Gen EDGE

Hi all,

I am using Coolgen 8.5 with Mainframe . and I have a task to add few new attributes to an existing Entity .  I had done Data Model Changes long time ago , so need some guidance to see if I am following Right Approach

Here we go....

1.  Scoped Subset having Subject Area/Database/Entity Type in Modify Mode ,Subset Type- Design

2.   In the Toolset , I added new attributes to an Entity Type in Data Model List (Tool--> Analysis --> Data Model List)

3.   Selected ' Technical Design' as DB2  z/OS .  (Tool -->  Design --> Technical Design

4.   Clicked on Data Structure List , Implemented the attributes .

Now my questions is

1.    Am I following the right approach ?

2.  Post this activity , do I need to perform Retransformation or I can simply check-in code back to HE and then  ask  

     DBA can apply the changes to Physical Database also ?

3.  Do i need  to perform Referential Integrity or maybe not required as I haven't done any association or added any Primary Keys .

Hello Bhavik, 

I will attempt to answer your questions. If you have further questions, i would recommend that you open a support case with the Gen Support team.  

1. Am I following the right approach ?
Yes, this is a valid approach.

2. Post this activity , do I need to perform Retransformation or I can simply check-in code back to HE and then ask DBA can apply the changes to Physical Database also ?
You do not need to retransform if this attribute is not part of the identifier.  And yes, your DBA can run the DDL to implement the change to the physical database.

3. Do i need to perform Referential Integrity or maybe not required as I haven't done any association or added any Primary Keys?
See above

Thanks Steve.
