Re: Web service as Datasource in the DAL

jclark434175 — Thu, 05 Nov 2009 05:00:00 GMT

Yes. We have a similar setup on a on project I am currently working on. For starters the best way to break down a n-tier application is to explain the layers and what they need to perform/process.

Presentation Layer - In terms of ASP.NET, code-behind, aspx markup pages

Business Logic Layer - Contains business logic in terms of classes that have functions that perform operations/business logic

Data Layer - Contains your data access code; whether it be exposed as web services, database, xml, in-memory, whichever

(Optional) Service Layer - Service layer contains service agents that can be used to communicate with web services

Now that we understand all the layers, let's talk about your scenario. I think what you are in the need of is the Repository Pattern. Here is an article that is good at explaining its uses - http://www.codeproject.com/KB/architecture/linqrepository.aspx . The repository pattern will help you decouple your types of back-end data sources from your domain model or business entities. Either way if you don't end up using a repository pattern you can also look using a mapping layer instead. A mapping layer will allow you to build DTO (Data Transfer Objects) objects which will allow you to expose objects to your front-end that are not tied to your back end data model.

Hope this helps

basic doubt regarding design patterns

anilkumar.ms — Tue, 27 Oct 2009 04:00:00 GMT

Hi,

i know that design patterns are of three types and they are creational, structural and behavioral. May i know how they'll be used in a project.

Thanks & Regards,

Anil.

Hi,

I am looking for some advice and comments on the proposed architecture for a new web application that I am about to start.

Basically, the application will consist of a static content and then multiple non-static parts. The static content would more than likely be some sort of CMS and the multiple non-static parts would be a series of web forms.

We will be using ASP.NET (possibly MVC) and version 3.5 of the framework with SQL Server 2005 as the database.

I was thinking about having a seperate websites within IIS for the static content and then a seperate website for each of the non-static sections of the site. The main reason being that we could then seperate everything out and development teams could work on each section independently. This would allow us to add more and more of the non-static sections as/when required and it would also allow us to perform maintenance on each section without effecting any other section.

I am sorry for being a bit vague but the concept is still a company secret so I cannot divuldge what each of the "non static" sections are but if we say for example that they are pages for capturing information about different animals then that may help to make a bit of sense.

I was thinking about a virtual folder for the static content (CMS) and then a seperate virtual folder for say Dogs, another for Cats, another for Horses etc. etc. with each "animal" running in it's own application pool.

One area of concern is how do I manage security, specifically the user's login. Ideally, we would force the user to login via the CMS and then pass the login details to each of the Animals as we wouldn't want the user to have to log back in during visits to each of the virtual folders etc. Would simply encrypting the login details and passing them as query strings be suitable?

The site(s) would also need to be load balanced, can you think of any issues with this design regarding load balancing?

All comments and suggestions would be welcomed.

Thanks.

Re: Rewriting an Access Project (ADP) - Web or WPF - Suggestions and Tips please

dministrator — Fri, 25 Sep 2009 04:00:00 GMT

Thank you for taking time for writing such an involved response. Very helpful. Thank you.

Some more points about this application:

Technical expertise is not an issue as we have people, myself included, working on everything from BizTalk, WCF, WWF and many other Microsoft technologies.

I do not know the full history behind this Access application which I inherited, but one of the clincher in favor of using Access + Citrix seems to be that, Access had everything they needed within one platform: Reporting, UI forms, interface to SQL Server Database etc.

The terminals are all windows dumb-terminals, or as we like to call them - 'unwise terminals'. The application is represented by a short cut on the desktop; when dbl-clicked will launch the Access ADP project via Citrix. I don't think any of the terminals have IE installed right now.

If you have more to add on this topic, please do so. Thanks again for your response.

web application architecture

swapnil.naik — Wed, 23 Sep 2009 04:00:00 GMT

Hello,

We're in the search of an ideal web application architecture (ASP.NET) (like CSLA.NET)

We want to meet following criteria,

it should be..

web service based (so that SOA implementation would be easier in future) (CSLA.NET is based on remoting techniques)
ASP.NET server controls support (since, ASP.NET MVC doesn't support)
N-tier architecture (easily extensible)

if such architecture already exists, please let us know.. else, guide us how to achieve this minimal criteria.

Thanks in adv.

problem with generics

        {
        }

gives me error

Maintaining and displaying historical data after modifications

bgray — Thu, 03 Sep 2009 04:00:00 GMT

Haven't seen a post similar to my problem so posting. How can you model your database to handle data entry wherein you must keep and show correctly the entered data historically. As an example:

You have a teacher evaluation page that has a bunch of dropdowns(selects) where you rate a teacher for the year. Say there are 10 dropdowns representing evalution areas and each dropdown has unique items(option) text and values. One dropdown could have 5 items, another 6. The dropdowns and select items are all stored in the database. So a teacher gets rated for 5 years on these 10 areas by lots of students. You got lots of data about the teacher now. Say you have some pages that shows details about the teacher's evaluation over the past 5 years....some graphs or average score per year, or better yet, the actual values an individual student submitted for any year (anonymous of course). OK, now the number of dropdowns change or the items in the dropdowns change via perhaps some admin page for configuring teacher evalutions. Say 1 dropdown gets removed, another added with new items, and another has the text and values of its dropdown items changed. And so a few more years go by and the teacher is rated on these newer updated criteria. So...now how would I keep the data accurate when a teacher wants to see an evaluation from the very first year. For that first year, 1 dropdown no longer exists, another dropdown has it's orignal values and text all changed. If I use the current values of that dropdown, then it won't be an accurate depiction of what the student filled out at that time.

Any design help on this sort of general scenario would be greatly appreciated. In one project every item that could be changed had a 'DateEffectiveStart' and 'DateEffecetiveEnd' columns in the database so when I brought up historical info for that day, i had to get everything where the day we between those two columns. Seems like there has got to be a better way.

If you are thinking about SXSW interactive this year, check out the panel picker. Panels are chosen largely on the community interest.

Here are a couple that have been submitted that are of interest to me.
