Architecture :: Data Access Layer And Business Logic Layer?

Jun 24, 2010

I am building a web site following the tutorials on asp.net. I am using dataset as data access lay, and writing classes to access the dataset. But the example is just basic ideas, how do I retrieve individual table column value in the business layer?For example, if I have a table called Product, I only want to find out what is the product name by product id. I did this in my ProductBLL:

public ProductBLL
{
public int GetProductName(string productId)
{
ProductDataSet.ProductDataTable prodData = Adapter.GetProductById(productId);
[code]...

Is there a better way, or am I doing this correctly? Can anybody give me a reference to a more complicated business logic model?

MVC :: How To Make Business Layer Seperate From Presentation Layer

Feb 23, 2011

I've even got my JQuery Ajax submission going on now but I've encountered another problem. I *think* it's something to do with the structure I'm using but like I say, I'm fairly newo this.I have my AJAX form submission which builds my "PersonViewModel" (model for the presentation layer) in JSON and sends it to "@Url.Action("RegisterSubmit")" in my Person Controller. Now, I seperate my business layer from my View/presentation layer so in "RegisterSubmit"I'm verifying the model is valid then instantiating a new instance of my business model "Person", adding the values from "PersonViewModel" and then calling my "Save" function.

Business Layer Errors And Service Layer Handling?

Mar 7, 2011

We're building a large web app that has numerous layers. In order to communicate to the business layer we're using a service layer that the web layer calls when data is needed. Unfortunately, it seems that if exceptions are thrown in the business layer, it seems that the services on the web side are wrapping the exceptions and re-throwing them. We're looking for a clear way to encapsulate the error and log it, without WCF wrapping a new exception around the original.

MVC :: Custom Ex Class Be In The Repository Layer Or The Domain Layer?

May 6, 2010

My repositories throw exceptions (System.Exception) when some things go bad and I know this is bad practice.. so i will create a custom exception (DataException). My question is should this custom ex class be in the repository layer or the domain layer? Im thinking it should be in Domain layer where all business objects and repository interfaces live but just want to make sure.

C# - N-layer Business/service Layer Design?

Jan 26, 2011

I'm trying to reevaluate our n-layer architecture and would love to get some based on your experiences. Here is our typical .NET n-layer (sometimes n-tier) design.

Project.UI
Project.Services
Project.Business
Project.Model
Project.DataAccess

DataAccess typically consists of Entity Framework 4 and Repository classes. I attempt to follow the Aggregate Root concept in order to avoid having a repository for table, easier said than done in my experience. I tend to have ~70% match between Repositories and Tables.

Model usually consists of my Entity Framework 4 entities, I've been using Self-Tracking EF entities with success.

Business is what I struggle with the most. I typically have a Manager class for every Repository. This class will contain methods like .Add() which will perform business validation before forwarding down to repository.Add().

Services, typically I will only implement this if in fact I am looking to create a web service based solution. This layer will be tasked with marshaling requests/responses between DTOs and entities. And most importantly provide the more coarse grained interface. For example a TradingService.SubmitTrade(), which is really a facade for a business transaction which might include AccountManager.ValidateCash(), OrderManager.SubmitOrder(), etc.

My business layer is very entity centric, really it's just the glue between the entities and the repository, with validation in between. I've seen many designs where the Service Layer is what holds a reference to the repositories (in essence skipping the "business layer"). In essence it serves the same purpose as my Business layer, it does the validation, however its' responsibility (and naming) is a higher level, more coarse grained business transaction. Using the example above the TradingService.submitTrade() will not delegate to any business manager classes, it would itself query the necessary repositories, perform all the validation etc.

I like my design in a sense that I can reuse a business layer method in multiple service calls, however I hate the fact that for every repository I have a matching business layer manager, creating tons of extra work. Maybe the solution is a different type of grouping at the Business Layer level? For example combine individual Manager classes like PhoneManager and EmailManager (note I have Phone entities and Email entities) into a logical Manager class such as ContactsManager (note I don't have a "Contact" entity type). With methods such as ContactManager.GetPhones() and ContactManager.GetEmail(), etc.

ADO.NET :: UpdateSong () In DAL - Create A Method Called Updatesong() In Data Access Layer?

Nov 16, 2010

I have a table with columns songID, Album, Artist and title. I have created a method called Updatesong() in data access layer. The SQL qerry in UpdateSong() method is

UPDATE Music
SET Title = @Title, Album = @Album, Artist = @Artist

int SongID = Convert.ToInt32(musicAdapter.UpdateSong(TextBox3.Text.ToString(), TextBox4.Text.ToString(),[code]...

Whatever I'm changing in the textbox are getting updated except title column. I dont no whats wrong in that. If I change the SQL querry in tableadapter as

UPDATE Music
SET Title = @Title, Album = @Album, Artist = @Artist

WHERE (SongID = @Original_SongID)

I get an error saying "No overload for method 'UpdateSong' takes '10' arguments".

MVP - Presenter And The Service Layer - Where To Declare Service Layer

Mar 27, 2011

I'm reading through Architecting Microsoft .Net Solutions for the Enterprise and I try to figure a couple of things out concerning the Presenter and the Service Layer.

First off, my Presenter needs to call methods that reside in the Service Layer, like initialize(), save() etc. But where do I place a reference to the service layer? Should it be at class level in the Presenter, or should I define a new service in the presenter methods itself?

Second - this isn't really clear in the book either - is this how the processing from the Presenter to the Service Layer works?:

Architecture :: Should The Unit Of Work Point To The Service Layer Or The Repository And Then The Repository Point To The Service Layer

Jan 26, 2011

Just wondering, in an ASP.NET MVC3 environnement with entity framework. Should the Unit of Work point to the service layer or the repository (and then the repository point to the service layer) ?

Ive saw two example:

* One where the unit of work and repository both have an instance to the service layer..

Link: Entity Framework 4 CTP 4 / CTP 5 Generic Repository Pattern and Unit Testable

Doesn't use a service layer but its obvious that one could be use in that case.

* Second where the unit of work have an instance to the repository which have an instance to the service layer..

What would be better ?
