how to change DB design for a change in java
This question is more of architectural level.
Suppose , we have a HTML form which has certain fields. We store these values in DB table.
In future , if the requirement arises to add 10 new fields in HTML , how do we change DB design for that .
Do we add columns in the same table?
Or do we create a new table and map it with existing table? . The requirement can be adding 50 more fields even !!
Re: how to change DB design for a change in java
That dependes, some databases don't allow it, others do but 50 fields sound like at lot to me.
Personally I would make a ObjectExtra table then
Ruby 'cause I can - Java 'cause I want - C# 'cause I have to
