1 ACHOO - THE FLU, SAS & YOU CHARU SHANKAR, SAS INSTITUTE CANADA Health User Group Toronto 20 November 2015

2 AGENDA ACHOO - THE FLU, SAS & YOU 1. Some like it cold -Ways to fight the flu 2. Data Collection 3. Data Analysis a new tool in time for the holidays. DS2 4. Data Management SAS Enterprise guide to prompt you. 5. Data Presentation Get visual with a map 6. Handy Resources 7. Q & A

3 WAYS TO FIGHT THE FLU WHAT DO I DO? Diet Oil Pulling Yoga inversions Medication - Ginger lozenges And THEN Educate myself..get SAS Help

4 DATA COLLECTION ACHOO - THE FLU, SAS & YOU

5 DATA ANALYSIS HOW ABOUT A NEW TOOL? DS2

6 DATA ANALYSIS DS2 OVERVIEW

7 1. OBJECT BASED SYNTAX- USER DEFINED METHODS AND PACKAGES PROC DS2; data _null_; method c2f(double Tc) returns double; /* Celsius to Farenheit */ Define method return (((Tc*9)/5)+32); end; method init(); dcl double Degc DegF; do DegC=0 to 30 by 15; DegF=c2f(DegC); PUT DegC= DegF=; end; Call method end; enddata; run; quit;

8 DS2 OVERVIEW 2. ANSI SQL DATA TYPE SUPPORT EXTENDED DATA TYPES The syntax of the DS2 language intersects with the SAS DATA step but also includes additional data types, ANSI SQL types, programming structure elements, and userdefined methods and packages BIGINT BINARY(n) CHAR(n) DATE DOUBLE FLOAT(p) INTEGER NCHAR(n) NVARCHAR(n) REAL SMALLINT TIME(p) TIMESTAMP(p) TINYINT VARBINARY(n) VARCHAR(n)

9 DS2 Complements the DATA Step DS2 has DATA and SET statements IF..THEN..ELSE, DO loops Expressions and Functions Future: Debugger DS2 does not have INFILE and INPUT statement MERGE, UPDATE MODIFY / REPLACE POINT= DS2 IS NOT A DATA STEP REPLACEMENT

10 PROC DS2; data _null_; method init(); dcl varchar(20) foo; foo = '**> Starting'; put foo; end; method run(); set ds2_sas.banks; put _all_; end; method term(); dcl char(11) bar; bar = '**> I quit!'; put bar; end; run; quit; BASIC DS2 SYNTAX Initial processing Execution loop Final processing

11 proc ds2; data sales (overwrite=yes); keep Customer_ID Total; method run(); set {select c.customer_id,total_retail_price from ds2_sas.order_fact f full join ds2_sas.customer_dim c on f.customer_id=c.customer_id order by 1}; by customer_id; if first.customer_id then Total=0; Total+total_retail_price; if last.customer_id then output; end; enddata; run;quit; 3. EMBEDDED SQL IN DS2 Returns SQL result set as input stream BY group processing on results

12 DS2 WHY USE IT? You will see the most benefit from DS2 1. When you need to use extended data types to maintain consistency with source database 2. Where you have a complex process that could benefit from structured code. You can make use of packages and methods to re-use common functions or operations. 3. Where you have computationally intense processes which can utilize parallel processing.

13 DATA ANALYSIS HOW ABOUT A NEW TOOL? DS2 DS2 DEMO

14 DATA MANAGEMENT PROMPTS IN SAS ENTERPRISE GUIDE DO YOU LIKE TO BE PROMPTED?

15 DATA PRESENTATION GET VISUAL WITH A MAP

16 HANDY RESOURCES LINKS & TRAINING Next dates for DS Dec 2015 SAS Canada DS2 training SQL within SET Statement Which Canadians get the Flu Using Arrays in SAS Programming I object: SAS Does Objects with DS2 Map code
