    • Is it possible to use two different data sources with two different concrete DALs

      Hi, What would be the proper way to code if you have two different data sources? For instance, in my project I have a SQL2008R2 Data Source with the main data, and a XML file which defines the filter conditions of what to retrieve from the main database. I.e. the XML file have the criterias defined which...

    • How To: DALs for both SQL and SQLite in same project

      I'm trying to build a connected WinRT app, and have realized I really need to provide offline storage capabilities. So I'm going down the road of using SQLite on the client and SQL Server in the cloud. What I think I need to do is to use two different DAL implementations: one for SQL Server,...

    • Silverlight CSLA - BO invokes DAL

      Hi All, I've just completed watching the CSLA Core and MvvM video series. We currently are utilizing the standard DataPortal_XYZ methods into an Silverlight application to retrieve our data but we want to move to utilize a separate DAL (BO invokes DAL) to have both DataAccess.MsSQL and DataAccess...

    • ObjectFactory with different types of BOs

      Hi everyone, Is it possible to use a single ObjectFactory class that determines the type of BO to operate on at run-time? There is a custom base class (e.g subclass of ReadOnlyBase<T>) that has the ObjectFactoryAttribute applied on it and all its subclasses should use the same ObjectFactory, unless...

    • To use or not to use DTOs

      Hi Rocky, On Using CSLA4 - 3 Data Access ebook you show two implementations of Encapsulated Invoke model: - DataReadder DAL interface - DTO based DAL interface As far as I can see, the former uses a data reader but just for the fetching part and uses parameter passing otherwise. The later uses DTOs for...

    • Invoking an Abstract DAL from within the Business Object

      Hello, To paraphrase Rocky from the 3rd Csla 3.8 video, while discussing a demo project which invokes an abstracted DAL from within the BO (starting at about 1:10:48) In a 3 tier model you don't even deploy your concrete data access components to the client. You simply deploy an abstract DAL router...

    • Re: Unit Testing with the Repository Pattern

      Hi Justin, We do have one Repository and one Context object per business object. Yes this leads to a lot of objects but overall, if you think about it all basic CRUD operations are almost identical, all that differs are the column names and the table name. While building the Contexts and Repositories...

    • Re: Unit Testing with the Repository Pattern

      Hi! I agree with Scott about the learning curve and the overall benefits of using EF over L2S. Regarding the Repository pattern implementation, my team implemented it very successfully and we are particularly happy of this decision. The repository to instantiate for each BO is configured in a unity config...
