What a waste of disk space!  Storing spaces instead of leaving a column null?  Sounds like storing a bunch of useless garbage to me.

Hi all,

We have an outside vendor developing an application, which we will ultimately inherit for maintenance.  They are porting this application from a different database platform to Oracle, since we are an Oracle shop.  They have decided to make every column in every table a NOT NULL column.  They want to implement default values at the database level for every column (' ', 0 and some low date for varchar2, number and date) and then let the application validate and enforce significant data as required.  I am looking for opinions on the pros and cons of this type of approach, both from a database and application point of view.

Thanks,

Siv
