Field Types

Field Types

Below are descriptions of the fields supported by the various Match Purposes, provided in alphabetical order.
Field
Description
Address_Part1
Typically includes that part of address up to, but not including, the locality "last line". The word order, i.e. the position of the address components, should be the normal word order used in your data population. These should be passed in one field. Depending on table design, your application may need to concatenate these attributes into one field before calling SSA-NAME3. For example, in the US, a typical string to pass would comprise of:
Care-of + Building Name + Street Number + Street Name + Street Type + Apartment Details
Matching on
Address_Part1
uses methods and options designed specifically for addresses. It has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
It is also possible to supply the entire address in the
Address_Part1
field for matching.
The application may pass multiple addresses (such as a residential address and a postal address) in the one call to SSA-NAME3. Refer to the
API REFERENCE
manual for more details.
See the
Key Fields
section for more details on
Address_Part1
.
Address_Part2
Typically includes the "locality" line in an address. For example, in the US, a typical string to pass would comprise of:
City + State + Zip (+ Country)
Matching on
Address_Part2
uses methods and options designed specifically for addresses. It uses the same Edit-List as
Address_Part1
. The rules in this Edit-List can be overridden by the Population Override Manager or Edit RuleWizard.
Attribute1, Attribute2
Attribute 1 and Attribute 2 are two general purpose fields. They are matched using a general purpose string matching algorithm that compensates for transpositions and missing characters or digits.
Date
The
Date
field is used for matching any type of date (e.g. date of birth, expiry date, date of contract, date of change, creation date, etc).
It expects the date to be passed in
Day+Month+Year
order. It supports the use or absence of delimiters between the date components.
Matching on dates uses methods and options designed specifically for dates. It overcomes the typical error and variation found in this data type.
ID
The ID field is used for matching any type of ID number (e.g. Account number, Customer number, Credit Card number, Drivers License number, Passport, Policy number, SSN or other identity code, VIN, etc).
It uses a string matching algorithm that compensates for transpositions and missing characters or digits. It also has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
Organization_Name
Used to match the names of organizations. These could be company names, business names, institution names, department names, agency names, trading names, etc.
This field supports matching on a single name, or a compound name (such as a legal name and its trading style). It has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
The application may also pass multiple names (e.g. a legal name and a trading style) in the one call to SSA-NAME3. Refer to the
API REFERENCE
manual for more details.
See the
Key Fields
section for more details on
Organization_Name
.
Person_Name
Used to match the names of people. An application should pass the full person name. The word order, i.e. the position of the first name, middle names and family names, should be the normal word order used in your data population. For example, in English speaking countries, the normal word order would be:
First Name + Middle Name(s) + Family Name(s)
Depending on table design, your application may have to concatenate these separate fields into one field before calling SSA-NAME3.
This field supports matching on a single name, or an account name (such as JOHN & MARY SMITH).
The application may also pass multiple names (e.g. a married name and a former name) in the one call to SSA-NAME3. Refer to the
API REFERENCE
manual for more details.
It has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
See the
Key Fields
section for more details on
Person_Name
.
Postal_Area
The
Postal_Area
field can be used to place more emphasis on the postal code than if it were included in the
Address_Part2
field. It is used for all types of postal codes, including Zip codes.
It uses a string matching algorithm that compensates for transpositions and missing characters or digits. It also has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
Telephone_Number
The
Telephone_Number
field is used to match telephone numbers.
It uses a string matching algorithm that compensates for transpositions and missing digits or area codes. It also has its own Edit-List whose rules can be overridden by the Population Override Manager or Edit RuleWizard.
