Hi Folks, I´ve some trouble with implementing Core Data to my existing iPhone-Project.

I have a conceptual model in EDM where one of the entities has a property which is essentially a big value object whose properties aren't really useful as columns in the datamodel. I'd like to apply the Serialized LOB pattern to it so that I can fit it into a 192 byte binary column. How do I map this in the EDM v4? Is it even possible a...

Hey all, Simple question. Is it possible to add a block of HTML in a SimpleXMLElement (or as a matter of fact, DOMDocument) node without auto-converting the HTML data into entity format? For example, take this snippet (with DOMDocument here, but SimpleXMLElement behaves exactly the same): <?php $dom = new DOMDocument( '1.0', 'utf-...
Hello. I've been evaluating MindScape Lightspeed for the purpose of Model creation. So far I am satisfied. I was further looking for OOTB (actually some professional quality code) providers for MySQL for ASP.Net. I've come across 'dotconnect for MySQL' from Devart. This looks like fitting the bill for the latter requirement. It also has ...

Good day, I currently have an Entity that has a where clause set on it. I want to put that where clause on a filter and have that turned-on by default (so that I won't break any existing functionalities). I want to turn it into a filter so that I can disable it because I have a use case wherein I need it disabled. How can I do that in...
I have some data bound controls which are bound to a bindingSource which is bound to a entity model. The problem I've run into is I need to be able to allow the user to filter to a specific record to update information and when a bindingSource is tied to an entity model filtering is disabled. What would be the best way around this? Sh...

I have been trying to reason about the best way to handle whether it is generally good practice to implement hashcode and equals on entities (I mean entity in the general sense but in most cases it will be a JPA entity). In Chapter 24 of the Hibernate manual http://docs.jboss.org/hibernate/core/3.3/reference/en/html/best-practices.html ...

Example: I have two tables in my database called classA and classB, and one table called classA_classB. The last one just defined two int fields with foreign keys to link between classA and classB. So one classA can have many classB, and many classA can link with the same classB. Simple stuff, so far. The problem is, in my special case,...

I'm fairly new to Core Data, have looked through many tutorials and forums and haven't found the elegant solution to my problem: I've got three entities in my model: Worker, Task, and SubTask.
