Hi Shalini ,
The Transformations, Rules and Strategies tabs comprise the u201CDesign Timeu201D portion of Matching mode.
The Matches and Merge tabs on the other hand comprise the u201CRuntimeu201D portion of Matching mode.
Workflow Tab supports Matching and Merging Automation.
Terms and there Functions:
1. Normalization: When we remove the Special Characters as well as the Short forms from our data we say that the data is Normalized and this is used in Transformation technique.
2. Token: When we have to reduce the short forms they are known as Tokens.
3. Score : Score actually helps us to define the Result in the following ways:
u2022 Success :   If we find the duplicate fields it shows Success
u2022 Failure :  If we do not get any Duplicate field we say it is a Failure
u2022 Undefined :  If any of the field contains Null Value we say that it is undefined.
There are two types of Scores also:
u2022 Maximum Score
u2022 Minimum Score
Maximum Score and Minimum Score:  The read-only Min Score and Max Score properties are calculated automatically by MDM based on the Success scores of ever matching rule included in the strategy, and allow you to set the values of Low Threshold and High Threshold properties to classify the results.       
4.Difference between Equals and Token Equals:
u2022 Equals :  Exactly matches the data
u2022 Token Equals:  Fuzzy Matches are also considered.
5.Threshold: There are two categories of Threshold:
u2022 High: Records whose total score is greater than or equal to the High threshold score are included in the list of potential matches in the Matches tab and placed in the High match level.
u2022 Low: Records whose total score is greater than or equal to the Low Threshold score are included in the list of potential matches in the Matches tab and placed in the Low match level.
The Tabs along with there Functionality:
 Transformation: It basically helps us to normalize the data.
 Rules: This tab is used to define certain rules for our search i.e. what rules needs to be followed to find out the Duplicate values.
 Strategies: Strategies are the collection of Rules, we try various combinations of the rules we have already created and then try to find out the Duplicate Records.
 Matches: In this tab we can see all the entries which are found to be duplicating in our data, here we need to include all those entries which we want to merge, so that we can get cleansed data.
 Merge: Merge on the other hand is use to merge the Duplicate data into one. It has further two parts:
u2022Set:  This is used to select the data for a field of your choice among all the duplicate data that has been found.
u2022Concatenate: If we want to concatenate the two data for the same field then we use Concatenate.
Hope this would be helpful..
If helpful do reward points!!!!!!!!!!!
