This is a general question, not specific to my current application.

In a heavy Traffic MultiThreaded application, what is the approach to do following: assume that there is a DAO which contains a method updateData to update some data inside of a database.

Questions:

  1. Is it a good approach to have a Singleton instance of that DAO class and access it’s method updateData?
  2. Or should I every time create a new object of that DAO and call the method updateData?

    I would have marked such DAOs as Spring beans
