Hi guys, I have several tables in my ERD which which I would like to combine in a relational manner. I have several use cases, but I completely lost track of what kind of relations to use between the tables. Every user can work on multiple projects. Every user has one specific role per project (Manager, Contributor, User) Every proje...

Hey I have the following situation: a WinService which is processing some stuff from a queue, writing to other tables (during processing) and after it finishes it deletes the entry and moves to the next one. I would need a mechanism to determine if the instance is alive and going and if not to start or wake up a second instance. What I...
We're in the analysis/early design phase of a future Swing application where persistance is provided by a database (probably an alternative between Oracle and mySql depending on the customer's money). Basically, the application will feature two kinds of modules : One "admin" subsystem to feed and maintain a set of referential data ; X...

..where do you begin? As a basis for any design - for instance a package - where do you as a developer start. I start by mapping out the requirements and breaking them down into sub categories and from this objects and methods. Usually takes a while before I start drawing it out by hand - then that goes through a few versions. But I a...
Not sure if the title captures what I'm trying to say here. When designing in OO should I be splitting my objects up into their most specific areas - so if I have a factory object that deals with creating objects but later on i come across a way of creating objects for another purpose even though they may be the same objects is it worth...

I find one of my weaknesses to be applying the theory I know in actual projects. One such theory is application design. I have never formally designed an application before beggining to code. I am developing a simple microfinance loan application for a client and I for once want to do things properly. Hence I am trying to design the syst...

Sorry for another non programming question, but I'm using Quartz.NET, a scheduler for .NET applications, for a Windows Service which allows users to schedule transferrig of files that match a regular expression from various sources - for example the user may schedule a job to occur every day at 6pm that transfers the files from a networ...

Hi, I'm soon to kick off a web app using ASP.NET that allows for the manual entry of new data and update of existing data. The company has an existing template that uses a 3 tier structure with standard user interface, business layer and data layer.

I have an Employee object which aggregates a few other objects, such as HRData and AssignmentHistory. In the past all of this logic was contained directly in the Employee object, but for testability and manageability I've split it to use aggregation. However, instead of exposing the aggregate objects directly, I've used delegation so tha...
I was taught about formal systems at university, but I was disappointed how they didn't seem to be used in the real word. I like the idea of being able to know that some code (object, function, whatever) works, not by testing, but by proof. I'm sure we're all familiar with the parallels that don't exist between physical engineering and...
