What is Data Mining - A Simple Introductory Note

Sun, 13 Sep 2009 15:30:00 GMT

According to MacLennan et al. (2009), data mining is defined as "the process of analyzing data to find hidden patterns using automatic methodologies." Consider the following simple example that explains this concept. By analyzing the data on the items purchased from a supermarket or a chain of such stores, information on the products that are sold most can be obtained and accordingly supply of that particular products are increased and vice versa. Data mining, in short, is an analytical activity that studies the hidden patterns in a huge pile of data after appropriately classifying and sorting it.

Mon, 16 Mar 2009 19:16:19 GMT

Very simple explanation of : Although the placement of such predicates does not make a difference for INNER joins, they might cause a different result when OUTER joins are involved. This is because the predicates in the ON clause are applied to the table before the join, whereas the WHERE clause is semantically applied to the result of the join.

Unit Testable HttpModule and HttpHandler - Kazi Manzur Rashid's Blog

Thu, 12 Mar 2009 21:31:11 GMT

With the new System.Web.Abstraction namespace we can now easily write unit testable HttpModule and HttpHandler. In this post, I will show you how to write unit testable HttpModule and HttpHandler. Prior the release of System.Web.Abstraction the problem with unit testing of these web infrastructural items is HttpContext, it is sealed, no way to mock it with Rhino or Moq. The only option is to create the wrapper objects of these non-mockable objects but it has a very long tail like HttpRequest, HttpResponse, HttpSessionState, HttpServerUtility etc etc. And this is the exact thing that the System.Web.Abstraction provides, all wrappers around the non-mockable objects of HttpContext. But still, both the HttpModule and HttpHandler depends upon the original HttpContext which I hope will change in ASP.NET 4.0. till then we need to create a super layer for making it Unit Testable.
