Copyright © 2004, SAS Institute Inc. All rights reserved. Forthcoming Improvements in the SAS Foundation  ODS (and the new ODS statistical graphics)  SAS Database Storage capabilities  The Data Step and Proc SQL  Grid Computing Capabilities  Bits and Pieces

Copyright © 2004, SAS Institute Inc. All rights reserved. Survival Plot Using PROC LIFETEST in SAS 8  J. Zhou, NESUG 2002  Three-page SAS program with macros  Use GPLOT and GREPLAY for graphics Statistical Metadata Overlaid Curves

Copyright © 2004, SAS Institute Inc. All rights reserved. Statistical Graphics  Essential for modern data analysis  Difficult to create in SAS prior to SAS 9 Context lost when statistical procedure terminates Programmer must recreate context, metadata  Statistical procedures should automatically create graphics  Follow the 80-20 rule – 20% of these might need further tweaking, but for the most part…

Copyright © 2004, SAS Institute Inc. All rights reserved. Usage of ODS Statistical Graphics in SAS 9  Experimental in 30 SAS/STAT and SAS/ETS procedures - SAS 9.1  Automates creation of commonly used graphical displays for a particular analysis  Production in SAS 9.2

Copyright © 2004, SAS Institute Inc. All rights reserved. Procedures Using ODS Graphics SAS/STAT Procedures  ANOVA  CORRESP  GAM  GENMOD  GLM  KDE  LIFETEST  LOESS  LOGISTIC  MI  MIXED  PHREG  PLS  PRINCOMP  PRINQUAL  REG  ROBUSTREG  TPSPLINE SAS/ETS Procedures  ARIMA  AUTOREG  ENTROPY  EXPAND  MODEL  SPECTRA  SYSLIN  TIMESERIES  UCM  VARMAX  X12 SAS High Performance Forecasting  HPF

Copyright © 2004, SAS Institute Inc. All rights reserved. ODS Graphics Primer  One statement “turns on graphics” ODS GRAPHICS ON;  Procedure options determine “which plot”  Template determines “what plot looks like” SAS provides default template for each plot  Style determines “what all my plots look like”  Destination determines “where my plots go”

Copyright © 2004, SAS Institute Inc. All rights reserved. Integration with ODS Styles  Over 30 different styles  New style elements for statistical graphics Fitted line Confidence lines and bands Prediction Lines Outliers Classification groups

Copyright © 2004, SAS Institute Inc. All rights reserved. Summary  Goal is to automate creation of graphics by statistical procedures Minimum work for user Maximum built-in functionality  Experimental in SAS 9.1  Production in SAS 9.2

Copyright © 2004, SAS Institute Inc. All rights reserved. SAS Transactional Storage (aka SAS Database Capabilities)  Demo Time  1. Color_table Remember to start your TableServer  2. Customers Remember to start your AppServer (tomcat5)

Copyright © 2004, SAS Institute Inc. All rights reserved. SAS Transactional Storage (aka SAS Database Capabilities)  A more traditional Database Capability  From SAS. (not oracle, ibm, or microsoft)  Based on OpenSource “Firebird”  Real Datatypes – INT, MONEY, VARCHAR  Real Connectors – JDBC, ODBC, SAS Libname  Real Transactions – Rollback and Commit  MultiUser Server

Copyright © 2004, SAS Institute Inc. All rights reserved. Grid Adoption is Increasing A high percentage of firms using analytical applications are considering grid 2/3 of firms surveyed are using or considering grid technology

Copyright © 2004, SAS Institute Inc. All rights reserved. Benefits of Grid Computing  Faster results  More executions – more data  Time to recover from errors  Better use of resources  Virtualize resources  Incremental IT spend

Copyright © 2004, SAS Institute Inc. All rights reserved. Types of Applications Suitable for Grid  Long running  Many replicate runs of same fundamental task simulation (what if analysis) optimization (testing lots of scenarios) BY GROUP processing data segmentation  Independent tasks running against large data sources scoring – risk analysis multiple procedures and data steps

Copyright © 2004, SAS Institute Inc. All rights reserved. SAS Grid Strategy  Infrastructure benefits SAS applications large data / complex algorithms  Focus areas Development Run-time System management  Incremental Releases

Copyright © 2004, SAS Institute Inc. All rights reserved. Analytics are working, so people…  Build more models For successively refined segments of customers  Use more data in those models  Integrate the results into operational systems  A SAS9.2 datastep moviemovie

Copyright © 2004, SAS Institute Inc. All rights reserved. Implications  More Multi thread enablement within SAS  Yes, even the DATA STEP  Saved Programs  Multi Threaded Server Capabilities Same model, parallel data for thruput Many models, same data – one off scores in operational systems  Models Management can deploy models to “score servers” without restarting them

Protect your IP  PROC SCRAMBLE file=‘myfile.sas’ outfile=‘secret.sas’ … ;  Send secret.sas to your customers  %include ‘secret.sas’; Implies nosource; your macros can reset NOMPRINT…

Copyright © 2004, SAS Institute Inc. All rights reserved. Checkpoint/Restart  Craig R.’s request as per user community  Job fails – want to restart where it left off  ETL Studio also wanted a restart facility

Copyright © 2004, SAS Institute Inc. All rights reserved. A simple solution  Record a checkpoint number, save it in WORK  If restarting, skip PROC / DATA steps to there  Tokenize everything  Execute all global statements

Copyright © 2004, SAS Institute Inc. All rights reserved. Subsequent restarting  Again use NOWORKINIT, NOWORKTERM  Again use WORK to the permanent directory  Use the RESTART option  Job will restart as of the last successful step

Copyright © 2004, SAS Institute Inc. All rights reserved. Is this what users want?  We can’t do this without user being proactive  data temp / set temp issues  skipped steps may need to be executed  Output files (flat files – DISP=MOD, databases…)

Example  Using options debug=‘checkpoint-implicit’;  Option names still to be decided

data temp1; x=1; run; data temp2; x=2; run; data temp3; x=3; run; data _null_; if "&sysparm."="1" then abort abend 999; run; data temp4; x=4; run;

Additional info  Planned for 9.2  Option names still being decided  Wanting additional input

Copyright © 2004, SAS Institute Inc. All rights reserved. Parallelization Efforts  Reading in arbitrary SAS code  Producing metadata in comments  This could be post-processed by ETL Studio  This could be post-processed by Grid Computing

Copyright © 2004, SAS Institute Inc. All rights reserved. Parallelization Efforts  Researching so far  Hooks in dependency opens  Catalogs, flat files, SAS data sets, etc.  Emitting info in comments  Example of use

Exposure to User  New option, such as DEPMETA=fileref  SAS program with comments written to this file

Copyright © 2004, SAS Institute Inc. All rights reserved. Ideas for the Future!  How can the software learn?  So the user doesn’t have to learn about the software; they can learn the business!  Some future ETL studio JOB Remembers data volumes from last weeks run Uses that memory to choose a better strategy

Copyright © 2004, SAS Institute Inc. All rights reserved. Your Turn!!  You tell me next time SAS forgets something it should have remembered  And why remembering that would help SAS improve next time Paul.Kent@sas.com Thanks for listening!
