decisions.
