I'm learning GRASP pattern at school and I have a question about the Creator pattern. Let's say you have three class, Computer, UserRespository and User. One of the rules of the GRASP Creator pattern tells you to assign the responsibility of creating an object to the class containing those object. By following this guideline, UserRepos...
I'm working on my first DDD project, and I think I understand the basic roles of entities, data access objects, and their relationship. I have a basic validation implementation that stores each validation rule with it's associated entity. This works fine for rules that apply to only the current entity, but falls apart when other data i...
I'm using Archiva as my repository manager. It is setup so the users hit the archiva repo and if it doesn't hvae it, the archiva repo will then check the maven central repo (the internal repo proxies the maven central). Now if I want to add a new dependency to the archiva repository, is there a command I can run to tell it to go fetch it...
I have an SVN repository that has multiple projects inside of it, each one of those with a tags/branches/trunk structure under them like this: Project 1 - trunk - tags - branches Project 2 - trunk - tags - branches This goes on for ~40 projects. What I would like to do is clean up any abandoned branches that may exist, however I do...
I have a repository (CustomerRepository) that retrieves data from the data layer. Most of the business logic is in the entity class (Customer) that the repository either accepts or returns. However, where do you put the global entity business logic (that applies to all customers). For instance, I may not want to return all customers to c...
Can anyone recommend a good hosting provider where we can host our Maven 2 repository and continuous integration process? We're very open minded about the implementation and are willing to use any OS, CI software and repository software so long as it gets the job done well. Thanks in advance ...
Hello Quick Q for you pattern experts out there. I want a Repository pattern that is de-coupled from the actual data access tech, as I've not decided on that yet and I want it to be flexible. So, this could be L2S, L2E, NHibernate, Lightspeed or anything. But I'm getting confused about this UnitOfWork thing. In the L2S world, this...
I've created a ubuntu/debian package that installs an application that depends on R. When installing I want the package to install R from the repository at: deb http://cran.uk.r-project.org/bin/linux/ubuntu jaunty/ because this repository contains the up to date version of R. I've tried adding the package to the sources.list file from ...
So, I've read all the Q&A's here on SO regarding the subject of whether or not to expose IQueryable to the rest of your project or not (see here, and here), and I've ultimately decided that I don't want to expose IQueryable to anything but my Model. Because IQueryable is tied to certain persistence implementations I don't like the idea ...
I have two classes, for this example, that are partial classes against LINQ-to-SQL model classes. public partial class Foo { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public IEnumerable<RuleViolation> GetRuleViolations() { yield break; } partial void OnVal...

Hi there, i am trying to tidy up my code, i have a number of projects that have References to my Service Layer i.e the DLL. What this means is that when i distribute a new service layer i have to upload a number of service layers which are generally the same.. Of course using the ADD Reference is very fast as its one assembly talking t...
I've just graduated from school with a CS degree, and before getting a job, I'm trying to teach myself as much as possible. A large problem I'm having is that I have few people to talk to about my code, and really improving the way I write programs. I figure the best way to do this is to see other people's code, and to see different wa...

I'm getting into using the Repository Pattern for data access with the Entity Framework and LINQ as the underpinning of implementation of the non-Test Repository. Most samples I see return AsQueryable() when the call returns N records instead of List. Could someone tell me the advantage of doing this? Regards ...
