3Purpose of Transformation in DQM? Staging->Exact and Cleanse are common transformations given by Oracle [Pre-Seeded]->You can define as many custom transformation rules, like replacing Z with S->Multiple transformation rules can be applied to each column. For each transformation applied, a independent column value is stored in staging tableFirst NameAnilLast NamePassi’anPASSIANPSNExactCleanseANILExactANLCleanseEXACT TRANSFORMATION Make all characters UPPER case Remove non-alphanumeric characters Replace multiple white spaces by single white space CLEANSE – All above rules of EXACT plus Remove double lettersRemove all vowels, except leading vowelsMatch FoundTransformation can be applied again to values that user is searching. Lets say user searches on Aneeal Passion->These transformations can differ from those used for staging. But most likely we use same transformations when searching as that for staging.While doing DQM config, we will give Higher Scoring to Last Name, and lower Scoring for First Name matchAneealFirst NamePassionLast NameANEEALANLPASSIONPSNExactCleanseFor Last Name, we give 100% Weighting to EXACT Match, and say 65% weight to CLEANSE. Hence match based on Exact will have higher rankUser searches for Aneeal Passion….eeeks
4To setup DQM for Staging:- Decide the columns that you would like to search & score/rank upon. For example Last Name, First Name, DOB, NI Number etcDefine custom attributes for those columns that are not held within TCA table like HZ_PARTIES. For example NI Number is not in TCA tables, hence we can define Custom Attributes for NI Number, and then define Custom Procedure that returns NI number from HR tables [for a given party_id]Define the transformations for each column. Multiple transformations can be definedMake a transformation active to allow it being used for scoring or “data search”If Acquisition Flag is checked, it means this transformed value will be used for searching initial set of matching records.If Acquisition Flag is NOT checked, it means this transformed value will be used solely for the purpose of Scoring the records returned by acquisition phase.Multiple transformations can be applied to each column.
5Define match rules http://oracle.anipassi.com Scoring happens after Filtration and Acquisition has been done. The resultant set of records are then run through scoring process, so that we can display highest ranked matches on the top of listThese are the transformations which will be used for performing search.Only those Transformations that have their “Acquisition Checkbox Flag” checked [in previous slide], can be used in acquisition phaseA custom attribute can be defined to Filter out invalid Party Records. Filter is applicable if we can programmatically suppress duplicate/invalid Party records from appearing.
6Scoring Phase [After Acquisition phase is completed] Assign score to each column. Match found on Party Number will have Score 100, whereas match on Last Name can be score of 90. Score for match on Title[Mr/Ms] will be still lowerWithin each column, each transformation can be given different Weight. EXACT match can be given 100% weight, whereas CLEANSE [after removing vowels] will be give lower weight.Transformations used in Acquisition can be used for Scoring too.
