Table inheritance process

Table: TableA

First set property Table Inheritance = YES

Then create a Int64 type field : InstanceRelationType setThen set property InstanceRelationType = InstanceRelationType

Then added new fields : StudentID, Name

Table A properties:

Table : Table A

Then create records

*** Here InstanceRelationType hold the TableID of Table A = 103696

Table: Table B

Then set properties:

Note : I noticed that if i set Abstract = YES then its not allow me to create a New Record.

So, i put Abstract = No

Then add new fields in Table B

It will automatically create relation with Table A with RecID.

Then create a new record in Table B

Then I browse Table A

It’s showing last 2 records from Table B which I am creating in Table B.

103697 is table id of Table B. 

**** Kindly Validate above process are correct ?

I have queries :

1. What is tthe use of Table A records ?

2. Why Table A records are not showing in Table B ? Because i extend Table A in to Table B.

3. What is the advantage of here Table Inheritance ?

Please give me more shed on this.

Thanks!
