Hi,

Two different data elements referring to same domain is called two level domain concept!!

Hi,

There is Two-Level Domain Concept.

which means the Technical specifications like Data Type and Length are specified by Domains.

and the Functional Specifications are given by the Data Element which refer to the Domain.

More than 1 Data Element can refer to a Single domain.

this is called as Two Level domain Concept.

Hi,

If a domain is used for two different data elements, then it is called as Double level domain.

Hey Fren,

In the DDIC we have a concept called as dual-level domain.

Let us have an example to get it cleared...

Imagine you need to create Transparent Table with the following fields....

01. Booking_ID

02. Name_of_Person

03. Arrival_Time

04. Arrival_Date

05. Departure_Date

06. Departure_Time

07. Country_From

08. City_From

09. Country_to

10. City_To

11. Price

Now, in this case you need to create 11 domains if there was not a dual-level concept..

But the dual-level concept helps us in having a better maintainability.

In the above example,

|i--------Fields -------|-----DataElements-----|-----Domains-------i| 
|i-----------------------------------------------------------------i|
| Arrival_Time         |      ZTime_1    }_______>  Z_Time   
| Departure_Time       |      ZTime_2    }                          
|--------------------------------------------------------------------|             
| Arrival_Date          |      Zdate_1     }_______>  Z_Date  
| Departure_Date       |      Zdate_2     }                         
|--------------------------------------------------------------------|
| Country_From        |      ZCountry_1 }_______> Z_Country   
| Country_To           |      ZCountry_2 }                          
|--------------------------------------------------------------------|
| City_From            |     ZCity_1       }_______> Z_City      
| City_To              |     ZCity_2       }                            
|--------------------------------------------------------------------|
| Price              |    ZPrice          }----->  ZPrice

The Fields having Similar Technical Attributes are associated to the same Domain but due to the different Semantic Meaning the Fields are Associated with different Data Elements...

Thus it helps us in Maintaining the Data Elements Centrally ....i.e at the Domain level.....

Hence Dual-Level Domain Concept........

To have some more Information on Domains,
