What would be the best way to structure orders for a restaurant (available languages are php and javascript)? Since there are multiple tables (the ones you keep things on...), I thought of using objects in javascript. But I am quite new to javascript and absolutely new to OOP, so I'm not sure whether this is the best solution, and whethe...
Hi, I'm weighing up building a light-weight email marketing system into our existing platform I've developed. The other solution is to use an already existing tool (e.g campaign monitor / mailchip) and connect it into my platform as much as the api allows. The connection will be a little more cumbersome for the user, there will be diff...

But there is such scenario where if a particular condition hit in object of class B, it has to create another object of class B.

When the user selects the particular control in the UI, all the editable properties should be visible in the property window. The user control should have control on what properties it want to expose for property window. The user c...
I find myself breaking this pattern all the time. YAGNI - You Ain't Gonna Need It I am only a Junior Developer, but I find even Senior level developers doing the same thing. "Well, this system might use it, and this one, so let's design for it." Sometimes, I catch myself, but most times I run wild. Does anyone have any t...

The user creates the following Categories: C1, C2, C3. The user creates the following Projects, Category associations: [P1, C1], [P2, C2]...
I am working on a piece of C# web application that has a page (MainPage) with a small area to display a gadget. There are several kinds of gadgets implementing a main interface (IMainInterface) and an optional interface (IOptionalInterface). In MainPage, when interacting with the gadget class, it uses following syntax: MyAPI api = new ...
We are designing a large system and are using PLINQO for our data access. The problem doesn't lay in PLINQO but rather LINQ, I think. We want to make a modular design, ie possibly having multiple and different datacontexts. LINQ doesn't like this. Has anyone thought of a solution, issues or alternatives? Most things I see out there ...
If I need two modes in my application what design pattern would I use so I can prevent ugly conditional code? App is currently MVC, but I don't want conditional code in my controllers and don't want two controllers for each view unless I have to. Any suggestions? ...
I am writing a fairly complex Java server application which has a significant background processing portion in addition to the usual request-response processing. Some of the background processing is done in a cron-like fashion using Quartz framework. Other tasks are more of on demand - if a new client connects it creates additional job f...
I need to store long strings in a database. the string may be 5 or 6 sentences long. do you think this is a good design strategy. or should I store an id for that string and then create a relationship with another table that contains the location of the file storing the string. could you please give advantages and disadvantages of both. ...
Hi, I am wondering whether there is any methodology to design the program logic which is agile-proof. Currently for example I am developing an application for video recording and uploading. At the beginning it was planned just to enable the user to select the stored recordings from the library and edit title or upload the selected vide...
my app asks the user yes-no questions, user replies using a uiswitch on screen. i've been thinking about creating a custom version of the switch that would display yes/no instead of on/off and would use a green/red background as an indicator of the value. after creating a mock up i'm not so sure this is the way to go. using the default s...
I'm writing a program to do a search and export the output. I have three primary objects: Request SearchResults ExportOutput Each of these objects links to its precursor.

Does anyone know of a good article about how to represent a JSF application in JSF? I found the article on JSF central about the storyboard approach. However, this is incomplete. This is the only resource I can find on this subject. Any recommendations? Thanks in advance, Zack ...

This is pretty basic, but sort of a generic issue so I want to hear what people's thoughts are. I have a situation where I need to take an existing MSI file and update it with a few standard modifications and spit out a new MSI file (duplication of old file with changes). I started writing this with a few public methods and a basic inpu...
With reference to an earlier question of mine on parsing fixed length field files, I have come up with another question at issue. I will probably be using a customised version of the FileHelpers library, with field start and length attributes that dynamically read the values for their target properties from a config file. The text data...
It's a pretty basic design question, but still: I have a header in one file and a few pages which load in succession in other files. I want to add a progress indicator (just an image of a 1/3, 2/3 and 3/3 filled bar) to each of these pages, but I want the bar appear on header, which is in different file and higher in flow, so negative m...
