• Architecture When and Where to use Interface

  Hi All, I have a question here.Im bit confused of interface usage. Is it correct to have a separate separate interface for data objects I have around 10 business classes and have corresponding 10 data classes. Do we need to have a separate separate interfaces for each and every data class What is the correct norms of using interface Please clarify this. Thanks in advance. I think the question to ask here is why do both customerDL and EmployeeDL implement IPeople Is there a situation in which customerBL calls a method on IPeople and actually gets to EmployeeDL If customerBL is actually using customerDL all the time then there is no need for an interface between them... So I think the solution is to stop using ...Show All

  See the following example of how to insert a valid numeric value (a Decimal) using the System.Data.OracleClient that cannot be retreived using the same System.Data.OracleClient.

• .NET Development Application Design Question

  I have an database application that runs in a computer which has no static IP. I am going to build a web service that will retrieve information from that database and display it on a web site as users request it. something like a tracking system. My problem is, i can't send every record from my existing database to the web service (which will log it to a second database) because only 1 out of 100 records will be queried. it would be a waste of bandwidth and space. I need to implement the web service so that when a customers requests information it retrieves the data from the existing database (computer with no static IP). Any ideas would be greatly appreciated. Let's see if i can get this thread started. O ...Show All

• Visual Studio 2008 (Pre-release) Passing 3MB DataSet via WCF - Best Practice

  Hi In our application we have several DataSets with about 2-4MB of size. Each DataSet contains of only one single DataTable. The data has to come from the server to a client via WCF. Client and server are in the same LAN. What are best practices to pass the data The only thing I think I can be sure about is that I should use binary encoding for the binding. The following questions are still not clear for me: Which binding should I use - netTCP or WSHttp I know that a DataSet produces overhead, but does this really matter in my case If the DataSet produces to much overhead, what should I do best to get the data to the client fast Should I use streaming or better the standard buffering Which timeout and max size settings do I have to t ...Show All
