Feb 12, 2010I 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.

Architecture :: Use STATIC Methods In Data Access Layer?
Feb 4, 2011I am developing a web application, which has Data Access Layer and this layer has only one class, in which all methods are static methods like static Insert, static Update, static Search. It has no properties. I am using these methods in my Bussiness Logic class for my users who are visiting my website.Now my question is : 1. Is it right to use static methods in this scenario ?2. What will happen if 10 users call Insert method at the same time ?

View 3 RepliesArchitecture :: Should Let External Classes Access Webform Controls
Sep 24, 2010I was wondering if you should write code so that external classes and functions of that external class can access the webform controls in the main class???
Or should you only use the external class to process some data, return that data back to the main class (that instantiated that external class object) and then have an internal function in the main class to deliver the data to the control? (back to the screen)

View 4 RepliesArchitecture :: Allowing Access To Multiple Customers For One User With Url Rewriting
Jan 27, 2010I am currently developing a solution in which the user logs in once and can work on multiple customers at the same time on my site.I've looked at all possible solutions involving sessionid having stored the customerid, to launching a new browser session so i could have multiple sessions for one users etc. I also looked at using cookieless sessions.But the all fail because it's not a simple solution and in my opinion a simple solution is most of the time a good and predictable solution.
Therefore i came up with the idea to use url rewriting(i've seen this used in other applications). When the user opens a customer, i would like to start his url as follows "~/Customers/xxxxxxx/*.aspx" where xxxxxx represents the customerid. and *.aspx represents a complete subset of pages of my site. This would allow me to use a simple technique to use multiple user sessions within a single asp.net session.
Now coming to my problem, I have never done some url rewriting, therefore my questions:
- Is this possible.
- Can i protect all the pages that need a customerid as input(come to think of it, if no customerid in the querystring, redirect to a selection screen would be sufficient).
- How do i adopt all urls used in a sitemap etc in a structured way.

Architecture :: Keeping Information In Memory That Any User Can Access Easily?
Mar 20, 2010I want to read some information from an xml file and store it ready in memory so that it can go out with every page response without being reloaded from the xml on every request.
What is the best way of doing this?
It looks to me like there are 2 options. Either create a class with static fields that the information is stored in. Or create a class with public fields that the info is stored in and create an instance of that class at application level.
Is that correct, are both of those options viable? or will I not be able to access the fields in the second method without creating an instance of the class in the code that responds to the page request(basically if you create an instance of a class at application level can you use that instance from within code anywhere in your website as long as it is public)?

View 5 RepliesPhp - MVC Architecture Decision - Refactor Existing Approach Into Controllers / Views And Database Access
Feb 12, 2011Consider 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 :: Using Data Sources Vs. Using Data Access Layer To Populate Presentation Controls?
Mar 17, 2010We are using a tierd design with a Data Access Layer and classes for everything we need. This serves as an advantage because we do not have to write querys over and we can separate the Presentation layer from the Data Access Layer and Business Rules.I have always in the past populated GridViews, DataLists, repeaters,etc with SqlDataSources. This is what I have become accustomed to and I feel like it is simple. For querys such as Select * from Members, I feel like using a DataSource is simpler than having to go in the code and calling methods to populate and DataBind these presentation controls.
I am working with a gentleman who has introduced me to the world of Data Access Layers and we are breaking everything down into simeple, but effective queries to populate controls and do what we need to accomplish with this application. He is not very approving of using any type of DataSource. We are disagreeing on the time and place to use these class methods to call the database.So my question is, which is more widely used in the programming world? Do most people use DataSources to populate presentation controls regardless of the Data Access Layer they are working with? Which type of queries are best suited for a DAL - simple, populating queries or complicated joins and upserts?
Architecture :: Data Access Layer And Business Logic Layer?
Jun 24, 2010I am building a web site following the tutorials on asp.net. I am using dataset as data access lay, and writing classes to access the dataset. But the example is just basic ideas, how do I retrieve individual table column value in the business layer?For example, if I have a table called Product, I only want to find out what is the product name by product id. I did this in my ProductBLL:
public ProductBLL
{
public int GetProductName(string productId)
{
ProductDataSet.ProductDataTable prodData = Adapter.GetProductById(productId);
[code]...
Is there a better way, or am I doing this correctly? Can anybody give me a reference to a more complicated business logic model?
Architecture :: Access SessionState - Via App1 To SessionState From App2?
Aug 21, 2010i'm interested to do the following - i geuss, i have no option to do that:
we have our "mainapplication" on a DB; we are tracking user-login status by switching a bit in the DB in the users data row.
we hvae a second application, the backend, which is the administration tool.
(the applications are put in seperate diretories on HD)
sometimes, we need to block/ban users. in some cases the users are logged in, when we "see them in action".
i'd like to build a button in the backend-application, which logss-out the user from the mainapplication.
for sure: i can access the same DB and switch the bit to "know" he's offline, but this will not kill the session on the mainapplication.
because: if a user is on/offline is also indicated by the session in the IIS. and as the IIS-session is active, the user may be already banned - but he will not be logged out automatically (and showing something like "you have been logged out because of a ban) one option would be to call the DB by each page-load to find out, if the user is logged on.
