• Re: dataset cached database

  Actually the OP said that the tables involved are small in size so scalability is NOT a problem. If the tables only contain a few hundred rows then I think cache is not needed. The solution is just simple so don't make things complicated.

• Re: Layered Architecture WorkFlow :: Business Facade - Business Layer - Business Objects - DAL?

  If I were the one designing I would remove the Facade because I think the application is simple from the way you presented it. The only use of the Facade is to encapsulate your business layer anyway so removing it will minimize "code bloat" -- but I might be wrong.

• Re: DAL Having Interfaces?

  When you are hand-coding your DAL then this is exactly the issue that you will be facing. Change something in the table and you will end up changing both stored procs and your code that's why there was a long debate years ago about stored procs vs dynamic sql or o/r mappers. Anyway, interfaces in the DAL are useful when you have different kinds of databases. For example: 1 interface IDAL { 2 void Insert(); 3 void Update(); 4 } 5 6 class SqlServerDAL : IDAL { 7 // Implementation.... 8 } 9 10 class

• Re: Connection Strings and three tier application

  When you say n-tier do you mean "physically" separating the 3 layers which is UI, BL and DAL? If that's the case then the connection string should be in the application server.

• Re: Dynamic DLL loading and performance?

  you don't need dynamic loading of assemblies for this matter. you just need to design your component well. in this case you just need to have an interface or abstract class - polymorphism. yes you can use provider pattern for this or combine it with strategy pattern.

• Re: What is the best practice for handling a collection of entities?

  Collection should ONLY be a bucket/container so making a ProductCollection is fine or you can just use List<T> for all your collections.
