Defining datasources in Application Vs App Server



Defining datasources in Application

  • Pros
    • Avoid configuring client's application server  
    • Useful in development stage to just change the parameters and build and deploy 
  • Cons
    • Cannot use same build for Dev, QA, UAT and Pro. that may leads to minor problems 
Defining datasources in App server

  • Pros
    • More secure by having it in app server configuration builder will not have the credentials to the clients DB 
    • Can make war file smaller having DB modules in app server
    • Can use same war file in multiple places (Test, Production and different clients) 
    • Can use same build for staging and make sure that application works perfectly 
    • Easy deployment 
  • Cons
    • Based on the different clients having different application servers would take some time to configure

This will save us both time and resources. When to use? and Why? Creating new objects by cloning other objects. Allows for adding any subclass instance of a known super class at run-time when there are numerous potential classes that you want to only use if needed at run-time. Reduce the need for creating sub classes public interface Shape extends Cloneable {            public Shape makeCopy(); } public class Circle implements Shape {            public Circle() {                 ...
