SAS TASKS
ImportSAS Enterprise Guide
Importing data from different data sources is very easy in SAS Enterprise Guide.
Capability Analyst Programmer StatisticianImport few
Pros:Easy to useFastSelf documenting
Cons:Incomplete code generatedDealing with large number of input files
ImportSAS DMS infile placeholder character ‘?’
ProsQuickComplete control
ConsCoding required
Capability Analyst Programmer StatisticianImport many Some
ImportSAS Enterprise Guide
Access DMS BASE code from EG Code node
Capability Analyst Programmer StatisticianImport many Some
ViewingSAS Enterprise Guide
ProsAutomatically displaysFilter & query builderCopy n paste rectangleRelated tasks readily accessibleDescribe data handy
ConsCannot open more than 1 x SASEG “viewtable”Explorer slow on large data, doesnot operate on WORKNo command line
Analyst Programmer Statistician
ViewingSAS DMS
ProsMany viewtable windows okCommand lineColumn & dataset attributesSort
ConsDated interfaceLimited copy and pasteWhere expression builder
Analyst Programmer Statistician
CheckingSAS Enterprise Guide
Easy to interactively check quality & distribution of values in your data.
Analyst Programmer Statistician
Easy to generate code at any time
CheckingSAS DMS
Hand code data step and PROC step code
Enhanced editor
PROC SQL, FORMAT, TABULATE, PRINT, UNIVARIATE, FREQ, MEANS, COMPARE, SGPLOT are commonly used.
Analyst Programmer StatisticianSome
CleaningStart dates need to be lined up
CleaningRainfall measures taken over days to be averaged.
CleaningSAS Enterprise Guide
Query builder or post processing filters
Comprehensive task nodes
Program task node
Combination not unusual
ProsProcess flowWhere EG tasks can be used isusually quite fastQuery builder is nice
ConsGets fiddly when changes to flowneed to be madeCopy and paste kind of worksEmbedded code needs plumbinginWhen to use tasks & when to usecode node
Analyst Programmer StatisticianSome
CleaningSAS DMS
ProsStraight at code level
ConsAt code level
Analyst Programmer StatisticianSome
Transform
Rainfall Max tempMin temp
Weather
Join
+season +station Summarise
TransformSAS Enterprise Guide
ProsJoining tables easy using QuerybuilderNew variables easily createdSummary task again easy to use
ConsUnwieldy with complex joins orexpressionsFormat builder slow – better fromdatasetsFor complex transforms likely toneed many nodes or ultimately acode node
Analyst Programmer Statistician
TransformSAS DMS
PROC FORMAT to mapPROC SQL for the join & to create variables, PROC SUMMARY or MEANS for the summary.
ProsStraight at code level
ConsAt code level
Analyst Programmer StatisticianSome
ChartSAS Enterprise Guide
ProsEasy to useFast to generateLots of customisation possible
ConsComplete customisation and useof particular PROCs eg SGPLOTrequire code
Analyst Programmer Statistician
ChartSAS DMS
ProsComprehensive customisationpossible
ConsDetailed, time consuming

ConclusionSAS DMS
Interface is dated
Continues to be functional
operates entirely at command & code level
Effective use of SAS DMS involves knowing how to code
ConclusionSAS Enterprise Guide
Easy to use, project‐oriented interface Guides users through the analytical process.
Nice FeaturesChartingSummaryRead many data sourcesEasy to useDescribe dataProject approachPlumbing
Code generation toolQuery builderProcess flowComprehensive task listIntegration with rest of SASAutocomplete (data, vars)Tooltips goes to WebCollection of tasks, code, output,log & data results
Effective use of SAS EG involves knowing when • its faster to point and click through a task or• to modify generated code or • to write code from scratch.
ConclusionSAS Enterprise Guide
SAS Enterprise Guide hasn’t completely superceded SAS DMS yet.
