The SAS® Certified Specialist in SAS Viya exam is designed for programmers who are ready to demonstrate their ability to work with SAS programs in a Viya environment. In this environment, data is stored in memory (CAS - Cloud Analytic Services) and processes are distributed across multiple machines, allowing for faster and more efficient analysis. Successful candidates will show proficiency in working with CAS tables, modifying traditional SAS programs to run in a distributed CAS environment, and utilizing SAS Viya’s powerful tools to handle large data sets efficiently.
One of the foundational skills tested in this certification is working with CAS tables and data sources. In SAS Viya, data is stored in the CAS engine, and it is critical for candidates to know how to load, manage, and manipulate CAS tables effectively. Working with these tables is different from traditional SAS datasets, as the data is stored in-memory and is distributed across multiple nodes for parallel processing. Understanding how to load data into CAS, access the data, and perform basic operations is essential for any SAS programmer working in this environment.
Candidates will also need to modify their traditional DATA step and SQL programs to run in the CAS environment. Since data processing in Viya is done in a distributed fashion, understanding how to adjust DATA step and SQL code to run within the CAS engine is key. This includes using CAS-enabled procedures that are optimized for distributed computing, allowing analysts to process large datasets efficiently. Knowing how to use these specialized procedures and make your SAS code compatible with the CAS engine will be a critical aspect of the certification.
Another important skill is the ability to use user-defined formats in CAS. Formats are crucial for controlling how data is presented in reports or analyses, and being able to use them in a distributed CAS environment ensures that the data is displayed consistently across all users. Candidates will need to understand how to define, manage, and apply user-defined formats within CAS, a skill that directly impacts the quality of reporting and data analysis.
In conclusion, the SAS Certified Specialist in SAS Viya exam is ideal for SAS programmers looking to prove their expertise in working with CAS tables and leveraging the full potential of SAS Viya for in-memory, distributed data processing. Mastery of key skills such as modifying traditional SAS programs to run in CAS, using CAS-enabled procedures, and applying user-defined formats will ensure that candidates are well-prepared to handle large-scale data processing and analytics in the Viya environment. This certification is a valuable credential for SAS programmers aiming to advance their careers and expertise in modern analytics technologies.
