SAS for Big Data Analytics Techniques for Handling Large Datasets

In today’s world, businesses are generating vast amounts of data at an unprecedented rate. More than traditional analysis methods are required with such large amounts of data. Big data analytics is the answer to the problem. SAS, a powerful analytics tool, has been helping businesses with big data analytics for over 40 years. In this article, we will discuss how SAS can handle large datasets and its techniques for big data analytics.


SAS is a leading data management, analytics, and business intelligence software suite. It is known for its robustness, reliability, and scalability. SAS can handle large datasets, which makes it a popular choice for big data analytics. Big data is characterized by high volume, velocity, and variety of data, making traditional data analysis methods ineffective.

Handling Large Datasets with SAS

SAS can handle large datasets with ease. It is designed to handle large data volumes and is optimized for performance. Some of the techniques SAS uses for handling large datasets include:

  1. Data Compression: SAS can compress data to save storage space and reduce I/O time. Compressed data requires less disk space and can be read and written to disk faster.
  2. Data Partitioning: SAS can divide large datasets into smaller subsets or partitions. Each partition can be processed independently, reducing processing time and improving performance.
  3. In-Database Processing: SAS can run analytics directly in a database, reducing data movement and improving performance.
  4. Parallel Processing: SAS can distribute processing across multiple processors, improving performance and scalability.
  5. Data Sampling: SAS can randomly sample data from a large dataset to reduce its size, making it more manageable.

Techniques for Big Data Analytics with SAS

SAS has a range of styles for big data analytics, including:

  1. SAS Visual Analytics: SAS Visual Analytics is a powerful tool for exploring and analyzing large datasets. It allows users to create interactive dashboards, reports, and visualizations.
  2. SAS Data Mining: SAS Data Mining is a technique for discovering patterns and relationships in large datasets. It can be used for predictive modeling, segmentation, and anomaly detection.
  3. SAS Text Analytics: SAS Text Analytics is a technique for analyzing unstructured data, such as social media posts, customer feedback, and emails. It can be used for sentiment analysis, topic modeling, and text classification.
  4. SAS Machine Learning: SAS Machine Learning is a technique for building predictive models from large datasets. It includes procedures such as regression, clustering, and decision trees.



SAS is a powerful tool for big data analytics, capable of handling large datasets and using advanced techniques for data analysis. Businesses have used SAS for over 40 years and have a proven track record of reliability, scalability, and performance.
