This week's book giveaway is in the Reactive Progamming forum. We're giving away four copies of Reactive Streams in Java: Concurrency with RxJava, Reactor, and Akka Streams and have Adam Davis on-line! See this thread for details.
I heard a technical scenario where 2 entities having same attributes. A Boy and Girl Entity with Name, Age and DOB. How this can be formed as single entity so that fields are not repetitive ? Please share any idea. I'm also keen to find the right solution through studies. But your ideas may also help. Thanks.

Stephan, by your idea what I understand is change to the db design of table structure itself. Instead having two tables (Boy and Girl) have one table with the name PERSON with attributes(NAME, AGE, DOB, GENDER(ENUM)) and represent the above Person table as a single Entity. Am I on track to get the above ?
Thanks & Regards.
Today is the first day of the rest of your life.

Yes, although I don't know why you would want to have an age field if you already have a date of birth field.
