Best Practice For Authorization In The Business Layer?

Sep 9, 2010

What is the best way (for a .Net 4 project) to implement authorization in the business layer. Simply I want to check whether a certain identity can access a certain action/resource.

I've tried to look this up in Patterns & Practices, but haven't found anything useful yet.

And what about PrincipalPermission of ASP.Net 2.0? Is this still relevant? What about maintenance?

I want to use an elegant solution, preferably (re)using role management.

Architecture :: Data Access Layer And Business Logic Layer?

Jun 24, 2010

I am building a web site following the tutorials on 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);

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.

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.


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 :: Getting Error When Connecting To Business Layer

I have a application with a 3-tier architecture. Onclick event of a button, I am calling a method in my code behind file. This method is defined in the Interface( Interface resides in my Business layer) and the implemtation of this method is given in the Data access layer.

The business layer and DAL are on different projects. I have compiled the entire solution and it complies OK. Now when I try to click the button I get the error:

"The method 'doInsertCust' was not found on the interface/type 'My.Type, MyTypeLibrary, Version=1.0.2371.15203, Culture=neutral, PublicKeyToken=null'.".

Note that I have already build the Business layer and DAL and the respective DLL gets automatically refreshed.

Architecture :: Set Images In Business Layer?

Dec 17, 2010

I am creating an ASP.NET MVC application and want to display an icon in the view based on a value of a property in the model. I guess I want to have the logic deciding which image to show in the business layer (which is in a separate class library project) but the actual images files in the web application's "Content" folder. Should I set the url of the image in the business layer? I don't want the business layer to know that is serves a web application, it can be a Windows Form or WPF application as well. If I set the url with System.Web.HttpContext.Current.Server.MapPath it feels like I am getting an unwanted dependency on System.Web, right? What are the options here?

Business Layer And Datasets / TableAdapter

I have a website and it was running great but wanted to move my business logic/datasets over to its own project.

That seems to be working well, I can access my functions etc from my bl dll. But I cant access my tableadapters like i used to be able to directly.

Do I have to make classes that access all those tableadapters or am I missing some reference I need to add?

I seem to be able to get the dataset for example mydataset But the intellisense doesnt pull up mydatasettableadapter

Architecture :: Passing Entities To Business Layer?

Mar 30, 2011

I am working on implementing a web application in ASP.Net by following the MVC design pattern (Not ASP.Net MVC). As part of the design, we have entity objects that has only properties as per the corresponding table structure and the idea is using these entity objects in the view layer and the same entity objects are passed to Persistence Layer for saving the data to the database. Business Objects in the business layer are responsible for interacting with the database.

As view creates the entity objects and passes to next layer, what would be the best practice to pass the entity objects to the business layer? Should the business objects accept data objects as parameters and interact with the persistence layer? Is there any other best practice to pass the required objects from the view layer to the next layer? As business objects also need to access the properties of the entity objects passed from the view layer, do we need any "translation" from entity objects to business objects?

the best practices to pass entity objects from view layer to the next layer and also how the entity objects created by the persistence layer can be used by business objects?

VS 2010 - Business Layer Constraint Error

Feb 22, 2012

I'm working on an application using a 3 tier architecture and I'm having issues with a business layer select method. Basically, I have a gridview control that is populated by an objectDataSource. The ObjectDataSource calls a select method in the my business logic layer to retrieve data. When the business logic layer calls a table adapter method, I receive the following error message:

Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints

This is my first attempt at a 3 tier design and I'm not sure where to start with the debugging process.

Also, the stored procedure that is used by the table adapter select method, creates a new column inside of the query. This column is not included in the datasets datatable. I manually inserted a new column into the datatable from the dataset designer. The new column was created to store the values that are being returned from the new column in the stored procedure. I'm not sure if this is the correct way to do this or not but it allowed me to access the column in the business logic layer methods.

Attaching Linq To Sql Datacontext To Httpcontext In Business Layer

Mar 20, 2010

I need my linq to sql datacontext to be available across my business/data layer for all my repository objects to access. However since this is a web app, I want to create and destroy it per request. I'm wondering if having a singleton class that can lazily create and attach the datacontext to current HttpContext would work. My question is: would the datacontext get disposed automatically when the request ends? Below is the code for what I'm thinking. Would this accomplish my purpose: have a thread-safe datacontext instance that is lazily available and is automatically disposed when the request ends?

public class SingletonDC
public static NorthwindDataContext Default
NorthwindDataContext defaultInstance = (NorthwindDataContext)System.Web.HttpContext.Current.Items["datacontext"];
if (defaultInstance == null)
defaultInstance = new NorthwindDataContext();
System.Web.HttpContext.Current.Items.Add("datacontext", defaultInstance);
return defaultInstance;

A majority of these functions only do parameter validation and actually calls the SQL server. Is this something that should be replace with an ORM? (Linq, nHibernate, Entity Framework)... or should there be more to this picture?

C# - Can Improve Business Layer Objects Mapping Into A Database

Sep 2, 2010

As I began writing web applications with I started with small projects that used a Linq-To-SQL mapper for database access to a MSSQL Server. After gaining some expierence I switched into a classic 3 tier with Graphic Layer, Business Layer, Data Layer. The only function of the Data Layer was to provide methods insert/update/delete without any logic and logic the form of selection methods.

Over the time I realized that it would be better not to provide the database classes up to the GUI (took some time unfortunately). I switched into using Business classes in the BL that are used for all operations performed by the BL and display by the GUI in the form of getting List from the BL. A great advantage is that I can provide additional properties that are not represented by the database itself. However, I did that mapping inside the BL myself with methods that mapped the corresponding BL class to the database class.

I guess thats where O/R mapper come in handy? Until now I haven't realized their purpose, but I think I just found it. I've recently tried out using the new Entity Framework with .net framework 4, but I'm only using it like the Linq-To-SQL DataContext.

Is there a way to achieve the mapping automatically? If yes, is that something the new Entity Framework provides or do I need to look for a O/R Mapper like NHibernate?

C# - Using Entity Framework With Existing Business Layer And Database?

I have an ASP.NET application with existing business classes and a database schema. (which I would like to keep) Currently I am using ADO.NET for the DAL, but I would like to switch to some advanced technology there for easier data retrieval.

Is EF applicable to my situation? Can I use it without splitting up my business classes and auto code generation? Can LINQ to SQL solve my problem better?

All I want to do is map my existing classes to the existing tables and dont have to handle details of the data retrieval myself.

ObjectDataSource And FormView: Add UI Edition Behaviour From Business Layer?

Nov 3, 2010

using an ObjectDataSource and a FormView.In the FormView I have a set of controls. When the FormView is in edition, I have in particular a ComboBox and a TextBox which are related as follows: when the ComboBox takes some special values, the TextBox must be read only or not. or the moment I get that behaviour as follows: the ComboBox triggers a postback when its selected item is changed and in the 'OnPreRender' of my page I get the value of the ComboBox and update the Readonly property of the TextBox accordingly.What I don't like with this method is that I don't use my object model which is consumed by the ObjectDataSource. The problem is simply that when the FormView is in edition there does not seem to be a way to get the instance of the object which is being edited. The 'DataItem' is null and I haven't found any way to automatically build a new object from the values in the controls to pass it to my business layer. Of course I could do the whole job myself by getting explicitly all the values in the controls, but that's not nice.
