using design patterns for software development

Yes, why not. But first you need to clarify what do you mean to say by Design pattern? You have not specified anything related to the "Design". 

 

If you wanted to share the views about database, then you should have meant or mentioned the database design approach. Otherwise, the software development pattern.  In that question, database was mentioned and also a Singleton pattern for objects in the application. You should know that both concepts are different. Singleton pattern allows you to have only one instance of object in the application, thus preventing you from having another object instance. 

 

You can use this if you want to use only one instance of object... Objects are database instances, connection strings and other pool-based connections. What were you looking for? Clarify it, so that we can solve the riddle. :-) 

actually not for design interface. I came to know that we can use design pattern for connection string but I do not know how to use. I searched in net and found that when we have multiple database we can use design pattern to select for the database. Is this is one of the case.

also I found one link :: http://stackoverflow.com/questions/814206/getting-db-connection-through-singleton-class 

Please guide me I need to learn. thank you for your quick response.

Hello, 

 

Instead of design... You should use programming models and architecture patterns. Beginners have problems understanding the software development patterns, and other similar stuff. Because they are either too complicated into technical grammar or either the beginner doesn't have enough time. 

 

Somehow, there is a framework (pattern) that I believe would be much easier for you to learn and build your applications over; MVC. It stands for, 

 

1. Model
2. View
3. Controller

MVC is a competing pattern for software development purposes. You can use it. If you want to learn it, here is an article of mine which would assist you.
