Master Data Deletion in Large Database Applications

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :ASP.Net

I am working on School MIS application and apparently, it has many Master profiles, like School, Student, Class, Division, Employee etc. In order to keep my database integrated and to maintain the consistency of data whenever someone deletes a master data then everything related to that data also gets deleted.

However, as the application is progressing I am wondering if it is a right way to do it because when someone deletes a master data then there is hell lot of data which would also get deleted. And the related data which would get deleted would in turn have other related data.

So if in my application if someone would delete a school then all the information related with a school like Students, Classes, Sections, Division, Employees should also get deleted and Students in turn would be associated with other data which should also get deleted.

I was wondering what would be the best approach? What if someone deletes a master record it by mistake, though we would take the confirmation before deleting but if by any chance someone does it by mistake then it would cost the organizationa lot:)

1) Should we really provide a feature to delete a data or when user tried to delete a data then maybe we can deactivate it and all other related data by setting some flag in the table.

2) If we have to delete the data then, should we just take confirmat

Routing in dynamic data applications


Im using ASP.Net 4. I tried to modified the code according to following video tutorial. http://www.asp.net/aspnet-in-net-35-sp1/videos/how-to-enable-table-specific-routing-in-dynamic-data-applications

But Product page directs only to ListDetails.aspx page.

This is my code :

<%@ Import Namespace="System.ComponentModel.DataAnnotations" %>
<%@ Import Namespace="System.Web.Routing" %>
<%@ Import Namespace="System.Web.DynamicData" %>

<script RunAt="server">

    public static MetaModel DefaultModel {
        get {
            return s_defaultModel;

    public static void RegisterRoutes(RouteCollection routes) {

Linq - add data to database then email user the details

I'm not sure how to structure the code for this but what I want to do is be able to add data to a database, and once this has completed successfully, then email the user to say the details have been added successfully to the database.

I need to:

1. Check that the relevant data has been added into the database then

2. Email the details of the relevant data when completed. 


Thanks in advance for your help,




Persist large dataset across ASP.NET pages. No database


Can anyone give me suggestions on how to implement the following requirement?

1. A online wizard (step-by step operation) processes user requests across several ASP.NET pages.  The session data is stored in memory until the user submits the request.  Once the request is submitted, a XML file is created and the data are passed to XML.

# Case Study: The parent page has a "select" button.  Click "select" will pop up a child page.  The users can select 1000+ items from a datagrid in the child page.  Once the user clicks "confirm", the selected items in the child page will be populated to the selected item gridveiw in the parent page.  The user can keep selecting more in the child page and the selected items will be appended to the gridview in the parent page.


- What's the best way to extract strings from a text file and convert to a dataset in memory and then present it in a datagrid in UI?

- What's the best way to persist and manipulate a large dataset across pages?  Session? or ViewState? Can it be accomplished by LINQ?

The app doesn't interact with a DB.  Once the request is submitted, it will convert the in memory data to a XML file.  What technology can be used to accomplished this?&nb

Metadata: Create a Database Schema Repository with Meta Data Services in SQL Server 2000


SQL Server 2000 Meta Data Services is a repository technology that stores and manages metadata for SQL Server. Instead of building database schemas over and over, Meta Data Services allows you to freeze an entire schema for use in other projects. You can also use these schemas for training, testing, or debugging. In this article, the authors will review the various components of Meta Data Services and show how it can be programmed using a Visual Basic client, XML, and XSLT. They will also show you how to manage and manipulate your metadata by generating a simple database schema using a SQL Server repository.
