Access :: Database Architecture - How to Design The Data Access?

Feb 12, 2010

I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

Php - MVC Architecture Decision - Refactor Existing Approach Into Controllers / Views And Database Access

Feb 12, 2011

Consider the following scenario: Page written in classic ASP or PHP, which is rendering a data report (series of HTML tables for simplicity). There is one main database query and then multiple sub queries as the page renders. The report is split into sub panels, which correlate to a sub query. Therefore:

Main database query. Loop over result. For each row, execute sub query and render report panel. How would you architect a similar report using the MVC pattern? This can be split into two parts: Efficiency at database level of multiple queries, which are dependent on values from an outer query. If all data was processed and prepared in the controller, would this also be deemed inefficient if looping within the controller and then again in a view to render. Could sub controllers be used or sub panels, which encapsulate smaller sections of logic i.e. loading data and rendering report panel.

Architecture :: Abstracting Web Services?

Jul 25, 2010

I have 2 web services. They are identical in every respect except that one points to a test schema and the other one to production. I'm in the middle of writing the class that will use these web services but I'm not sure how to do what i'm trying to do.What I need is a class that does the work of consuming the web serivce, and I want to pass to it either the test or prod serice and and it be transparent insde of the class.

So..testSerive and prodSerice are idential, how can i have them inherit from something so that i can pass that something to my consumer class?

Architecture :: Entities In Client Application Using WCF Web Services?

Jun 16, 2010

Can some one inform me whether I need to replicate the same set of entities in the client which are similar to that of the ones in the server? I have planned to start a proj with service functions as wcf services and in turn they are getting referred in silverlight client application.

Incase if i need to consider casting to or back from the return value lists of service methods in the server, should i be creating entity class in the client application as well? Or is there a work around? Something like exposing the entities from the server just as the services functions?

Architecture Switch From Page And JSON ASMX Web Services To MVC

Feb 6, 2010

there's an .aspx page that does absolutely nothing in the codebehind, but contains the markup for the page in the Design View. Then we have an .asmx web service that receives requests with JSON content-type. These are called by the JavaScript in the page. This web service returns .NET objects serialized to JSON in response to these JavaScript Ajax HTTP POSTs. I'd like to switch to MVC but am not sure to how switch this architecture. Basically what we're doing is two things:

1) Replying to GET /MyPage.aspx with HTML markup that represents the page
2) Replying to POST /MyPage.aspx/WebMethodName requests with .NET objects serialized to JSON.

It seems like MVC would be a good way to eliminate the need for a Page object (again, the codebehind isn't used--only the HTML markup in the .aspx file is) and an .asmx web service. No? What do I need to start changing to accomplish this switch? Is it straight-forward? Painful? Someone at work already has an MVC page running in the same directory as my Web Forms .aspx and .asmx web service, but I don't see anything in the directory about Routes, so I'm confused. He's got a Views, ViewModels, and Controllers subdirectories.

Architecture :: Webserver Splitting Up Services Or Making A Single Big One?

Apr 1, 2010

I'm planning to make an ASP.NET webserver that provides all kinds of functions, like an API. There will be quite alot functions that can easily be grouped (datasystem, userAccount, fileSystem, and so on). I can make multiple services (asmx files) into a single webserver, and let the clients connect to whatever service(s) they need. However, I'm not sure if it's a wise thing to do... Pack everything into 1 big service(1 asmx file), or split up into many smaller services? How about:

- performance/memory on the server (a client that connets with 1 or 6 services)

- Maximum connections (we will use a Windows XP Server edition computer)

There will be about ~30 computers using it. In a worst case scenario, they each computer could make use of 6 services at the same time, if I decide to split it up. A single client could make use of the fileSystem, account, dataSystem and several other things at the same time.

Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )

Unable To Access SQL Reporting Services On Shared Site With Themes Enabled

Jun 1, 2010

I am having some trouble with my IIS web server & SQL reporting services.

At the current time my site is playing host to both reporting services (/reports & /reportserver) as well as my personal website (domain.com)

Only just recently have I implemented a Theme on my site and as such I have placed a statement in my web.config file directing it to apply a certain theme in the following manner:

<pages styleSheetTheme="General">

Because of this when I try to access the report pages it fails, telling me it couldn't find the Theme. So, what I did was locate the source files for the /reports & /reportserver directories and placed the App_Theme folder in them hoping that would sort everything out.

What I am getting now is the following error:

*Using themed css files requires a header control on the page. e.g. head runat="server" *

Does anyone know how I can get around this? Do I have to hack the SQL reporting aspx pages? I do NOT want to remove the web.config declaration.

WCF / ASMX :: Access Denied And Null Returned While Accessing Web Services From Remote Server?

Sep 2, 2010

writing a web Service and one of its web method, I want it to download a png file in form

of buffer from remote server. And My consume application will write that buffer retured by Web service in to file on User's Computer.

However, I am able to do this using Local Web Service but when I published that service on my web server, I always get null retuned

And even in one of my test code while copying file from that server , I always get Access Denied.

Following things I have done for above issue.

1] I even tried making the Anonymous user for the web service the system administrator (with the correct password), to no avail.

2] I also tried sharing out the folder I'm pulling files from to allow access from Everyone.

[Previously same service was working fine on another remote server with IIS 7.0, we checked server IIS Settings but in vain.]

if you know where we are mistaken guide me to resolve this issue as its very urgent.

.net - Silverlight RIA Services With Different Database Providers?

Jan 31, 2011

I want to create a Rich Internet Application in Silverlight. One of the requirements is that the back-end of the application should work with different database providers (SQLServer, PostgreSQL, Oracle). I'm planning to use Entity Data Model to represent database objects and Domain Services to expose these objects to the client.The problem is that I don't have a clue if the same data model can be used with different database providers and how sophisticated that would be to change the provider without recreating all the model.I want the application to be reusable on different environments, so that i can import the same database schema to any existing database, change the provider in the ASP.NET web application and that's it.Is it doable? Or maybe there are other ways to achieve similar functionality?
