Informatica PowerCenter

  1. 1. A reporter – “If I could have your phone number?” Einstein - “Certainly”. He picked up the phone directory and looked up his phone number, then wrote it on a slip of paper and handed it to the reporter. Reporter - "You are considered to be the smartest man in the world and you can't remember your own phone number?” Einstein - “Why should I memorize something when I know where to find it?”
  2. 2. HAVE FUN WITH POWERCENTER Where? This presentation was used at the end of Informatica 9.x (PowerCenter) training session conducted for new joiners in 2012 at Teradata Mumbai. Why? By the end of 2 weeks session, trainees would feel there’s too much to memorize. Even experienced professionals find hard to remember some easy stuff on finger tips.
  3. 3. • The operations that the Data Integration Service performs on the data. • Data passes through transformation ports linked in the mapping or mapplet. They generate, modify, or just pass data. • Can be active or passive. • Can be connected or unconnected to the data flow. BRUSH-UP -> TRANSFORMATION
  4. 4. Active – • Changes in the number of rows passing through the transformation. Eg - FIL • Changes in the row type. Eg – UPD • Changes in the transformation boundaries. Eg – TC • Can’t connect multiple active transformations or an active and a passive transformation to the same downstream transformation as it confuses the Data Integration Service for final o/p row count and type. Passive – • The opposite of active is passive  BRUSH-UP -> ACTIVE / PASSIVE
  5. 5. How many transformations are there? Hint : How many letters are there in English language? 26+3 transformations in version 9.1.0 Do u remember the naming convention ? XYZ_TransformationName It is useful to remember XYZ on your finger tips Are you ready for a quick recall of their names & usage? While a name pops-up on the next screen, you should be able to recollect the full name and usage of the transformation 29 TRANSFORMATIONS – QUICK RECALL
  6. 6. TOTAL (29) RECALL - NAME & USAGE TC SQ SEQ RTR RNK OUP NRM LKP JNR JTX INP HTTP FIL EXT EXP Web services consumerData_Masking ASQ CT AGG XSQ XP XG UPD UDT UN SPSQL SRT
  7. 7. • There are a couple of rules you need to follow. • The tip to pass the questionnaire is to not to think beyond rules. • To be back to the rules, you can press the “Brush up” button on the bottom right corner anytime. • Have a note of the slides if you see Einstein on the top- right corner. Refer to the notes alone while answering the questionnaire. • By the end you’ll have a short note ready for your anytime anywhere quiz or an Informatica interview  READY FOR A QUESTIONNAIRE?
  8. 8. ‘P’ in “name” (not in prefix “XYZ”) is for Passive RULE OF PASSIVE EXCEPTIONS OF PASSIVE 5 ARE ACTIVE & PASSIVE BOTH UPD, XP are Active SEQ and Data_Masking are Passive (with P) LKP (without P) CT, JTX, SQL, UDT TIP : 1. LISTEN TO THE QUESTION CAREFULLY CONCENTRATING ON TRANSFORMATION NAME ALONE 2. READ THE SLIDE AGAIN REPLACING FULL NAMES OF TRANSFORMATIONS IN PLACE OF XYZ
  9. 9. RULE OF PASSIVE APPLICABLE ON FULL NAMES While reading the full name aloud, guess it’s active/passive? Don’t bother to apply exceptions for now. AGG ASQ CT Data_Masking EXP EXT – External Procedure FIL HTTP INP JTX - Java JNR LKP NRM OUP RNK RTR SEQ SP SQ SQL SRT TC UN UDT UPD XP XG XSQ Web services consumer
  10. 10. EXCEPTIONS Guess which are either exception to “P” rule or are both Active & Passive? Hint : 5 are both active and passive. Move them aside first. Rest are opposite of “P” rule. CT Data_Masking JTX LKP SEQ SQL UTD UPD XP
  11. 11. • If you are really engrossed in this presentation, you might have not noticed asymmetry in slide appearance and font type or color  • There’s no welcome slide either. • Not even there’s an agenda to scare about what’s coming next? • Furthermore you might not notice asymmetry in the contents ahead  • Einstein might have not made note of some of the slides and you might not see him going forth. A FEW MORE TIPS
  12. 12. NO TRANSFORMATION IS UNCONNECTED ALONE 3 ARE UNCONNECTED & CONNECTED BOTH - LKP SP EXT – External Procedure
  13. 13. EXECUTE UNCONNECTED When unconnected data flow gets executed? Pre/Post of – Read Source Write Target
  14. 14. MULTI-GROUP TIP: VISUALIZE THEIR USAGE TO RECALL WHY ARE THEY MULTI-GROUP CT HTTP JNR RTR UN XG XP XSQ XT
  15. 15. EXPRESSION EDITORS ARE AVAILABLE IN? TIP: VISUALIZE WHERE YOU’VE EVER EDITED LOGIC? AGG EXP FIL RTR TC UPD
  16. 16. COMMENT IN EXPRESSION EDITORS TWICE HYPHEN OR FORWARD SLASH -- //
  17. 17. RETAIN PREVIOUS RECORD’S VALUE VARIABLE PORT USAGE 1st <- 2nd <- i/p | o/p i.e. Input_port Variable_port_1= Variable_port_2 Variable_port_2= Input_port Output_port = Variable_port_1
  18. 18. Dear Viewer! I appreciate your time and patience. May be we could make it better together. Please feel free to reach out to me any moment – nidhikadam@yahoo.co.in BETTER IDEAS?
