8 If Developing an MDM System, then Remember You cannot depend on someone sending you your data even if that s how it has worked for 30+ years. Even though an MDMS is a data repository and can consume data easily and efficiently, that does not mean it can spit that data out easily and efficiently. 8

10 Some Milestones Decided on SmartSync and then Aclara MDM System. SmartSync installations early 2011-summer Feb. 14, 2011 Kickoff Meeting with Aclara (Load Research was there). Many Meetings followed mostly about feeding data into the MDM, interfacing CIS and sending billing parameters to CIS. October 2011 MDM Live for Billing. 3. Aug. 8, 2011 Load Research/MDM Kickoff Meeting. 4. Then what happened???? No MDM Users Instead Move Data to TeraData WH. TeraDateWH DBA began Design for Users. Late 2012 TeraData WH ready for User testing. Early 2013 Daylight Saving Time Conversion Added. 5. Early 2013 MDM to TeraData System complete almost. 10

11 Old SAS Masters. Storage Issue Increases New SAS Masters about 5Xs larger. Without Saving KVARH. 11

12 Solving the Storage Problem 1. Eliminate unnecessary variables. 2. Compress SAS data sets About 40% reduction. 3. Move files Off Line maybe FileNet. 4. Save data as text (SAS Transport File?) About 40% reduction. 5. Create and Save Summary Files delete Master files after retention period. 12

13 Remaining Issues Sporadic Overflow Issue. Virtual Meters Not Yet Included. A few accounts have multiple meters beyond simple totalization. Need a Validation/Editing Routine. About 100 meters not readable with ATT cell system but will cover with Verizon this year. 13

14 SAS Code for Sporadic Overflow 1. proc sql; 2. connect to teradata (user= tdpid='dwsprod' mode='teradata'); 3. create table I as 4. select * from connection to teradata 5. ( 6. SELECT DISTINCT 7. I.Entity_ID 8.,I.Read_Date 9.,I.Attribute_ID 10.,substr(I.meter_No,1,9) AS Meter_No 11.,substr(I.UOM_DESCRIPTION,1,5) As UOM 12.,I.Int_Value_0000 AS RKW1 13.,I.Int_Value_0015 AS RKW2 14.,I.Int_Value_0030 AS RKW ,I.Int_Value_2000 AS RKW81 18.,(CASE when I.int_value_2015 > then else I.int_value_ END) AS RKW82 22.,I.Int_Value_2030 AS RKW

16 Creating an Exception Report 1. data b; set &smast; 2. nmiss=nmiss(of rkw1-rkw96); 3. maxkw=4*max(of rkw1-rkw96); 4. minkw=4*min(of rkw1-rkw96); 5. sum= sum(of rkw1-rkw96); 6. drop rkw1-rkw96; 7. keep yrmo rate account_no mdmrate nmiss min max sum; proc means noprint; by yrmo rate account_no mdmrate; 10. output out=c 11. max(max sum nmiss)=maxkw maxkwh maxmiss 12. min(min sum)=minkw minkwh 13. sum(sum nmiss)=sumkwh nmiss 14. n=ndaysacct; 15. var nmiss max min sum; 16
