Programmatic definition of data sets

Is it possible to programmatic define data sets?

Something like in jdbdt http://jdbdt.org/DataSets.html

DataSet data = 
   builder(t)
  .sequence("ID", 1) // 1, 2, 3, ...
  .sequence("LOGIN", "harry", "mark", "john")
  .sequence("NAME", "Harry H", "Mark M", "John J")
  .sequence("PASSWORD", i -> "password " + i , 1)
  .random("CREATED", Date.valueOf("2015-01-01"), Date.valueOf("2015-12-31"))
  .generate(3) // generate 3 rows 
  .sequence("LOGIN", i -> "guest_" + i, 4)  // "user_4", "user_5", ...
  .sequence("NAME", i -> "Guest User " + i, 4) // "Guest User 4", ...
  .value("password", "samePasswordForAllGuests") 
  .generate(6) // 6 more rows keeping ID sequence and CREATED random filler
  .data();   

This will improve refactoring in case of database schema changes, also generation can be simplified.

Hey folks, anything else we should consider before merging the PR?

I would like to thank you for all the ideias and your time discussing the DataSetBuilder API and reviewing the PR in details.

On the first moment I don’t even consider It would be a good ideia to add such builder but now, thanks to you all, I’m not just certain but am sure that the DataSetBuilder can bring a lot more users to our API, so again thank you very much!
