How to track changes to business objects?
I get the concept of creating a business object or entity to represent something like a Person. I can then serialize the Person using a DTO and send it down to the client. If the client changes the object, it can have an IsDirty flag on there so when it gets sent back to the server I know to update it. But what if I have an Order object...
Business Objects, Validation And Exceptions
I’ve been reading a few questions and answers regarding exceptions and their use. Seems to be a strong opinion that exceptions should be raised only for exception, unhandled cases. So that lead me to wondering how validation works with business objects. Lets say I have a business object with getters/setters for the properties on the obj...

Architecture for a business objects / database access layer
For various reasons, we are writing a new business objects/data storage library. One of the requirements of this layer is to separate the logic of the business rules, and the actual data storage layer. It is possible to have multiple data storage layers that implement access to the same object - for example, a main "database" data stor...
Business Object DAL design
When designing business objects I have tried several different methods of writing the data access layer. Some have worked out better than others but I have always felt there must be a "better" way. I would really just like to see the different ways people have handled the DAL in different situations and their opinon of how the techniq...

System.Drawing.Image for Images in Business Objects?
Hi Folks I'd like to store an image in a business object. In MSDN I saw that the System.Drawing-namespace provides lots of GDI+-features, etc. Is it okay to store an Image in an System.Drawing.Image class in business layer (which is a class library "only"), and thus including a reference to System.Drawing too? I slightly feel just kind...
How To Publish Business Objects Query Service
We are trying to copy a BO Query Service from one Universe to another. If you use the BO Query As A Service(QAAS) tool you can do this, but end up basically recreating the query service. It seems like the BusinessObjects.DSWS.* libraries allow you to read and write query services, but those don't appear in the QAAS tool. I think that ...
Need advice on combining ORM and SQL with legacy system
We are in the process of porting a legacy system to .NET, both to clean up architecture but also to take advantage of lots of new possibilities that just aren't easily done in the legacy system. Note: When reading my post before submitting it I notice that I may have described things a bit too fast in places, ie. glossed over details. I...
Automate download of BusinessObjecs Web Intelligence reports
I'm tasked with automating the retrieval of a couple of BusinessObjects Web Intelligence reports and further processing thereof. I have no other means of access to this data (this was the first avenue I followed), so I will have to do some screen scraping. Alas, the interface seems user-only. Grr! Has anyone done this before? Like to s...

Should I have one class for every database I use?
First, let me explain what I am doing. I need to take an order, which is split up into different databases, and print out this very large order. What I need from the orders is about 100 or so columns from different databases. The way I was doing in was querying with a join and assigning all of the column values to a variable in my one la...
Abstracted References Between Entities
An upcoming project of mine is considering a design that involves (what I'm calling) "abstract entity references". It's quite a departure from a more common data model design, but it may be necessary to achieve the flexibility we want. I'm wondering if other architects have experience with systems like this and where the caveats are. Th...
Loading Business Object Hierarchy with One Database Call
Hi, I would like to know what the best practice for populating a business object hierarchy (parent/child/grandchild) structure is from a single database call. I can think of a couple ways to accomplish it off the top of my head such as: left-joining all the relations in my sql statement then use looping and logic to fill the business ...
Force validation on bound controls in WPF
Hello. I have a WPF dialog with a couple of textboxes on it. Textboxes are bound to my business object and have WPF validation rules attached. The problem is that user can perfectly click 'OK' button and close the dialog, without actually entering the data into textboxes. Validation rules never fire, since user didn't even attempt ente...
Best Practice for Subset of Business Object Fields Structure ?
If I have a business object with 50 fields, and I need to populate something like a drop down list or gridview with only 3 fields from the business object to allow quick browsing. Is it best practice to load the fully populated BO then just grab the few required fields in your presentation layer ? It seems inefficient to populate a c...
