SAS A00-415 Exam Topics:

Objective Details

Programming in SAS Viya Concepts (10-15%)
Describe the SAS Viya architecture. - Compute Server vs. Cloud Analytics Server (CAS)
- Serial vs parallel processing
- In-memory processing
- Open source integration
Explain when to use the CAS server for programming tasks. - Size of data
- Type of SAS procedure used

Managing Data in CAS (25-30%)
Explain how to access and use CAS Libraries (caslibs). - Establish CAS sessions with the CAS statement.
- Caslib attributes (Session, local, active, personal)
- Properties of the casuser caslib
- Use the CASLIB statement to assign session-scope caslibs
- Assign a libref to a caslib with the LIBNAME statement and CAS engine
- View the contents of a caslib with PROC CASUTIL
Describe how to load data into In-Memory Tables. - Load data files into memory
- Client-side vs server-side files
- Loading client-side data (PROC CASUTIL)
  • LOAD DATA= statement

- In-memory table scope (Session vs Global, promoting tables)
- Loading server-side data sources (PROC CASUTIL)

  • LOAD CASDATA= statement
  • ALTERTABLE statement

- Alternate data loading methods (DATA step, PROC SQL, PROC IMPORT)
Describe how to save and drop In-Memory Tables. - SASHDAT files
- PROC CASUTIL
  • SAVE statement

  • Suppressing errors
Describe CAS column data types. - Properties of character column variable types
  • CHAR
  • VARCHAR()
  • Determine when to use CHAR vs VARCHAR()

- Properties of numeric column variable types

  • DOUBLE
  • INT32
  • INT64

- Create varchar column variables with the LENGTH statement
- Determine appropriate column data types for example data

DATA Step and SQL programming in CAS (20-25%)
Explain how SAS determines where code executes. - Location of the input/output data
- What procedures are being run
- What statements/functions are used
- SESSREF= option on the DATA statement
- SESSREF= option within FedSQL
- MSGLEVEL= system option
Explain threading within the SAS DATA step. - Where code executes: CAS, Compute Server
- Effect of threads on the DATA step
- _THREADID_ and _NTHREADS_ automatic variables
- SINGLE= DATA step option
- Adjust DATA Step code when accumulating totals
- Explain how BY groups are processed in CAS enabled DATA step code
  • Relationship between the distribution of threads and BY GROUP variables
  • DATA step BY GROUP processing and sorting
Update DATA step code to run in CAS. - DESCENDING keyword
- WHERE= option
- INFILE/INPUT/DATALINES statements
- MODIFY/REMOVE/REPLACE statements
- DATALIMIT= option
- Functions not supported in CAS (Examples: RANBIN, RANUNI, SYMGET, FILEREF, GIT functions)
Update PROC SQL code to run as PROC FEDSQL code. - Data types
- Supported statements
- Mnemonics vs operators
- SESSREF= option
- Remerge
- Calculated keyword
- SET operations
- Correlated subqueries
- Dictionary tables
- Views
- LIMIT clause
- FORMAT, LABEL vs PROC CASUTIL ALTERTABLE CASDATA statement

CAS-Enabled Procedures and User Defined Formats (20%-25%)
Identify common procedures that run only on the Compute Server. - PROC FREQ and UNIVARIATE
- SG Graphics procedures
- Use the log file to identify where code executed
Use common procedures that run in both the CAS and Compute Server. - How SAS determines where the procedure runs
  • Location of the input/output data
  • Which functions/options are used in the code

- PROC MEANS & PROC SUMMARY

  • Common Supported Statements: CLASS/BY/VAR/WHERE/FORMAT
  • Common Supported Statistics: N, NMISS, MIN, MAX, RANGE, MEAN, SUM, STDERR, VAR)
  • Common Unsupported Statistics: MEDIAN, MODE, percentiles

- PROC TRANSPOSE
