• Re: Relationship between Domain Model, BLL and DTOs

  Pardon me if I misunderstood you, but even if you do not have DTOs, you will have the same issue because you will need to create different methods to save/update your record based on what the user has entered. For example: to save a normal user (or update the record) you will need to have a different method and a different SP which just updates a certain set of fields. For the Admin user, you need to update all fields. Now this can obviously be implemented easily, but might create problems in exposing

• Re: Performance issues

  [quote user="Anandkbs"]1. In my second layer am passing two arrays of parameters and the values.[/quote] Why do you want to use Arrays? Try to see if you can use Dictionary/HybridDictionary etc.

• Re: Forum Groups / Board ID

  Both options can work, but I would go for the second option: create another table for Groups and use GroupID as a FK in the forums table. This would help me in keeping my data normalized as well as simple to understand.

• Re: Difference B/W MVC Architecture and 3-Tier Architecture

  No, MVC is a design pattern, and layering/tiering is related to architectural aspects of your application. You can easily create an n-tier application which has MVC in the GUI. So its like: GUI (MVC) BL DAL //other tiers

• Re: Relationship between Domain Model, BLL and DTOs

  Yes, BL should encapsulate business logic (methods/operations) and you may want to keep DTOs in a separate layer/class library and use them within BL as well as DAL.

• Re: Relationship between Domain Model, BLL and DTOs

  Hi, I would re-factor your code to something like: public class Order { private OrderDTO _orderDTO; public int OrderNumber { get { return _orderDTO.OrderNumber;} set { _orderDTO.OrderNumber=value} } //other properties go here } So your BL class is using the DTOs internally and hence becomes a part of the domain model.

• Re: Sharing a SqlConnection

  [quote user="MikeJ83"] I would like to share this connection between event handlers, so I am not closing and re-opening the connection.[/quote] I recommned that you should close/dispose your connection by enclosing it in the "using" statement and let the SQL server connection pool handle the pooling mechanism. Passing open connection arounds is not only buggy but might affect performance too. It is best to let the SQL Server pool manage the pooled connections. If you do not call

• Re: Anyone built a sales commissions app?

  Hi, In such cases, one of the options is to use a lot of "meta-data" tables, like adding info for sales duration in months or quarters. You will need to create tables like: 1. Sales_Bonus (Duration (int, FK), BonusAmount(float)) 2. Sales_DurationCycle (Duration (PK), DurationType (1=monthly, 2=quarterly) etc. Once all such tables with meta information are created, you just need to apply your conditional logic after getting values from these tables. HTH, Vivek

• Re: Abstract Class

  If your return types show similar behavior, then you can encapsulate them inside another abstract class (or an interface) and then use runtime polymorphism so that all method signatures have the same parent return type, like: public abstract class A { //some methods } public class B : A { //concrete class implementing A } public class C : A { //concrete class implementing A } Now your main class can have methods like: public abstract Collection<A> Load(); This can return collections for both
